Hi all,

I am Master degree student, working on time series prediction. I am looking for some software to estimate lyapunov exponent using Grassberger-Proccacia Algorithm. I would be happy to get any light here...

Thanks,

Help with Designing a Neural Net

Hi,

I am very new to the area of neural networks and was hoping somebody would be able to give me possible suggestions on how to design the neural network for my particular problem.

Any sort of help would be greatly appreciated.

1. I have a large continuous action and state space.
2. My goal is to find a good action to take while in a particular state.
3. However, I do not have any training data. I do however, get to know the cost of taking an action in a particular state after of course, taking the action.
4. Hence, I was thinking of using this cost somehow to train the net to choose actions when in a state. I could perhaps, train the net by adjusting the weights appropriately, when the cost goes up or down from the previous time period.

Most of the research seems to be for supervised learning with training data. However, I have not been able to find papers that want the neural network to learn a mapping from state to action in a continuous and large action space.

Any suggestions?
Thanks
Annapurna
Incorrect predictions

We can export incorrect predictions but
exactly what are we looking for?
Is it a particular field with the same or very similiar values?
Is is a combination of fields that look the same?
Horseracing is not entirely honest and so predictions
will never be a 100% but where should we draw the line?
Stop training when the error rate is less than ?? % ?
Export the incorrect predictions to Excel and then sort and subtotal?
Any thoughts or advice most appreciated.
Regards
Ray
arrays of nets

after my previous post, a thought occurred to me - does the dll require that a '.net' file be closed before another is opened? This could (I think) explain it - the program will be spending most of its time opening and closing the '.net' files, even though they are on a memory disk. If this is the case, is there any way round it?
arrays of nets systems

I am using the SDK with Delphi and am updating items using an array of neural nets.Everything works OK but I have a problem with the amount of time it takes - eg if I have an array of 1, update using the net takes approx 3 minutes, updating a second on its own takes approx 3 minutes, put the two together takes 3 hours 8 minutes, but produces the correct results. On profiling, the results on calling the DLL are (processing share): 1)array of one item=6.32; 2) array of two items for same time=92.98.
I have tried everything to speed up (dynamic & static loading, different procedures) but nothing seems to make any difference.
I am hoping to end up with an array of several items but cannot hope that this will work correctly as it stands.
I can't help thinking it must be something obvious, but I have spent about a week experimenting without any progress.
Any ideas?
