Different Machine Learning Algorithms For Data Science

Machine Learning is a study that gives computers and systems the ability to learn autonomously without any programming. Let’s say that you just installed a shopping app and your first search is about books. The second search results show you new book collections. The application will not show you the products that you searched for. It is machine-learned and acclimated. How does the machine adapt to the user’s needs? Simple! simply by using the data. In this example, books are provided as data to the app. The application displayed the data (new book collections) that you might be interested in. This is Machine Learning.

The first picture shows you how to search for books. The second picture shows how the homepage of the application is displayed based upon your interests.
Machine Learning is an application of artificial intelligence (AI) that allows systems to learn from their experience without the need for programming. Machine Learning is the creation of computer programs that can learn by themselves using data.
Different Machine Learning algorithms are available for data science.
Supervised Learning: Supervised Learning is a subcategory under Machine Learning and Artificial Intelligence. Supervised learning is designed to improve the accuracy of your predictions. Machine learning can use labeled datasets to train algorithms for prediction or classification.

Supervised learning is like a classroom, where the teacher is the supervisor and the student the Learning Agent. The figure shows that the supervisor already has the desired output and will expect the Learning Agent to produce the same or very similar output. This Learning Agent takes the environment’s training data and attempts to produce the desired output. Once the Learning Agent has produced the output, it is sent by the adder. If it is identical to the desired output, the supervisor will accept it. Otherwise, it will be sent back by the adder to the Learning Agent. This will continue until the Learning Agent produces desired output. Supervised learning is, in simple terms, machine learning that occurs under the supervision of a supervisor.
Unsupervised learning: This is the primary function of unsupervised learning. It handles raw data and converts it into structured data. Nearly every field of modern life has a lot of raw data. Even computers can create log files of raw information. Machine learning is therefore essential.

Unsupervised learning is not like supervised learning. There is no supervisor and no desired output. The Learning Agent collects data from the environment and attempts to improve its output by comparing it with the previous output.
Reinforcement learning: This algorithm teaches the machine how to make certain decisions. This is how it works: The machine is constantly exposed to a learning environment that allows it to use trial and error to improve its skills. The machine draws on its past experience to make business decisions that are accurate. Reinforcement learning is demonstrated by the Markov Decision Process.

These algorithms can be further divided into the following:
Linear regression: Linear regression is one of the most popular and well-known Machine Learning algorithms. Linear Regression is used to predict variables such as age, salary, sales, price, and so forth.
This algorithm shows the linear relationship between the dependent (Y), and independent (X). Linear Regressions show the linear relationship between the variables. We can see how the dependent variable changes with respect to the change of the independent variable.
