Learn how ML DataOps has an impact on many sectors around the world

Over the past decade, commercial machine learning (ML), applications have evolved from conception to testing to deployment. As the industry progresses through the cycle of artificial intelligence (AI), the need for efficient, scalable operations has resulted in the creation of maps. It is therefore important to fully understand ML DataOps and its impact on various sectors.

What is ML DataOps?

ML heavily relies on data collection, analysis, and creation. The AI ecosystem has seen a shift to a data-centric approach over the last year. This is in contrast to the model-centric approach. Data is the most important factor in ensuring the success of ML models in the real world.

ML DataOps, an ML-based data management system, is now in the spotlight. It allows us to manage large amounts of data as it flows through the cyclical journey that is AI training and deployment. This is crucial to ensure the sustainability of the resulting AI solutions. There is also a need to transition from production to testing, which must be done through repeatable and scalable processes. Customers can also benefit from insights derived from the data to help them accelerate the development of production-grade models.

Companies are focused on different aspects within the ML DataOps ecosystem’s data pipeline. The solutions offered generally fall within the following categories:

3. End-to-end processes: When dealing with enterprise-grade data pipes, efficient and insight-driven processing can make a significant difference in time and cost. Companies often focus on end-to-end solutions to such simplified processes.

2024 is the year of ML DataOps

2024 has seen remarkable growth so far. This is why 2023 will see more investment and development.

First, AI products are being put into production. This is huge. Finance and retail are putting cutting-edge models into production. Once released, feedback loops will be provided. An enterprise’s ability to receive feedback from their model changes will require them to adjust their ML data operations in order to keep up with the changing demands. Edge cases will be returned by field algorithms, which will require data operations to resolve.

Data pipelines need scale and experts in-loop. Enterprises will need to ensure that their annotators are knowledgeable about the product and domain requirements in order to scale efficiently. As they improve their models’ performance, this will result in faster market releases.

End-to-end AI data solutions will soon be available on the market. The technology behind AI is evolving as AI progresses. Combining technology with human-in-the-loop expertise provides enterprises an end-to-end solution when they deploy their models in the field. The best data will be produced by combining the right expertise, judgment, and technology.

Using the Right Processes

Your ability to use technology is as important as its quality. This is why enterprises creating AI applications need to make sure they have the right processes in place for their ML DataOps. Using iMerit as an AI data solution provider gives companies access to domain experts who can help with every stage of a company’s ML DataOps process. This includes requirements definition, workflow engineering, and domain skill identification.

Impact Across Various Sectors

Healthcare: Healthcare has been at the center of attention since the COVID-19 pandemic. To make healthcare accessible and effective, there are many challenges.

Organizations can use data-driven insights to predict the best clinician mix for a particular department. It can also help in the creation of a value-based environment by automating clinical operations, such as physician recruitment, scheduling clinical staff, and clinical systems.

DataOps can help in the creation of patient-centric systems that deliver better-operating processes and customer engagement. This DataOps-led architecture will help to assess capabilities and tools to identify and recommend patient-centric methods to improve connectivity, collaboration, and engagement with patients.

The financial services industry can benefit from the use of innovative data and analytics to improve decision-making and innovation. These tools allow financial service providers to optimize data analytics and enable companies to combine machine intelligence and human expertise to create a trusted ecosystem. Data analytics, for example, can be used by banks to collect customer insights and use this information to make strategic decisions about introducing new products or improving existing business models.

Automobile: Countries are becoming more aware of the potential for autonomous vehicle technology (AV) and taking steps to support its growth. The US, for example, has enacted a $1 trillion infrastructure bill. It includes many suggestions for modernizing infrastructure in order to encourage widespread adoption of AVs. Manufacturers and innovators need to learn how to create AI models that can be used on any road.

Modern transportation is at an all-time high. One of the greatest challenges in the 21st Century is to reduce road accidents and other safety violations. AI-led solutions can significantly aid human drivers and allow for driverless mobility. This sector is home to many leaders in AI, software engineering, and device engineering.

Retail: This industry has a lot of data. From product catalogs to customer information, to customer questions and complaints, it collects a lot. These data can be overwhelming for decision-makers trying to solve a problem. Retail is a sector that appeals to all senses. Data operations are required to interpret any information, whether it is audio, video, text, or both. But, particularly in retail, we need human capabilities to dig into consumer behavior and extract insights that can be used for decision-making. Data-driven solutions can help retailers analyze this huge amount of data and also speed up decision-making in this dynamic industry.

Industries that adopt AI and data solutions will eventually have to create an ecosystem that is able to learn from and help in decision-making. This combination with human-in-the-loop processes provides the perfect blend of technological innovation, human intelligence, and human ability to help businesses achieve their goals and solve problems.

Build And Automate Machine Learning

Intel keeps on eating up new businesses to work out its machine learning and AI tasks.

In the most recent move, TechCrunch has discovered that the chip goliath has obtained chúng tôi an Israeli organization that has manufactured and works a platform for information scientists to assemble and run machine learning models, which can be utilized to prepare and follow various models and run examinations on them, construct proposals and the sky is the limit from there.

Intel affirmed the securing to us with a short note. “We can affirm that we have procured Cnvrg,” a representative said.

Intel isn’t uncovering any monetary terms of the arrangement, nor who from the startup will join Intel.

Cnvrg, helped to establish by Yochay Ettun (CEO) and Leah Forkosh Kolben, had raised $8 million from financial specialists that incorporate Hanaco Venture Capital and Jerusalem Venture Partners, and PitchBook gauges that it was esteemed at around $17 million in its last round.

It was just seven days back that Intel made another procurement to help its AI business, additionally in the region of machine getting the hang of demonstrating: it got SigOpt, which had built up a streamlining platform to run machine picking up displaying and reenactments.

It contends with any semblance of Databricks, Sagemaker and Dataiku, just as more modest activities like chúng tôi that are based on open-source structures.

Cnvrg’s reason is that it gives an easy to use platform to information scientists so they can focus on formulating calculations and estimating how they work, not fabricating or keeping up the platform they run on.

While Intel isn’t saying much regarding the arrangement, it appears to be that a portion of a similar rationale behind a week ago’s SigOpt procurement applies here also: Intel has been pulling together its business around cutting edge chips to more readily contend with any semblance of Nvidia and more modest players like GraphCore.

So it bodes well to likewise give/put resources into AI apparatuses for clients, explicitly administrations to help with the process stacks that they will be running on those chips.

It’s prominent that in our article about the Core complementary plan a year ago, Frederic noticed that those utilizing the platform in the cloud can do as such with Nvidia-improved holders that sudden spike in demand for a Kubernetes bunch.

Intel’s attention on the up and coming age of figuring expects to balance decreases in its inheritance activities. In the last quarter, Intel announced a 3% decrease in its incomes, driven by a drop in its server farm business.

It said that it’s anticipating the AI silicon market to be greater than $25 billion by 2024, with AI silicon in the server farm to be more prominent than $10 billion in that period.

Artificial Intelligence Vs Machine Learning Vs Deep Learning: What Exactly Is The Difference ?

This article was published as a part of the Data Science Blogathon.

range of applications has changed the facets of technology in every field, ranging from Healthcare, Manufacturing, Business, Education, Banking, Information Technology, and whatnot!

Although these words are familiar and used widely, they are often used interchangeably. But there is a vast difference between all of these.

In this article, we will explore these buzzwords and learn the difference between them.

Artificial Intelligence

Simply put, “Artificial Intelligence is the ability of machines to function like the human brain.”

Whenever we think of Artificial Intelligence, the first thing that strikes our mind is Robots. A few decades ago, ‘Robots’ fascinated us the most with movies showcasing Robots / Superhumans performing insanely tough jobs effortlessly and living on par with humans. Now Robots like Sophia are a reality and we find AI everywhere. Right from robotic vacuum cleaners, virtual assistants like SIRI, robots that perform surgeries in healthcare, robots that write codes, and of course the self-driving cars and trucks – most of these are a reality and the world of Artificial Intelligence is rapidly evolving. Starting with IBM’s chess-playing computer ‘Deep Blue’ which won a chess match against World Champion, to ‘Google’s AlphaGo’, we have seen fascinating discoveries in this AI revolution.

In simple terms, Artificial Intelligence is all about training machines to mimic human behavior, specifically, the human brain and its thinking abilities. Similar to the human brain, AI systems develop the ability to rationalize and perform actions that have the best chance of achieving a specific goal.

Artificial Intelligence focuses on performing 3 cognitive skills just like a human – learning, reasoning, and self-correction.

The evolution of Artificial Intelligence is considered the fourth Industrial Revolution ~ UBS

Experts say, just like how the first 3 industrial revolutions changed the course of the world, the fourth revolution, powered by Artificial Intelligence, IoT and Cloud will surely change the course of humanity and our planet Earth. And enthusiasts are running to learn any AI Course Online.

Let’s have a quick look at the three broad categories of Artificial Intelligence and how we are rapidly evolving in these areas!

1. Artificial Narrow Intelligence

2. Artificial General Intelligence

3. Artificial Super Intelligence

Artificial Narrow Intelligence

Artificial Narrow Intelligence systems are designed and trained to complete one specific task and are often termed as Weak AI / Narrow AI. The chatbots that answer questions based on user input, voice assistants like Siri, Alexa, and Cortana, facial recognition systems, AI systems that search the internet, are examples of Weak AI. They are intelligent at performing the specific tasks that they are programmed to do so.

Narrow AI doesn’t mimic human intelligence, rather it just simulates human behavior based on a set of parameters and input data. Weak AI still requires some amount of human intervention in terms of defining parameters for learning algorithms, feeding relevant training data, and ensuring the accuracy of prediction.

You can think of it as an infant who listens to instruction from adults and performs the functions as directed.

Artificial General Intelligence

Artificial General Intelligence is when the AI systems/machines would perform on par with another human. This also means the ability of the machine to interpret and understand human tone and emotions and act accordingly. This is also called Strong AI and we are still scratching the surface of Strong AI. As Machine Learning capabilities continue to evolve, AI will progress and we will reach there soon.

Artificial Super Intelligence

Artificial Super Intelligence/Super AI is when an Artificial Intelligent machine would become self-aware and surpass human’s intelligence and ability. Although there is so much exciting research happening around this area, there are warnings from scientists as well.

Oxford University Professor and New York Times best-selling author of the book “Superintelligence: Paths, Dangers, Strategies”, Nick Bostrom says,

” The biggest threat is the longer-term problem, introducing something radical that’s super intelligent and failing to align it with human values and intentions. This is a big technical problem. We would succeed at solving the capability problem before we succeed at solving the safety and alignment problem.”

Okay! That’s a lot about Artificial Intelligence!

As we have a fair idea of Artificial Intelligence; are you wondering how the computer system/machine can mimic human actions and perform predictions, automation, and make decisions?

That is where Machine Learning comes into the picture.

Machine Learning

Machine Learning is naturally a subset of AI. It provides the statistical methods and algorithms and enables the machines/computers to learn automatically from their previous experiences and data and allows the program to change its behavior accordingly.

Machine Learning provides many different techniques and algorithms to make the computer learn. Decision trees, Random Forests, Support Vector Machines, K Means clustering – these are just to name a few.

Demand forecasting sales of products, predicting customer behavior, gauging customer sentiments from their social media behavior – these are some use cases where machine learning models are used. Machine learning algorithms work well when the input data is reasonably good enough. When the size of data explodes, we need to look at more efficient algorithms and techniques and that is where Deep Learning finds its hotspot.

OTT platforms like Netflix and Amazon Prime use Machine Learning to recommend movies based on the user’s past viewing data and it constantly improves by learning from past experiences.

In e-commerce, companies like Amazon and Flipkart use Machine Learning to learn the user’s preferences and give product recommendations based on previous purchases and viewing history.

The application of Machine Learning in the real world is humongous!

Now we have a clear idea that Machine Learning and AI are not just the same. Machine Learning is one of the ways to achieve Artificial Intelligence.

Just like anything else, Machine Learning has its shortcomings and that is where Deep Learning comes into the picture!

Machine Learning models don’t perform very well when the volume and complexity of data increase multifold. They need some sort of human intervention and guidance whereas Deep Learning models learn from data and previous experience and correct themselves progressively.

Let’s look at the next buzzword – Deep Learning!

Deep Learning

Deep Learning can be thought of as the evolution of Machine Learning which takes inspiration from the functioning of the human brain. Deep Learning is used to solve complex problems where the data is huge, diverse, less structured. Deep learning models are built on top of Artificial Neural Networks, which mimic how the human brain works.

Let’s look at the basic functioning of our brain to understand how Neural Networks work. Our human brain has neurons which are the basic functional units of our brain. The neurons transmit information to other nerve cells, muscles, and glands and also receive input from other neurons, enabling the brain to make decisions.

Imagine, you are a small kid and you see a pot filled with hot water. When you see it you wouldn’t understand it’s hot unless someone says so. If you touch the hot pot, the nerves in your fingers carry this information to the brain, and the neurons process this information and send the signal back to your fingers and you would sense the heat. Next time you see a hot pot, your brain will remember the previous incidents and will remind you that you will feel hot if you touch it.

And our brain continuously learns from inputs from the environment and previous experiences and makes the best possible decision in every scenario. This is pretty much what Deep Learning does! It learns progressively from raw data and previous experiences and corrects itself without explicit programming.

Artificial Neural Networks, Convolutional Neural Networks, and Recurrent Neural Networks are some of the Deep Learning algorithms used to solve real-world problems.

Self-driving cars and trucks, Virtual Assistants like Alexa, Siri, and Google Assistant, Speech recognition systems, Computer vision, Robotic Surgeries are all interesting applications of Deep Learning.

” At the beginning of 2023, the number of bytes in the digital universe was 40 times bigger than the number of stars in the observable universe” ~ World Economic Forum

To summarize, a lot of AI systems are powered by Machine Learning and Deep Learning algorithms. AI is achieved through Machine Learning, and Deep Learning and they are not the same.

I hope this article gave you a fair idea of Artificial Intelligence, Machine Learning, and Deep Learning.

Understand Machine Learning And Its End

This article was published as a part of the Data Science Blogathon.

What is Machine Learning?

Machine Learning: Machine Learning (ML) is a highly iterative process and ML models are learned from past experiences and also to analyze the historical data. On top, ML models are able to identify the patterns in order to make predictions about the future of the given dataset.

Why is Machine Learning Important?

Since 5V’s are dominating the current digital world (Volume, Variety, Variation Visibility, and Value), so most of the industries are developing various models for analyzing their presence and opportunities in the market, based on this outcome they are delivering the best products, services to their customers on vast scales.

What are the major Machine Learning applications?

Machine learning (ML) is widely applicable in many industries and its processes implementation and improvements. Currently, ML has been used in multiple fields and industries with no boundaries. The figure below represents the area where ML is playing a vital role.

Where is Machine Learning in the AI space?

Just have a look at the Venn Diagram, we could understand where the ML in the AI space and how it is related to other AI components.

As we know the Jargons flying around us, let’s quickly look at what exactly each component talks about.

How Data Science and ML are related?

Machine Learning Process, is the first step in ML process to take the data from multiple sources and followed by a fine-tuned process of data, this data would be the feed for ML algorithms based on the problem statement, like predictive, classification and other models which are available in the space of ML world. Let us discuss each process one by one here.

Machine Learning – Stages: We can split ML process stages into 5 as below mentioned in the flow diagram.

Collection of Data

Data Wrangling

Model Building

Model Evaluation

Model Deployment

Identifying the Business Problems, before we go to the above stages. So, we must be clear about the objective of the purpose of ML implementation. To find the solution for the given/identified problem. we must collect the data and follow up the below stages appropriately.

Data collection from different sources could be internal and/or external to satisfy the business requirements/problems. Data could be in any format. CSV, XML.JSON, etc., here Big Data is playing a vital role to make sure the right data is in the expected format and structure.

Data Wrangling and Data Processing: The main objective of this stage and focus are as below.

Data Processing (EDA):

Understanding the given dataset and helping clean up the given dataset.

It gives you a better understanding of the features and the relationships between them

Extracting essential variables and leaving behind/removing non-essential variables.

Handling Missing values or human error.

Identifying outliers.

The EDA process would be maximizing insights of a dataset.

Handling missing values in the variables

Convert categorical into numerical since most algorithms need numerical features.

Need to correct not Gaussian(normal). linear models assume the variables have Gaussian distribution.

Finding Outliers are present in the data, so we either truncate the data above a threshold or transform the data using log transformation.

Scale the features. This is required to give equal importance to all the features, and not more to the one whose value is larger.

Feature engineering is an expensive and time-consuming process.

Feature engineering can be a manual process, it can be automated

Training and Testing:

the efficiency of the algorithm which is used to train the machine.

Test data is used to see how well the machine can predict new answers based on its training.

used to train the model.


Training data is the data set on which you train the model.

Train data from which the model has learned the experiences.

Training sets are used to fit and tune your models.


learnt good enough from the experiences it got in the train data set.

are “unseen” data to evaluate your models.

Test data: After the training the model, test data is used to test its efficiency and performance of the model

The purpose of the random state in train test split: Random state ensures that the splits that you generate are reproducible. The random state that you provide is used as a seed to the random number generator. This ensures that the random numbers are generated in the same order.

Data Split into Training/Testing Set

We used to split a dataset into training data and test data in the machine learning space.

The split range is usually 20%-80% between testing and training stages from the given data set.

A major amount of data would be spent on to train your model

The rest of the amount can be spent to evaluate your test model.

But you cannot mix/reuse the same data for both Train and Test purposes

If you evaluate your model on the same data you used to train it, your model could be very overfitted. Then there is a question of whether models can predict new data.

Therefore, you should have separate training and test subsets of your dataset.

MODEL EVALUATION: Each model has its own model evaluation mythology, some of the best evaluations are here.  

Evaluating the Regression Model.

Sum of Squared Error (SSE)

Mean Squared Error (MSE)

Root Mean Squared Error (RMSE)

Mean Absolute Error (MAE)

Coefficient of Determination (R2)

Adjusted R2

Evaluating Classification Model.

Confusion Matrix.

Accuracy Score.

Deployment of an ML-model simply means the integration of the finalized model into a production environment and getting results to make business decisions.

So, Hope you are able to understand the Machine Learning end-to-end process flow and I believe it would be useful for you, Thanks for your time.


Machine Learning Is Revolutionizing Stock Predictions

Stock predictions made by machine learning are being deployed by a select group of hedge funds that are betting that the technology used to make facial recognition systems can also beat human investors in the market.

Computers have been used in the stock market for decades to outrun human traders because of their ability to make thousands of trades a second. More recently, algorithmic trading has programmed computers to buy or sell stocks the instant certain criteria is met, such as when a stock suddenly becomes cheaper in one market than in another — a trade known as arbitrage.

Software That Learns to Improve Itself

Machine learning, an offshoot of studies into artificial intelligence, takes the stock trading process a giant step forward. Pouring over millions of data points from newspapers to TV shows, these AI programs actually learn and improve their stock predictions without human interaction.

According to Live Science, one recent academic study said it was now possible for computers to accurately predict whether stock prices will rise or fall based solely on whether there’s an increase in Google searches for financial terms such as “debt.” The idea is that investors get nervous before selling stocks and increase their Google searches of financial topics as a result.

These complex software packages, which were developed to help translate foreign languages and recognize faces in photographs, now are capable of searching for weather reports, car traffic in cities and tweets about pop music to help decide whether to buy or sell certain stocks.

Mimicking Evolution and the Brain’s Neural Networks

A number of hedge funds have been set up that use only technology to make their trades. They include Sentient Technologies, a Silicon Valley-based fund headed by AI scientisk Babak Hodjat; Aidiya, a Hong Kong-based hedge fund headed by machine learning pioneer Ben Goertzel; and a fund still in “stealth mode” headed by Shaunak Khire, whose Emma computer system demonstrated that it could write financial news almost as well as seasoned journalists.

Although these funds closely guard their proprietary methods of trading, they involve two well-established facets of artificial intelligence: genetic programs and deep learning. Genetic software tries to mimic human evolution, but on a vastly faster scale, simulating millions of strategies using historic stock price data to test the theory, constantly refining the winner in a Darwinian competition for the best. While human evolution took two million years, these software giants accomplish the same evolutionary “mutations” in a matter of seconds.

Deep learning, on the other hand, is based on recent research into how the human brain works, employing many layers of neural networks to make connections with each other. A recent research study from the University of Freiburg, for example, found that deep learning could predict stock prices after a company issues a press release on financial information with about 5 percent more accuracy than the market.

Hurdles the Prediction Software Faces

None of the hedge funds using the new technology have released their results to the public, so it’s impossible to know whether these strategies work yet. One problem they face is that stock trading is not what economists call frictionless: There is a cost every time a stock is traded, and stocks don’t have one fixed price to buyers and sellers, but rather a spread between bid and offer, which can make multiple buy-and-sell orders expensive. Additionally, once it’s known that a particular program is successful, others would rush to duplicate it, rendering such trades unprofitable.

Another potential problem is the possible effects of so-called “black swan” events, or rare financial events that are completely unforeseen, such as the 2008 financial crisis. In the past, these types of events have derailed some leading hedge funds that relied heavily on algorithmic trading. Traders recall that the immensely profitable Long-Term Capital Management, which had two Nobel Prize-winning economists on its board, lost $4 billion in a matter of weeks in 1998 when Russia unexpectedly defaulted on its debt.

Some of the hedge funds say they have a human trader overseeing the computers who has the ability to halt trading if the programs go haywire, but others don’t.

The technology is still being refined and slowly integrated into the investing process at a number of firms. While the software can think for itself, humans still need to set the proper parameters to guide the machines toward a profitable outcome.

Technology and industry trends are shaping the next era of finance. Check out our complete line of finance industry solutions to stay ahead of the competition.

Knowledge Enhanced Machine Learning: Techniques & Types

This article was published as a part of the Data Science Blogathon.


In machine learning, the data is an esse of the training of machine learning algorithms. The amount of data a the data quality highly affect the results from the machine learning algorithms. Almost all machin rning algorithms are data dependent, and their performance can be enhanced until some thresh mount of the data. However, the traditional machine learning algorithm’s behavior tends to be constant after some data is fed to the model.

This article will discuss the knowledge-enhanced machine learning techniques that introduce hierarchical and symbolic methods with limited data. Here we will discuss these methods, their relevance, and working mechanisms, followed by other vital discussions related to them. These methods are proper when there is little data and a need to train an accurate machine-learning model. the article will help one to understand the concepts related to knowledge and enhance machine learning better, and will able to make efficient choices and decisions in case of limited data scenarios.

Knowledge Enhanced Machine Learning

As the name suggests, knowledge enhanced machine learning is a type of technique where the knowledge of machine learning algorithms is enhanced by human capabilities or human understanding. In this technique, the machine learning algorithms apply their knowledge, and human or domain knowledge is integrated.

We humans can be trained on limited data, meaning that humans can learn several things by seeing or practicing stuff quickly and with limited data. For example, If we see a particular device, let’s say a Laptop, we can easily classify it and say it’s a type of electronic device. Also, we can classify it as an HP, Dell, or another model.

Source – Google

Machine learning models can classify several objects and perform specific tasks very quickly and efficiently, but the only problem is the amount of data. Yes, it requires a lot more amount of data to train an accurate model. But the knowledge-enhanced machine learning approach comes into the picture; it combines majorly two fields, the first is the model’s knowledge, and the other is human knowledge or human capabilities.

Hierarchical Learning and Symbolic Methods are knowledge enhancement machine learning approaches where human knowledge can be used to train a machine learning model with limited data, and the model’s performance can be en d.

Hierarchical Learning

As discussed above, when we humans see particular objects, our human mind automatically tries to classify the object into several classes. Let’s try to understand the same thing by taking appropriate examples.

Source – Google

As discussed above, the human mind can be taken as a trained machine learning model on limited data that classifies the object as a spot into several categories. Let’s take an example to understand the same thing.

Let’s suppose you saw the dog. Looking at the dog, we can easily classify its parent category as a “pet” and classify the dog as a labrador, dalmatian, french bulldog, or poodle. Here we can see that there are several levels of hierarchy where every single layer has several categories, and based on the knowledge of hierarchy, we humans can classify objects.

To implement this approach, the machine learning model can be trained on every layer of the hierarchy, and the model can be hyper-tuned to obtain the hierarchical learning model.

Symbolic Methods

The symbolic methods are also a knowledge base machine learning approach that tries to integrate human knowledge to classify several objects and build an accurate machine learning model.

Some machine learning models are trained so that whenever they are given an unseen image or object, they can efficiently and accurately classify the particular thing. These models are trained on a large amount of data.

We implement the same thing in symbolic methods but with limited data. Here we create the description or tags for the various objects and feed the data to the model. As there is little data available, there will be few images to train the model on, but the description of many objects will still be available.

Source – Google

Once the model is trained on such data, it can efficiently classify the unseen objects without training in such an image dataset, as it will use the description or tags provided based on human knowledge. So here, human knowledge is used to create the descriptions or tags of several objects, and machine learning models are used to train on such data.

Hierarchical vs. Symbolic Methods

As both approaches use human knowledge, a gentle question might come to mind: What is the main difference between such techniques?

The hierarchical learning approach is more towards a hierarchy of an object and its classification. Here human knowledge is used to classify and create the hierarchy of an object. Then machine learning models are used to train the algorithm on every level of the hierarchy for limited data scenarios.

In Symbolic methods, human knowledge is used to create the descriptions or the tags for particular objects, where the machine learning models are trained on limited image data. This machine learning model can now perform classification tasks on unseen images using human-generated descriptions or tags.

In general, we can not say that one of the approaches is always better, it all depends on the specific scenario of the data models and problem statement. Both approaches are nowadays being used for better performance on limited data, but one could use a specific approach per the requirement and conditions associated.


This article discussed knowledge enhanced machine learning techniques and their types. The hierarchical and symbolic approaches are discussed in detail with their core intuition and the difference between such methods. These articles will help geeks to understand the limited data scenario better and in an efficient way. They will help in several interviews and examinations as it is more of an academic topic.

Some Key Takeaways from this article are:

1. Knowledge-enhanced machine learning is a technique where human knowledge is used to train a machine learning model.

2. In the hierarchical technique, the machine learning model is strained on every hierarchy level generated by human knowledge or domain experts.

3. Symbolic methods also use human knowledge to generate descriptions or tags related to several objects so that the machine learning model can also classify unseen images and objects.

4. Both of the approaches are useful for specific cases and can be implemented as per the requirement and problem statement related to machine learning.
