## Entropy, information gain, and Gini impurity(Decision tree splitting criteria) Paid Members Public

Decision trees are supervised machine-learning models used to solve classification and regression problems. They help to make decisions by breaking down a problem with a bunch of if-else-then-like evaluations that result in a tree-like structure. For quality and viable decisions to be made, a decision tree builds itself by splitting

## Decision Trees and Random Forests(Building and optimizing decision tree and random forest models) Paid Members Public

In the modern world, so much data is present on the internet. Organizations need efficient and rigorous algorithms to handle these huge chunks of data, make practical analyses, and provide appropriate decisions relevant to maximizing their profits and market presence. There are such algorithms commonly used today for decision-making processes.

## Logistic regression in Python with Scikit-learn Paid Members Public

In linear regression, we tried to understand the relationship between one or more predictor variables and a continuous response variable. This article will explore logistic regression, where the response variable will be discrete or categorical. What is classification? Classification is a supervised machine learning problem of predicting which category or

## Linear regression in Python with Scikit-learn (With examples, code, and notebook) Paid Members Public

Scikit-learn is a handy and robust library with efficient tools for machine learning. It provides a variety of supervised and unsupervised machine learning algorithms. The library is written in Python and is built on Numpy, Pandas, Matplotlib, and Scipy. In this tutorial, we will discuss linear regression with Scikit-learn. What

## Seaborn tutorial Paid Members Public

Seaborn is a simple, easier-to-learn open-source data visualization Python library that provides fantastic default styles and color palettes to create attractive and informative statistical plots. Seaborn is built on top of Matplotlib. Matplotlib treats Figures and Axes as objects and focuses on how to draw them. Seaborn has a dataset-oriented,

## Data visualization with Matplotlib Paid Members Public

💡"A good sketch is better than a long speech"(Napoleon Bonaparte).  Organizations collect and analyze vast amounts of data from sales revenue, marketing performance, customer interactions, inventory levels, production metrics, staffing levels, costs, etc. This can be too much data that it is impossible to effectively understand and evaluate it

## Python for data science tutorial (Complete guide with examples and notebook) Paid Members Public

This article will dive into fundamental Python concepts you need to understand before using Python for data science and machine learning. Let's dive right in! What is Python? Python is the language of preference for most data scientists. It is a general-purpose, high-level programming language that supports object-oriented, structured, and

## Pandas tutorial (A complete guide with examples and notebook) Paid Members Public

Pandas is an open-source Python library that provides a rich collection of data analysis tools for working with datasets. It borrows most of its functionality from the NumPy library. Therefore, we advise that you go through our NumPy tutorial first. As we dive into familiarizing ourselves with Pandas, it is
