Since it is not always possible to study the entire population, we need to rely on sampling to acquire a segment of the population to perform an experiment. It is also essential to make sure that […]

K-means clustering is one of the simplest unsupervised learning algorithms that solve the well known clustering problem. Before we venture into K-means, let’s first understand what clustering is? What is clustering? The idea behind clustering is […]

Continue readingMore Tag## Regression Evaluation Metrics

Once we build our regression model, how can we measure the goodness of fit? We have various regression evaluation metrics to measure how well our model fits the data. In this article, we will see some […]

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 […]

Continue readingMore Tag## Performance Measures for Classification

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 […]

INTRODUCTION: When we have deep neural networks, the biggest problem is overfitting. We can say a neural network overfits when it has excellent performance in the training data and has a poor performance in unseen data. […]
