Getting number of data points for training, validation and testing of neural network; showing the training and testing data of neural networks?

I have analyzed the experiment data using DA, DD, SPEED, FEED as 'Input' and Thrust as 'target' by transposing the data given in Microsoft excel file using NNTOOL. I also have Included the related pictures regarding the network. Please tell me how to get number of data points for training, validation and testing of neural network;

Answer 1

[Neil Guertin]

nntool is an older tool and is not recommended. Use nnstart instead. From there you can get to the Neural Fitting app which has options for setting training, validation, and testing percentages, and will walk you through the rest of the neural network creation process.

how do know which are the training and testing data in ANN ?

[Neil Guertin]

The data will be split randomly into training, validation, and testing sets based on the percentages provided.

How can I show the training and testing data in Microsoft excel format or in the text format?

[Greg Heath]

 [ net tr y e ] = train(net,x,t);

 % y=net(x); e = t-y;

% To find the trn/val/tst indices view the training record tr, via

 tr = tr  % No semicolon

Hope this helps
