The left most (see NOTE) Input nodes have this problem: The numerical value AND the node internal color*, left of the vertical centerline of the node, do not update when the Teach Lesson button is pressed for an RPROP model. (* you can see a node which is Blue on the LHS and Red on the RHS) You can ...

A few questions about interpreting the displayed nodal values: First, verify what values are being shown: Inputs: Max Lesson values used for Normalization Hiddens: Activation - this is the value output by that node Outputs: Activation - this is the value output by that node (i.e., the predictions) M...

Pattern Error Viewer is a great tool to evaluate error while training. Might it be possible to allow manual scaling of the Y-axis? This would allow Major Grid at Y=0 Major Grid of standard intervals (such as the "1,2,5 log" series: .1, .2, .5, 1, 2, 5, 10, 20, 50, 100...) Method could be u...

NOTE: I'm completely editing this post based on recent test cases. The original contents of this reply will be available at the end for reference purposes. RandomizeNet() generates a set of initial weights based on a random seed each time it is called. This means you cannot reproduce sets of weights...

I know that my model is very sensitive to initialization and during all my learning exercises, I keep getting the same answer which suggests that random number seed is not specified and allowed to default when RandomizeNet() is called. I was hoping that if RandomizeNet() was called repeatedly, the r...

Explored behavior a bit and it looks like this probably isn't the way to do things. What appears to happen is that newly generated nodes connect everything together: Inputs, Hiddens, Outputs. The vast majority of original hiddens had values of 0 so it seems they were removed so to speak. I believe I...

Yes, that did it.

Worked in IE. FYI, did not work in FF. FF couldn't find the files the html used.

OK, so I can study those help files now.

Thanks

Hi Thomas, I tried again, both double clicking on Examples.chm from Explorer and also through Internet Explorer > Open File and got the same result. However, the very first page that comes up in the Help window is: Navigation to the webpage was canceled What you can try: Retype the address. All othe...

When I open the Examples.chm file in the Firefox Browser (also same result in Internet Explorer Browser), I get the Folder tree on the LHS and when I look into any folder, the RHS shows: This program cannot display the webpage Most likely causes: You are not connected to the Internet. The website is...

Just to see what would happen, I tried CC on a custom built network with hidden nodes and connections which were not full layer to layer. First a quick description of my custom network: Imagine two 3-layer networks (In,Hid,Out) where they are combined, in parallel, to produce a single output: the ou...
