Matlab crashes after training several RFs #24

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Hi all, 

I'm using the RF toolbox applied to supervised classification with 
active-learning (AL). A feature of this method, is that a classifier get 
iteratively retrained, in this case a RF classifier. When it reach something 
like 20.000 retrains, Matlab crashes and display the attach image.

I tested on windows 7 running Matlab 2008b and 2011a, obtaining a similar 
response.

Here's the Error Message:

This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.

If it is an official MathWorks function, please
follow these steps to report this problem to The MathWorks so we
have the best chance of correcting it:

The next time MATLAB is launched under typical usage, a dialog box will
open to help you send the error log to The MathWorks. Alternatively, you
can send an e-mail to segv@mathworks.com with the following file attached:
    AppData\Local\Temp\matlab_crash_dump.4280

If the problem is reproducible, please submit a Service Request via:
    http://www.mathworks.com/support/contact_us/ts/help_request_1.html

A technical support engineer might contact you with further information.

Thank you for your help. MATLAB may attempt to recover, but even if recovery 
appears successful,
we recommend that you save your workspace and restart MATLAB as soon as 
possible.

I appreciate any comments.

Regards
