Academic Projects:

1.Facebook metrics Dataset, 2014 Fall-2019

Visualizations and analyzing the data.

Mean square error and predictions will be calculated.

Linear regression model, regression tress correlation analysis will be performed.

Tools: R studio.

2.Leukemia incidence rates for united states by state, 2012-2016. Fall-2019

Visualized and Analyzed the data.

Using micromap converted bad graph to good graph.

Tools used- R studio to generate linked micromaps, maptails.

3.Skybus: Undergrad

Major project on “SKY BUS” which is also known as driverless hanging train, it shows the automatic movement of train from one station to another. It included the coding of 89C51 microcontroller. This relation between hardware and software, implementing hardware through software increased my thirst to know more about it.
