Published in Towards Data Science·Jul 13Member-onlyA Deep Dive into Dimensionality Reduction with PCAA mathematical deep dive into a simple yet powerful dimensionality reduction algorithm — If you are unfamiliar with PCA, essentially it is an algorithm that converts a high dimensional dataset to a lower one. Principal Component Analysis (PCA) is a really powerful tool, especially when dealing with large, high-dimensional datasets. In this blog post, I attempt to explain how the PCA algorithm works…Data Science7 min read
Published in Towards Data Science·May 30Member-onlyAn Introduction to Bayesian InferenceA math + code introduction to Bayesian Inference methods — Markov Chain Monte Carlo and Variational Inference. — In the previous blog post, I gave an introduction to the world of Bayesian Statistics. It examined how Bayesian statistics presents a way to incorporate evidence into our model to obtain a better model. This process is known as inference, which is fancy mathematical speak for obtaining/approximating the posterior.Bayesian Statistics8 min read

As a Chemical Engineering student, my final project involved me having to design and optimize a chemical reactor. Personally, my goal was not to get the best grade but approach it as a data science problem, showcasing…Reactor Project7 min read
Published in Towards Data Science·Jan 14Member-onlyAn Introductory Primer to Bayesian StatisticsA mathematical introduction to the world of Bayesian Statistics — In 1748, philosopher David Hume wrote the essay “On Miracles” arguing that incredulous and miraculous stories written in the past should not be believed because they went against the law of nature. 15 years later, a posthumous paper by Reverend Thomas Bayes raised an even more important question, “How much…Data Science8 min read

They are great at being multi-purpose tools to visualize and explore the data but are not the best as your project becomes more complicated. For such projects, we will want code that is more structured and scalable to work with different…Data Science8 min read
Published in Towards Data Science·Dec 14, 2021Member-only5 Essential Concepts for New Data ScientistsData science can be extremely intimidating especially when just starting out. While it can be easy to use plug-and-play code snippets implementing popular machine learning algorithms, it cannot substitute for mathematical intuition. Here are some important concepts which I found to be rather essential to my data science journey. 1. Bias Variance Trade-off The…Data Science9 min read
Published in Towards Data Science·Sep 18, 2021Member-onlyUnderstanding RegularisationRegularisation is a powerful tool that can help tune models — At the start of this year, I had a very limited understanding of regularisation. To me, it was simply a tool to use when overfitting. If the model was having higher validation loss than train loss, adding L1 or L2 regularisation might be able to solve this issue. The truth…Data Science9 min read
