Machine Learning 101: Implementing Logistic Regression and LDA from scratch
What a better way to really understand something than doing it yourself? Here, along with two other teammates, we had the opportunity to implement two famous classic machine learning algorithms: Logistic Regression and LDA, examples of discriminative and generative algorithms, respectively. We also had the opportunity to explore standard ML techniques such as data cleaning, feature engineering, k-fold cross-validation implementation, CV-Grid search, and visualizations.
