Decision Boundary for a Series of Machine Learning Models

I train a series of Machine Learning models using the iris dataset, construct synthetic data from the extreme points within the data and test a number of Machine Learning models in order to draw the decision boundaries from which the models make predictions in a 2D space, which is useful for illustrative purposes and understanding on how different Machine Learning models make predictions.

Machine Learning (XGBoost) Time-Series Classification Trading Strategy

I construct a series of time-series features from the literature and apply a novel XGBoost model to predict the next days price of a number of assets. The concept is simple and can be expanded to many variables, incorporate many assets and be applied to different Machine Learning models.

Series of Hackerrank Competitions

I show my solutions to a few Hackerrank competitions/problems I had completed and discuss the models and solutions.
