WebWasserstein Discriminant Analysis (WDA) [13] is a supervised linear dimensionality reduction tech-nique that generalizes the classical Fisher Discriminant Analysis (FDA) [16] using the optimal trans-port distances [41]. Many existing works [44,29,11,4] have addressed the issue that FDA only considers global information. 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…
