Decision trees are one of the most powerful and widely used supervised models that can either perform regression or classification. In this tutorial, we’ll concentrate only on the classification setting. A decision tree consists of rules […]

KNN from Scratch
The K-Nearest Neighbor(KNN) classifier is one of the easiest classification methods to understand and is one of the most basic classification models available. KNN is a non-parametric method which classifies based on the distance to the […]

INTRODUCTION: In the last part, we see what a confusion matrix is and some other metrics like TPR, TNR, FPR, and FNR, which are based on the confusion matrix. In this post, we will see about […]

Why do we need performance measures? Why do we need performance measures at all? After we developed our classification model, we need to asses the performance of the model. Obviously, we can use accuracy as a […]
