Web3.Fisher Linear Discriminant 1 Principal Component Analysis (PCA) One way to deal with the curse of dimensionality is to project data down onto a space of low dimensions, see gure (1). There are a number of di erent techniques for doing this. The most basic method is Principal Component Analysis (PCA) . Figure 1: 1 WebDiscriminant analysis assumes covariance matrices are equivalent. If the assumption is not satisfied, there are several options to consider, including elimination of outliers, data transformation, and use of the separate covariance matrices instead of the pool one normally used in discriminant analysis, i.e. Quadratic method. how do you win gobstones
