How to perform clustering with dimensionality reduction for large datasets

This post demonstrates how to perform clustering with dimensionality reduction using PCA which I learnt while completing the introduction to machine learning course by Udacity. PCA transforms larger datasets into a smaller subset of features which still contain a lot of the information in the larger dataset, which allows ML…

Introduction to Artificial Neural Networks

This article aims to give a beginner friendly introduction to artificial neural networks. Firstly, it is important to note that artificial neural networks are machine learning techniques which mimic the inner workings of the human brain where interconnected neurons process information in parallel. A neural network can be illustrated by…

Practice: Hyper parameter tuning for an overfitted decision tree classifier

This project was initiated as part of a machine learning course from Udacity where I was tasked with selecting a model that accurately predicts whether an individual makes more than $50,000. The dataset for this project originates from the UCI Machine Learning Repository. Below is a glimpse of the features…
