... This sounds like an interesting task and a useful area to explore. It makes sense that as the "path" gets longer the ANN performs less and less well. I'm...
... You are cetainly correct that in the biological case, a one-bit error ruins the return path, since it no longer takes the animal home. And also, as you...
Hello All, I stumbled onto NEAT a short time ago, and I think its an amazing piece of work - I'm not an expert on ANN's / Genetic Algorithms by any means, but...
Hi Mitchell, All, I've intended to look into tasks requiring memory for some time now, and it should be really easy to throw together soem code for SharpNEAT...
Hi Mike, ... Currently there is no setting to do this so you would have to modify the code. One way would be to add the fitness threshold as a property on ...
... No, I started out with this one. But it's prolly a good idea to try the simpler one first. I'm not sure why I skipped that step. In my latest version I...

First Off, thanks to everyone who replied to my questions, its good to see a newbie-friendly discussion group :) I have a lot of reading to do. In response to...
Hey everyone, I wanted to post a quick message about what I've been up to recently. As some of you know, I started as an assistant professor at UCF 6 months...

All, Just in case anyone might be interested, I have a paper on some of my work for a hardware accelerator for NEAT. It's available at the following url: ...
All, For those that remember, I originally got interested in NEAT in order to do image enlargement. The primary thing that has stood in the way of progress, ...
I just found out that the version that was up of my tech report on CPPNs had been checked by a buggy spellchecker that let through a lot of typos. I never...
I cannot see any files in the CVS folder on SourceForge for SharpNEAT. I know that the source is included in the package for SharpNEAT 1.04 but is there also...
I have noticed that my best fitness sometimes declines. While I can sort of understand this if I have enabled 'pruning', it also occurs even when I disable...
... Ok two points to start with: 1) SharpNEAT will always preserve the species with the best genome, even if it has reached the drop-off age. 2) Pruning isn't...
Hi Peter, ... Sorry no. I may make the source available via CVS in the future, but right now it's an archive file only, plus there is a text file that ...
Thank you for your detailed reply. I am very impressed with SharpNEAT. Thanks for sharing it. I do not understand how I am losing the most fit. My evaluation...
I did some further testing and I can easily replicate SharpNEAT losing the most fit individual. To replicate: 1) Choose the Multiplication experiment 2) click...
... That my not be a red herring. I'm not sure exactly how it might happen unless there was a bug in the code, but I can see where re-speciating an individual...
Hi Ken, I just finished reading your paper. Cool stuff. It's exciting to see you expand NEAT in such a novel way. I have a few comments and questions. 1) I...
Hi Peter, Ok I was able to recreate the problem using the example you gave. John, yes it does seem to be a problem caused by the re-speciation and the example...

Terrific! Thanks Colin. I am running with the new code now and will be able to confirm whether it fixes my original issue after running for a few hours. As I...
Philip, thank you or your comments. It's really helpful to hear thoughts like yours at this early stage of research. I'll try to address some of your...
Hi John, I'll try to answer a couple of your questions below. By the way, I had a student in my class who used NEAT for image enlargement (he called it "image...
All, A short question... It seems to be accepted that regularisation methods (weight decay etc) can be beneficial from a generalisation perspective in ANNs....
... Correct. Based on what I have read, an appropriate subset is 9x9 pixels at a time. As a general question, in what way will NEAT inspired interpolation ......
