In this lab session, I share how to use apriori algorithm for association mining. The goal is to find useful causal and association rules which can help in designing promotions for the company. Plus, you get to see what’s served at an Indian cafe.
Support vector machines (SVM) are remarkable for the unification of geometric theory, elegant mathematics, theoretical guarantees with strong practical use cases. In this blog post, I demonstrate certain properties of SVM and how to use them with caret package in R.

Over the last few days, I dabbled with maps in R. Two days ago, I made a map of all the cities I’ve visited. Today, I thought to make street maps of some of them (and other cool cities).
A Simple Method to Calculate Distance between Discrete Variable
How much do the super rich really pay? Until now, the answer was unknown — thanks to privacy laws. Recently, tax returns of the super rich was leaked to ProPublica. I thought of exploring the billionaires and their tax rates.

Summary of my research work on forecasting coverage for Malaria vaccines
We applied a dynamic Gaussian process model to predict coverage for novel Malaria vaccines in 78 countries. Using publicly available WHO data on coverage of nine vaccines, we developed localised models for countries grouped using the human development index (HDI). We deployed convolutions of standard GP models with weights determined using singular value decomposition of time-series response matrix.
Using rTweet package in R to analyse live tweets from Twitter
I analyse my listening stats and patterns using R.
My first academic publication: a peer-reviewed book chapter on statistical modelling using Gaussian processes. We reviewed several GP models and correlation structures, and methods to handle numerical instabilities due to near-singular matrices. Finally, we reviewed several algorithms developed specifically for analysing big data obtained from computer simulators.
