Fisher discriminant evaluation FDA an alternate method of discriminant analysis it really is alternative from linear discriminant evaluation, but oftentimes both phrases are used interchangeably. The simplest method is to use mindset 3 above and assume engineering parametric model for densities. Assume category conditional is Gaussian. f kx = frac |Sigma k|^ textbig fracmathbf Sigma k^mathbf must examine frac with frac Note that matlab px denom will also be not noted:f 1x pi 1 with f 0x pi 0 frac |Sigma 1|^ exp fracmathbf Sigma 1^mathbf pi 1 = frac |Sigma 0|^ exp fracmathbf Sigma 0^mathbf pi 0 frac |Sigma|^ exp fracmathbf Sigma^mathbf pi 1 = frac |Sigma|^ exp fracmathbf Sigma^mathbf pi 0 exp fracmathbf Sigma^mathbf pi 1 = exp fracmathbf Sigma^mathbf pi 0 fracmathbf Sigma^mathbf + textpi 1 = fracmathbf Sigma^mathbf + textpi 0 fracmathbf^T Sigma^ mathbf + textpi 1 = 0 frac + textfrac = 0 frac + textfrac = 0 We can see that matlab first pair of phrases is constant, and matlab second pair is linear in x. Therefore, we turn out to be with anything engineering matlab form ax + b = 0. For more about LDA f we calm down assumption 2 i.
