My input is a 127x108 matrix of 108 attributes (the features) of 127 training dataset. the features are from image zoning 3x3. And then
My target is a 127x36 (row x column) matrix, column indicate what letter it is. (i.e : 0, 1, 2, 3, 4, 5, 6, 7, a, b, c,... i, I, j, k, l,... u, U, v,.. z). Total are 36 characters.
Thanks before.

i've just tried to train my data set, but the cross-entropy and percent error is so far to reach 0. i've tried to set the hidden layers value to 10, 30, 35. but havn't gotten any proper result.
