Twitter is shutting down Revue, the newsletter platform that I use for Next. Thus, I’m migrating to Substack. You shouldn’t need to do anything on your side.

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.

Population collapse is a theory that says if the growth rates continue to decline the way they are decreasing right now, we would reach population zero. It is a stage where the population neither grows, nor declines. That is, the number of births plus in-migrants equals the number of deaths plus out-migrants. While this may sound cheerful, you may not have considered the pitfalls yet.

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.

Bihar is one of the poorest states in India. Their over all literacy rate is 70% but there’s stark difference between girls (50%) and boys (70%). In 2007, the government decided to distribute bicycles to all girls for free in the hope to get higher school enrollment. The program was called Mukhyamantri Balika Cycle Yojna (Chief Minister’s Programme on Cycle for Girls). The program had astonishing improvements.

There’s a famous saying: All models are wrong but some are useful. How much of statistics is wrong and how much of it is useful? Some thoughts on Hans Rosling’s popular talk on global economic development and optimism.

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.
