Neural Networks For Machine Learning in R

Neural networks almost mimics the working of human brain.The neurons are connected by axons in human brain.Same way we have neural units in neural networks. Neural networks consist of multiple layers.And each layer has neural units .One is input layer and one is output layer.In between them we have more layers also called as hidden […]

Decision Tree for Data Analytics in R

A decision tree is a model that uses a tree-like graph for finding outcome decisions with probabilities. Decision tree learning is a supervised classification learning. Its a popular tool in machine learning. A typical decision tree looks like below In above figure, 0 and 1 at leaf nodes represent outcome variable classes.Its a binary classification.Names […]

What is Data Analytics???

Discovery, interpretation, and communication of meaningful patterns in data is part of data analytics.Analytics is compulsory for business for describing, predicting, and improving business performance. It involves many fields like Statistics, Mathematics,computer science and operations research and so on. Statistician John Tukey defined data analysis in 1961 as: “Procedures for analyzing data, techniques for interpreting […]

Use of apply,lapply and sapply functions in R

This is for those who know about dataframes in R.If you want to do something either rowwise or column wise in dataset(or dataframe) then you can use functions like apply,lapply and sapply. Say We are given a dataset or dataframe which has three columns like age,weight and height and let’s say you have 1000 rows […]

What are Classification Algorithms?

Wants to know about Classification Models for Machine Learning and Data Analytics? Classification is the problem of identifying the category out of many catergoies given to which a new observation belongs on the basis of a data containing observations. It is a supervised machine learning where a training set of correctly identified observations is available. […]

Random Forest for Machine Learning in R

Random forests are supervised machine learning method for classification and regression. Random forest is way of averaging multiple decision trees which are trained on different parts of the same training set. In Decision tree we make splits on predictor variables to predict the target. In Random Forest,we build many decision trees and then take the […]
