MemBrain Neural Network Editor + Simulator User Forum

The Version History is awesome.

Release Dates would allow "improvements over the past 5 years" to be determined.

THanks

I have been away from using Membrain for at least 3 years and was wondering what new features it has.

Thanks
Tom

I will try to find the reference, but I believe the derivative they use is a "combination of" the activation function AND the CEE. NOTE: Just thinking: If it is d(E)/dw then the activation is involved since it is required to calculate E (or CEE in our case.) It is made clear in a number of...

QUESTION: If user specified error function, aren't user specified partial derivatives of the error function also required for back-propagation ? First, it is difficult to find the actual formula for this error type. The one that I like the best is how MathWorks tells users how to user define it sin...

The % change results in a "shotgun blast diameter" that varies in each weight dimension by the size of the weight. If 2 weights, would get an ellipse in xy plane or elipsoid in xyz plane. If we want a spheroid in xyz plane, need a constant fixed delta applied to weights. Should be simple t...

MORE ON THIS: Appears that attempting to print Header is a problem. If Header omitted, have found 2 behaviors: PRINT From Preview: Here, only one page can be printed. Any subsequent attempt get different error of stringlist out of bounds. So you have to exit program and execute program to print anot...

We have a small office network with printers connecte4d to various PCs in that network. EIDT: Problem encountered when printing from an XPpro machine to a Vista machine with USB HP 5500 printer. I tried print script from the PSPad editor and got a "PSPad.exe - Application Error" in the win...

I can see how to Create a Link between two different nodes: void ConnectInputToOutput() however, I cannot see how to select the Link so I can get at its Properties. Maybe the commands: void SelectLinksFromExtra() and void SelectLinksToExtra() ? Could find no examples of Link editing in NetEditor cla...

I'm trying to do my own custom Randomization and I cannot see any way to do this. All the ways I have found require mouse selection.

Perhaps there is a way to modify the .mbn file?

Thanks in advance,
Tom

Both Momentum and RPROP have to deal with not getting stuck in local minima. These methods do not have a lot of finesse in this area. There are a number of things that can be done with randomization to jump out of local minima traps such as applying a dither reconnoiter when in the grasp of a local ...
