Difference between Variance and Covariance

Variance is the measure of, the spread between numbers, in a given data set. In other words, it means, how far each number in the data set is, from the mean of this data set. 2. Covariance is the measure of, the directional relationship between, two random variables. In other words, covariance measures, how much, … Continue reading Difference between Variance and Covariance

Difference Between Batch, Mini-Batch and Stochastic Gradient Descent

Gradient Descent is one the key algorithm used in Machine Learning. While training machine learning model, we require an algorithm to minimize the value of loss function. Gradient Descent is one of the optimization algorithm , that is used to minimize the loss. There are mainly three types of Gradient Descent algorithm1. Batch Gradient DescentBatch … Continue reading Difference Between Batch, Mini-Batch and Stochastic Gradient Descent
