## 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 […]

## 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 […]

## 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 […]
