Principal Component Analysis (PCA) Program in Python from Scratch

Principal Component Analysis (PCA) is a machine learning algorithm for dimensionality reduction. It uses matrix operations from statistics and algebra to find the dimensions that contribute the most to the variance of the data. Hence, reducing the training time. For…

Naive Bayes Classification Program in Python from Scratch

Naive Bayes classifiers are a family of “probabilistic classifiers” based on Bayes’ theorem with strong independence between the features. They are among the simplest Bayesian network models and are capable of achieving high accuracy levels. Bayes theorem states mathematically as:P(A|B) = ( P(B|A) * P(A) )/…
