how to train a bottleneck neural network with code

I have created bottleneck network using makebottle.m from matlab help .Please help us to train this network using backpropagation technique

Answer 1

[Greg Heath]

1. What Toolbox is makebottle in?

>> help makebottle

makebottle not found.

2. The traditional definition of a bottleneck network is a regression network (e.g., the obsolete newfit or the current fitnet) with

a. node topology:        I-H-O = I-H-I 

b. training data:        target = input

c. bottleneck geometry:  H << I 

 help fitnet     % regression/curve-fitting
 doc fitnet

For more training examples, search using

 greg fitnet Ntrials

Hope this helps.

Thank you for formally accepting my answer
