Introduction to Logistic Regression

In this article, we’ll discuss a supervised machine learning algorithm logistic regression. Logistic regression is a probabilistic classifier. It outputs the probability of a point belonging to a specific class. The output lies between [0,1]. Logistic […]

Assumptions Made by Ordinary Least Squares(OLS)

Introduction: Ordinary Least Squares(OLS) is a commonly used technique for linear regression analysis. OLS makes certain assumptions about the data like linearity, no multicollinearity, no autocorrelation, homoscedasticity, normal distribution of errors. Violating these assumptions may reduce […]

Introduction to K-Nearest Neighbors

The K-nearest neighbor(K-NN) classifier is one of the easiest classification methods to understand and is one of the most basic classification models available. K-NN is a non-parametric method which classifies based on the distance to the […]

Linear Regression Using Statsmodels

Introduction: In this tutorial, we’ll discuss how to build a linear regression model using statsmodels. Statsmodels is a Python module that provides classes and functions for the estimation of many different statistical models, as well as […]

Machine Learning Pipeline

A machine learning pipeline bundles up the sequence of steps into a single unit. For example, in text classification, the documents go through an imperative sequence of steps like tokenizing, cleaning, extraction of features and training. […]

Cross Validation

Cross-validation is an important evaluation technique used to assess the generalization performance of a machine learning model. It helps us to measure how well a model generalizes on a training data set. There are two main […]

Pandas Introduction

In this article, we’ll discuss Pandas, which is the most popular python data analysis library. Data analysis is a process of cleaning, exploring, organizing, describing, and visualizing data. Pandas is mainly used for cleaning and exploring […]

Box and Whiskers Plot

Box plot, also known as box-and-whisker plot, helps us to study the distribution of the data and to spot the outliers effectively. It is a very convenient way to visualize the spread and skew of the […]

Introduction to Support Vector Machine(SVM)

INTRODUCTION: Support Vector Machine(SVM) is the most popular and powerful supervised machine learning algorithm which is used for both classification and regression. However, it is more popular and extensively used in addressing the classification problems of […]

Hierarchical Clustering

Hierarchical clustering is the second most popular technique for clustering after K-means. Remember, in K-means; we need to define the number of clusters beforehand. However, in hierarchical clustering, we don’t have to specify the number of […]
