A.14 MLP Sets

The MLPSets.xls file contains 26 pairs of points (Xl, X2) and 2-class classification
columns, exemplifying the following situations:

C1 linearly separable classes with one perceptron
C2 XOR-like classes, separable with a two-layer MLP
C3 Separable with a three-layer MLP

The Norm2c2d.xl.s file contains two sets with n=50 points of 2-dimensional
distributions with the same covariance matrix. The distributions were generated by
linear transformation of N(0,1), using the following transformation matrix:

The dataset is as follows:

Set 1: columns nl 1 and 1112; Mean=[l I]'
Set 2: columns n21 and 1122; Mean=[3 41'
Covariance = :::;I ; ~nverse covariance =

The distribution parameters can be easily changed, altering the values in the
spreadsheet column m, C containing the means and the coefficients of matrix A.
