Gaussian Discriminant Analysis an example of Generative Learning Algorithms Generative Learning Algorithms: In Linear Regression and Logistic Regression both we modelled conditional distribution of y given x, as follow.

“It is more important to have beauty in one’s equations than to have them fit experiment…” — Paul Dirac This is also know as ‘Classification’. This is used in many scenarios where we want to categories input in predefined classes. For ex. tag email as spam/non spam, predict the age…

“An approximate answer to the right problem is worth a good deal more than an exact answer to an approximate problem.” — John Tukey linear regression is a linear approach for modeling the relationship between a scalar dependent variable y and one or more or independent variables denoted X. Unlike…

Calculus has its own limits :) Definition: matrix calculus is a specialised notation for doing multivariable calculus. It collects the various partial derivatives of a single function with respect to many variables, and/or of a multivariate function with respect to a single variable, into vectors and matrices that can be…
