did some overnight training using sigmoid outputs with the four-note glockenspiel samples again, and it still is missing that first note… i think the problem might come from training using intensity rather than rms value for the sounds. when i switched seems to be when that first note went missing. i’m currently briefly training the network again with a larger multiplier, so maybe that first note will get noticed this time.
also, i made the training work so that after every 1000 training patterns are applied the network checks its “error” and adds the value to a list. this way i can make a listplot to see how the error evolves over time and at what point further training doesn’t have a significant effect. here are the results from last night’s overnight training:
