memory problem

3 March 2008

when trying to load the sound list over the weekend the computer ran out of memory.

sound

worked on looking back into my sound stuff today, transferring functions over to my new network program, making improvements and completely rewriting some things so that they can be used easier. while looking into my old program i saw that i actually hadn’t been pitchshifting/detuning the sound files (i only did that with generated sounds), so i wrote a function that can pitchshift the files within mathematica. i also greatly improved the random training pattern generation function… now it will always output at least one instrument playing one note (but now that i think about it there should be at least a small chance that there will be no instrument playing) and instruments can be specified to be polyphonic or not. another idea i might try to implement in the future is adding random noise to the training patterns. the file is sndnn01.nb and it is backed up on euclid.

also, the three other computers in here have been set up to not reset, so in the future i’ll be able to train overnight on four machines.

at home and at school

at home: that one candidate finally finished training but didn’t do anything at all to help the network’s error. i stopped network training because it didn’t seem to be going anywhere.

at school: the good news is that the changes made worked and the computer didn’t reset overnight. the bad new is that mathematica had an error. “No more memory available. Mathematica kernel has shut down. Try quitting other applications and then retry.” since the kernel shut down, the weights at the time of the error can not be restored.
