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. […]

Why do we need activation functions? We use activation function to introduce non-linearity into the neural network. Activation functions convert independent variables of near infinite range into simple probabilities between 0 and 1. Now the question […]

Principal Component Analysis is an unsupervised dimensionality reduction technique, which is extensively used in machine learning. It helps us to alleviate the problem of the curse of dimensionality by reducing the dimension of the data. PCA […]

INTRODUCTION to T – SNE: T-SNE is a non-linear dimensionality reduction technique used to visualize high-dimensional data in two or more dimensions. Unlike PCA which preserves only the global structure of the data T-SNE preserves both the local […]

INTRODUCTION: For algorithms like the k-nearest neighbor and k-means, it is essential to measure the distance between the data points. In KNN we calculate the distance between points to find the nearest neighbor, and in K-Means […]

What is machine learning? So what is machine learning anyway? ML is a subdomain or a subfield of artificial intelligence. In the last few years, machine learning has become one of the most important branches of […]
