## Introduction to the Perceptron Algorithm

Perceptron Algorithm The Perceptron model forms the basis of any neural network. This is where it all began and finally led to the development of “Neural Networks” or “Deep Learning” which is kind of the buzz word nowadays. In this article, I am going to show the mathematics behind the well-known Perceptron algorithm using a 2-input 2-output model. Although some amount of linear algebra…

## Introduction to Data Envelopment Analysis in R

Introduction to Data Envelopment Analysis Data Envelopment Analysis is a Performance Measurement technique which is used for comparing the performances of similar units of an organization. The units for which we are doing the performance analysis are called Decision Making Units (DMU). For example, we can compare all the McDonald’s outlets operating in the Delhi NCR Region to find out…

## Solving a Linear Optimization problem using R

Introduction to Linear Optimization Optimization is a technique for finding out the best possible solution for a given problem for all the possible solutions. Optimization uses a rigorous mathematical model to find out the most efficient solution to the given problem. To start with an optimization problem, it is important to first identify an objective. An objective is a quantitative measure…

## Linear Regression in R and its interpretation

Linear Regression Linear regression modeling is one of the most frequently used supervised learning technique. It is useful when the dependent variable is continuous (ratio or interval scale) and there exists a linear relationship between the dependent and independent variables. This post is a quick guide to perform linear regression in R and how to interpret the model results. In the…
