## What is data mining

Data mining is an interdisciplinary subfield of artificial intelligence, machine learning, statistics and so on which involves discovering patterns in large data sets. The goal of the data mining process is to extract information and hidden patters from a data set and transform it into an understandable structure . These hidden patterns are summary of […]

## How to install R and RStudio

R is popular tool used in Machine Learning,data analytics,business analytics,statistical analysis,bioinformatics. To use R efficiently we need another tool which is called as integrated development environment (IDE). RStudio is an integrated development environment (IDE) for R. For using R,we need following 1.Install R 2.Install R-Studio 3.Install R-Packages Mac Users To Install R Go to www.r-project.org […]

## Applications of Machine Learning

Machine learning and Artificial Intelligence is future of our world. Machine learning enables us to crunch big data (Talking of Petabytes of data ???.. Yes). Machine learning is the subfield of computer science that “gives computers the ability to learn without being explicitly programmed” (Arthur Samuel, 1959). You can think of your brain.How does that […]

## 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 […]

## Tools for Data Visualization

Let’s begin learning about what are the important tools which are used for Data Visualization by Data Scientist,Business Analyst,Data Analyst and so on Data visualization involves study of the visual representation of data. The goal of data visualization is to communicate information clearly and efficiently via statistical plots like pie chart,histogram,barplots,scatterplot,heatmap and so on. Data […]

## 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 […]

## How to begin with R and RStudio??

This is for those who have just installed R and RStudio and wants to begin with R. There are data objects in R like dataframes,vector,matrices,lists ,factors and so on. If you want to know about how to write these data objects in R or just wants to get started with R,then follow this video to […]

## 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 […]
