Hi,
I have a matrix multiplication. First matrix is input_of_hidden_layer2 second matrix is error_of_hidden_layer2.
Before multiplication I check the number of NAn values in the matrixes as below:
result1 = sum(isnan(input_of_hidden_layer2(:)));
result2 = sum(isnan(error_of_hidden_layer2(:)));
disp("result1 " + result1);
disp("result2 " + result2);
I also print the matrix values.
This is the multiplication
delta2 = vpa(((input_of_hidden_layer2>0).*error_of_hidden_layer2),150);
The resulting matrix delta2 is a (30,1) matrix and contains 14 NaN values. There is no Inf value, there is no division. I think this is nonsense. Please help me to understand and fix this problem.
I attached the matrix values in a separate file for you to check.
Best Regards,
Ferda
