Learning Machine Learning From Scratch

The scope of Machine learning has evolved over the years, and at present, has a wide range of applications in all prominent industries. It enables the applications and software to make the browsing experience more immersive for the buyers through personalized recommendations. Therefore now could be the best time to build a career in Machine Learning. However, you should first know what the field demands of you.

For this, you need to enrol in the best machine learning course online. In this article, we will discuss the concept and types of Machine learning in detail so that you develop a clear understanding of this modern concept. 

Machine Learning: Concept

Machine learning is a branch of computer science and Artificial Intelligence(AI) that makes use of data and algorithms to learn from the data, identify patterns, and make decisions with minimal human interference.

It is a subset of artificial intelligence that enables machines to learn the way that humans learn, gradually improving its accuracy. It enables the user to feed valuable data to an algorithm and let the system analyze and make data-driven decisions based on the input data. 

This is the reason why Machine Learning does not rely upon a predetermined model and can learn directly from the information provided by the data.

Machine Learning: Types

Machine learning is classified on the basis of how an algorithm is able to become more accurate at predictions. Based on this parameter, Machine Learning is classified as supervised learning, unsupervised learning, and reinforcement learning.

1. Supervised Learning

Supervised machine learning is a type of Machine Learning in which the algorithms are supplied with well-labeled training data to train the machine. On the basis of the labeled data, the machine makes predictions about the output. In supervised learning, the user defines the variables that the algorithm has to assess. There are basically two types of variables- target and features.

The target variables are the variables that the users want to predict whereas feature variables are the ones that help us predict the target. Training the machine algorithm is just like training your pet. It is more like you show them a cat and say ‘cat’ and then show them milk and say ‘milk’ till it learns the difference between them.

2. Unsupervised Learning

Unsupervised machine learning is a Machine Learning technique in which models are trained using unlabeled training data. In unsupervised machine learning, the models themselves identify the hidden patterns and insights from the given set of data. It is similar to the learning that takes place in the human brain while learning about new concepts and things. 

Unlike supervised learning, there is only a feature variable and no target variable in unsupervised learning. Therefore, it often faces the challenges of clustering wherein the data inputs with the same traits are clustered together and associated with deciphering meaningful relationships within the set of data.

3. Reinforcement Learning

Reinforcement learning is an area of Machine Learning that uses the feed-based technique. In this technique, the machine learning models learn to make a series of decisions in accordance with the feedback that they receive for their actions. 

In this process, the machine gets positive feedback for each good action. On the other hand, when it gets negative feedback, a penalty is imposed. Unlike supervised machine learning, a reinforced model does not depend upon the labeled data and automatically learns using the feedback.

To implement a successful machine learning project, you need to have a good command of the programming language that is flexible, stable, and offers robust tools. Python offer all these features and more, and hence is considered the best programming language 

Therefore, implementing a successful machine learning project requires a programming language that’s stable, flexible, and offers robust tools. Python offers its all, so we mostly see Python-based machine learning projects. This is the reason why most machine learning certification courses teach Python.
