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

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 papers ...

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 ...

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 to ...

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 ...

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,

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 ...
