Updated on Feb 6th, 2024


In the current times, Machine Learning is one of the fastest-growing technologies globally. Machine learning applications and custom solutions are gaining huge momentum and all thanks to the robust machine learning frameworks. Most of the big companies are considering these powerful and smart machine learning frameworks to automate their operations, optimize the process, and most importantly, get an edge over the competition. 

As per a report, the total funding during the pandemic year in machine learning was around $28.5 billion. Moreover, Fortune Business Insights also predicts that the machine learning development market will reach $117.19 billion by 2027! That’s huge as compared to other tech trends of the market.  

But, how to choose the best machine learning framework that could satisfy your project needs in 2022? Well, here’s the answer to it!  

In this blog, we will discuss the best machine learning frameworks, along with their features and pros & cons. But, first let’s get to know the Machine Learning Framework in brief.

  • Tensorflow offers comprehensive, flexible tools and libraries that make it easier for researchers to push information to the ML models. 
  • Apache Mahout is a robust, scalable machine learning library that runs on Hadoop MapReduce. 
  • The sci-kit-learn toolkit has a repertoire of supervised learning algorithms, which includes – Generalized linear models such as Linear regression, Decision Trees, Support Vector Machines, and Bayesian methods.  
  • Cognitive Services allow enterprises lacking the necessary AI research staff, infrastructure, and budget to select AI tools for their needs. 

What is a Machine Learning Framework?

It is not new that machine learning uses several algorithms to automate the various business operations and make machines mimic human behavior. And unless you are an expert in ML, these machine learning algorithms are very difficult to understand. So, machine learning frameworks simplify these complex algorithms so that you can easily implement ML in your enterprise applications.  

In other words, machine learning frameworks are an interface with which you can seamlessly deploy smart machine learning models for faster and automated working. Besides providing a faster working environment, machine learning frameworks even facilitate automation that could help you to step into a completely digital business era. What’s your thought on implementing machine learning solutions in your business?

PyTorch’s creators say that they have a philosophy – they want to be imperative. This means that we run our computation immediately. This fits right into the python programming methodology, as you don’t have to wait for the whole code to be written before getting to know if it works or not. you can easily run a part of the code and inspect it in real-time.  

PyTorch is a python based library built to provide flexibility as a deep learning development platform. The workflow of PyTorch is as close as you can get to Python’s scientific computing library – NumPynumpy. 

This framework was developed by Facebook, which is an open-source and scientific computing framework. Pytorch is a scripting language that is based on the LUA programming language. Pytorch offers various algorithms and scripting languages. 

Features of PyTorch include:

  • Its API is very simple to use. 
  • PyTorch uses python integrations coupled with a data science stack. 
  • It helps in building computational graphs whenever you want and in a simple way. 
  • You can change your graph if you want to use PyTorch, even at runtime.

  • Constantly getting better with community contributions. 

Cons of Google Cloud ML Engine:

  • The learning curve is a little bit steep; however, there are many free resources on the Internet. 
  • The product is getting lots of changes and contributions from the community, so it’s hard to follow what is going on with the product all the time. 



AutoML or Automatic Machine Learning is the process of automating algorithm selection, feature generation, hyperparameter tuning, iterative modeling, and model assessment. AutoML makes it easy to train and evaluate machine learning models. Automating repetitive tasks allows people to focus on the data and the business problems they are trying to solve.

  • Readily available algorithms, easy to use in your analytical projects 
  • Faster than Python sci-kit learn (in machine learning supervised learning area) 
  • It can be accessed (run) from Python, not only JAVA, etc. 
  • Well documented and suitable for fast training or self-studying 
  • In the beginning, one can use the clickable Flow interface (WEB UI) and later move to a Python console. There is then no need to click in H20 Flow 
  • It can be used as open-source 

Cons of H2O:

This is not really a drawback, but rather a warning – the Driverless AI is not a replacement for a data scientist yet, and will not replace data scientists in the next decade either. The Driverless AI feature delivers reliable results only if the analyst is sure about the meaning of input data. Data quality is usually a major issue, and no tool can detect the meaning of data in the input. Data scientists are also required for the business interpretation of the findings. So be careful, and do not rely on this feature without a good understanding of what it really does in each step.
