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.

Use a Script Monkey in your codebase at all locations where you need to change things manually. All that involves is writing an extra comment saying ‘Script Monkey’. Later on, search for all monkeys in the script and make the changes. Simple.

How does gender affects pay? In this short exploration, I use #tidytuesday dataset provided by UK Government to visualise gender gaps using R. And why are women working at churches paid 40% less bonus than men?

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).

Facebook provides data on all ad funding related to social issues, politics and elections. Here is a simple plot and table to explore the most prominent advertisers.

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

Research Paper on Malaria Vaccine Coverage Prediction

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.

Research paper on statistical modelling and analysis of computer-simulated datasets

Measuring efficiency of Indian higher education institutes using Data Envelopment Analysis

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.
