i can’t figure out how to use the outputted weights with the actual nn. how can i instatiate the nn with my trained weights to get my nn output?

As such i dont understand your question, also what dooe Tp and Op signify. gradient descent is the name of the weight update technique, the errors calculated are used in the update of the weights.

One question do perform gradient descent on Ep = 1/2 * S(Tp - Op)2 or E = SEp Where "S" means sum Thank you Jermaine Much clearer. One question do perform gradient descent on
Ep = 1/2 * S(Tp – Op)2

or

E = SEp

Where “S” means sum

Thank you

Jermaine

I need a neural net for my final year project, to interpret shapes read in through a wiimote to enable gesture control. Is there any chance of getting a VS 2005 version?

I used to have shed loads of fun with the other 4/5 members of my team when I played. Without them it was enjoyable, but no where near as much! I have managed to get to grips with much of your code, mainly thanks to all your helpful comments. I have a couple of questions regarding the training set-up - is it possible to read in a separate .csv files for training/testing/validation rather than using the % set-up currently in place? Feel free to shoot me an email :-) Same, although it is only as good as the people you are playing with. I used to have shed loads of fun with the other 4/5 members of my team when I played.

As long as at least one person found it useful, then I've succeeded at what I wanted to do. haha, a bit off topic, man i miss playing competitive CS! I’m really glad you found it useful!

I study Theoretical Neuroscience and Artificial Intelligence as a PhD in England and I found I have very many similar interests to you (I used to run a CS 1.5/1.6 league in the UK called CSGN). I come to the field of neural networks from a biological and psychological background, so the coding is my main obstacle. I mainly work with competitive networks (and Spatial Orientated Maps) for my modelling, so familiarising myself with the code for a back-prop net here was very useful! Keep up the good work :-) Hey Bobby,
