Well, "Fisher's LDA" is simply LDA with K=2. When doing classification within such LDA Fisher invented his own formulas to do classification. These formulas can work also for K>2. His method of classification is hardly used nowadays because Bayes approach is more general. Mar 6, 2014 at 5:43. 1.

The terms Fisher's linear discriminant and LDA are often used interchangeably, although Fisher's original article actually describes a slightly different discriminant, which does not make some of the assumptions of LDA such as normally distributed classes or equal class covariances. Suppose two classes of observations have means and covariances . Then the li…
