MATLAB: Manual Calculation of Neural Networks

Deep Learning Toolboxneural networks

Is there a way to manually follow the equations on a neural network that has been trained and tested using the ANN toolbox?

I want to see if I can follow the equations and see where my app that I've created that replicates the values and calculations of my trained network is differing.

Thanks,

If the classes are not mutually exclusive (e.g., tall, dark, handsome) logsig is an appropriate output transfer function for approximating input-conditional posterior probabilities.

For mutually exclusive classes, the probabilities sum to one. The unit-sum softmax is appropriate.

MATLAB: Can target vector of neural network have sum of columns >1

No! Target columns should be columns of eye(56);

 truclassindices = vec2ind(target);
 target          = ind2vec(truclassindices);
 ...
 output          = net(input);
 estclassindices = vec2ind(output);

Hope this helps
