Author Topic: BPTT SRN does not recognize sequence - help

I am trying to make a BPTT SRN recognize a given sequence of three letters ("abc") within random letter sequences. The task is to simply decide whether the sequence exists within a sequence or not.

The problem is that the network simply does not fit the inputs with the desired targets - it does not learn. In some way it does divide the input set into two categories, but it seems only to recognize if the last letter of a sequence is a "c", no matter the previous letter(s) - so, it seems not to analyze the sequence, but only its end. (But it doesn't do that completely consequentially - it makes errors anyway.

If anyone has any ideas about what might be wrong, I will be very grateful for any suggestions.

I'm working in LENS, btw.
