In these lec-ture notes, we attempt to demystify some of the fancier properties of multivariate Gaussians that were introduced in the recent factor analysis lecture.
Linear Discriminant Analysis
personal.psu.eduLinear Discriminant Analysis Estimate Gaussian Distributions I In practice, we need to estimate the Gaussian distribution. I ˆπ k = N k/N, where N k is the number of class-k samples. I µˆ k = P g i=k x (i)/N k. I Σ =ˆ P K k=1 P g i=k (x (i) −µˆ k)(x(i) −µˆ k)T/(N −K). I Note that x(i) denotes the ith sample vector. Jia Li http ...
