This is Part two implementing Naive Bayes Classifier from scratch in Python; A single model for both Categorical & Numeric data. Check Part one for a refresher where I discuss theory and application intuitively.
We’ll also get introduced to approaching Machine Learning Imbalanced Binary Classification problem; Discussing topics like: Feature Engineering, K Fold Cross Validation & Model Evaluation using several tools & metrics (Precision, Recall. Accuracy, Classification Report and Confusion Matrix).
At the very end, we will explain the code used to generate the Jupyter Notebook; This includes Python Class/Object, Data Class, Slicing, Loops & much more.
