and the decision boundaries are given by

P( ω 1 |m )>P( ω 1 |m ) lnP( ω 1 |m )>lnP( ω 1 |m ) lnP( ω 1 |m )+lnP( ω 1 )>lnP( ω 1 |m )+lnP( ω 1 ),( 3.50 )

The decision boundaries are hyperplanes that are perpendicular to the connection lines between the expectation. If the a priori probabilities of the classes are equal, i.e., ln P( ω i ) P( ω j ) =0, then the hyperplanes lie at the center points between the expectation vectors. If the a priori ...
