For all those who are thinking what is Hacktober fest? It is an open-source coding event that occurs every year in the month of October wherein many programmers, hackers, developers, data scientists collaborate on projects through Github.

Whenever we come across any datasets, we see thousands or even millions of rows of data that do not make any sense. But this data has a lot of hidden potentials that can be discovered by a specialist. These specialists generally use data visualization tools to analyze data and draw insights from the data. Excel, Tableau, Google Data Studio, PowerBI, Python libraries like Seaborn, Matplotlib, etc. are some commonly used tools.

With decision trees, AI can make well-thought decisions without any human interference. Decision trees is a supervised learning algorithm which is used to solve both regression and classification problems. It is a predictive modelling approach that gives a graphical representation of decisions and every possible outcome because of that decision.

Before starting with Linear regression, let’s discuss the types of algorithms. There are mainly three types of algorithms namely: Supervised, Unsupervised and Reinforcement.

Data science has been the fastest-growing field in the last decade. But COVID 19 has forced us to put a hold on everything.
