Digitalization is the bedrock of information technology and science. Businesses around the world are increasingly investing in digitalization at a frantic pace with Machine Learning (ML) and Artificial Intelligence (AI) witnessing significant adoption in day to day operations of organizations.
2020 is envisaged as a tipping point for Machine Learning adoption and percolation. Several Machine Learning Frameworks have been developed and are in vogue today. The selection of the right Framework for your business is a daunting exercise, and getting to know the best fit software could be a challenge. This article provides you with a good grip of ML frameworks available today and could help you in your search for the right fit framework for your use or business.
Let us run by a brief concept of Machine Learning and some of the most used Machine Learning frameworks and in trend in 2021.
What is ML?
ML is an area of computational science that deals with the analysis and interpretation of patterns and structures in large volumes of data to help learn, reason, and to support business decision making without or with very little need for human interface. Machine Learning permits users to feed large volumes of data to a computer algorithm that will analyze and generate data-driven decisions and recommendations. If there are any errors or outliers in information identified, the algorithm is structured to take this new information as an input to improve its future output for recommendations and decision making.
Simply put, ML is a subset of AI that supports organizations to analyze data, learn, and adapt on an ongoing basis to help in decision making.
What is a Machine Learning Framework?
A simple definition could be to think of it as a tool or library that allows developers to build ML models or Machine Learning applications with ease without having to get into the nuts and bolts of the base or core algorithms.
Best Machine Learning Frameworks
Now let us dive into some of the well-known Machine Learning Frameworks in detail:

Types of Machine Learning
1. Supervised Machine Learning
Supervised Machine Learning algorithms attempt to build relationships and dependencies between target predictive output and input features so that the output values can be predicted for new data sets based on past learning in relationships and dependencies from previous data sets.
It is important here that human experts act as teachers, and training data is fed to a computer algorithm containing the input predictors. The computer is shown the correct output. From output data, the computer algorithm can learn patterns. Supervised Machine Learning uses Predictive Models and Labeled data.
The major type of Supervised ML typically addresses regression and classification problems. Some of the common algorithms that Supervised ML handle is Nearest Neighbor, Naive Bayes, Decision Trees, Linear Regression, Support Vector Machines (SVM), and Neural Networks.
2. Unsupervised Machine Learning
Here, the system is trained using unlabeled data. There is no human interface or teacher whatsoever, and the computer might be capable of teaching humans or revealing new outputs based on its learning from patterns in data. This is a classic example where the algorithms are helpful in situations where the user or expert doesn’t exactly know what he wants from the data.
Further, the Machine Learning algorithms are majorly utilized in pattern detection and descriptive modeling, where there are no output labels. The algorithms use mining techniques on the input data to determine rules, detect patterns, and create a summary group of data points that helps to derive insights and describe data meaningfully and with a better purpose to users. Unsupervised ML uses Descriptive Models, and majorly includes Clustering Algorithms and Association Rule Learning Algorithms.
Facebook is a classic example of unsupervised ML. The ML Framework of Facebook detects hidden patterns and uses facial recognition features in photos and pictures to recommend new connections etc. for users.
3. Reinforcement Machine Learning
Reinforcement ML is a method that aims at using observations collected from interactions with the immediate environment for taking actionable decisions that could help in maximizing returns and benefits or minimize risk. The reinforcement learning algorithm also is known as “the agent,” learns continuously and in an iterative manner from the environment. During the process, the agent goes through experiential learning from the environment until it explores all the possible states before suggesting recommendations or decisions.
Now, let us see some example algorithms for Reinforcement Learning. These are Model Free Algorithm (MFA) as against a model-based algorithm where a typical transition probability distribution and reward functions with relevance to the Markov decision process (MDP) is used. An MFA is capable of handling dilemmas using stochastic transitions and rewards and without the requirement of any adaptations. The common and most used algorithms are:
- Monte Carlo
Note that the above is only a list of sample algorithms. These algorithms are a little complex to be explained in a few words since these have wide and deep applications in data science. As a knowledge seeker, you need to master the various algorithms and their approaches, and its application in programming to get your desired outcomes.
