Basics of Probability and Statistics 1. Sample Variance vs Population Variance The formula to calculate population variance is: `sigma ^2 = (sum (x_i - mu_x ) ^2)/N` The formula to calculate sample variance is: `s^2 = (sum (x_i - mu_x ) ^2)/(N-1)` The difference between the two formulas is: When we calculate population…

Basics of ML & AL   1. Business Moments:   2. Significance of expected value when simple mean (Sum of all observations/number of observations) is already in place:       It is true that simple mean is sufficient enough for having an idea about the data by computing with it's formula (Sum…

Supervised Learning  Prediction   1. Gradient Descent  The gradient descent in python using mean square error as loss function on the following data set: x = [0,1,2,3,4] y = [1,2,3,4,5]   Theory: `J = (1/n) sum(y(i) - (mx(i) + b))^2` x(i) are the input m and b are the weights  mx(i)+b is the predicted…

Supervised Learning Classification   1. KNN on Surface Defects in Stainless Steel Plates K-Nearest Neighbors is a supervised machine learning algorithm that classifies a data point based on how its neighbors are classified. It classifies new cases based on feature similarity measures. KNN algorithm K in the KNN algorithm…

Supervised Learning Classification   1. Neural Network     Neural networks, also known as artificial neural networks (ANNs) or simulated neural networks (SNNs), are a subset of machine learning and are at the heart of deep learning algorithms. Their name and structure are inspired by the human brain, mimicking…

Unsupervised Learning  Kmeans   1. Calculating Similarity id Data is Categorical in Nature        The simplest way to find similarity between two categorical attributes is to assign a similarity of 1 if the values are identical and similarity of 0 if the values are not identical.…
