Clustering algorithm

Exploring factors and causes in student stress using a clustering algorithm

4 minute read

Published:

Recently, I came across this kaggle dataset for student stress suvery conducted nationwide. There are 20 factors where participants must give a numerical score to rate how prevalent these factors are. This dataset is pretty interesting as stress is something that affects us all, and understanding what factors are correlated with increased stress levels can improve our quality of life.

Introduction to normalising flows

In the field of Gravitational-Wave astronomy, I see a transition from traditional stochastic sampling methods such as Monte Carlo Markov Chains and nested sampling towards something called normalising flows. As our inference problems become harder due to the increasing volume of data, we need faster inference methods. In this blog post, we will go through what is a normalising flow and can it solve inference problem that are intractably long for traditional methods.

Introduction to Gaussian processes

I have used Gaussian process and it being used extensively in fields such as astrophysics. They are very useful and flexible models that can be applied to timeseries data. However, I often find it difficult to explain a Gaussian process (GP) to a non-expert in a short amount of time. While it is easy to use many of the GP libaries available, wrapping your head around the theoretical concepts can be challenging.
