I just checked and, yes, L2 is indeed the default.

You can use the Display command to examine properties of units. Try it with "-X 2" or "-X 3" to get more detailed info.
You can use the SetType command to set the desired error metric. There are many types available. See: http://nico.nikkostrom.com/doc/
I believe the default is L2, but unfortunately the documentation doesn't specify the default, and I can't look at...

Hello Nikko,
What is the error measure used in the back-prop? since we assume that the output activities are posterior probabilities, literature says the cross entropy measure should be used so the network can map to a Bayesian classifier. Does it use cross entropy by default?

The problem is that net->stream_dir and net->stream_ext are
freed twice. The following patch fixes the problem:

Hi again,
I do not have time to investigate this further right now, but the line that causes the segmentation fault is:
FreeNetWork(net);
Segmentation fault appears in my case only when this line is reached:
FREE(h)
If I remove the FreeNetWork command everything goes fine. I guess all the free commands can be removed if we trust the operating system to free all resources when a...

Hi,
I am using nico version 1.1.1. When I run CResult I get a printout of the results and then segmentation fault. (The command I run is 'CResult -S netname listoffiles').
If I redirect the standard output to file, I get segmentation fault before the program writes into the file, but I guess this depends of buffering somewhere in the redirection.
I checked the code and I saw that some of...

Hi,
I just installed nico-1.1.1.
I noticed that, when running BackProp with the -V option (validation set with classification), the validation error looks ok, while the classification score is always 0.0%. This is an excerpt from my log file:
