Hi im reading "C++ Neural Networks and Fuzzy Logic by Valluru B. Rao", anyway in one section, i don't get how they are getting this answer for the product of the matrix;
...from the book
Quote:
First, we notice that the binary to bipolar mapping of A = (1, 0, 1, 0) gives the vector (1, –1, 1, –1).
Then we take the transpose, and multiply, the way matrices are multiplied, and we see the following:
1 [1 -1 1 -1] 1 -1 1 -1
1 = -1 1 -1 1
1 1 -1 1 -1
1 -1 1 -1 1
to me it looks like the answer should be:
1 -1 1 -1
1 -1 1 -1
1 -1 1 -1
1 -1 1 -1
I don't get it. Whats going on?
Thanks
