neural network design

[tombotley]

Hello,

can anyone give me advice on how to design a neural network that takes greyscale gif input image vectors with 192 elements and classifies them into one of four categories. I have about 60 images to use in total with 15 in each category.

thanks

What class is this for?

Thanks for your response,

my network needs to classify facial images into one of 4 expressions - neutral, happy, sad and suprised.

I have implemented a feed forward backprop network but results not great, unsurprising as I have only been using default settings so far.

I was thinking that I may put my images through a self organising map and then input the results into my ffbp network but dont know how useful this will be.

Cheers
