I'm completely new to nupic. However I have a few decades experience in software AI and related fields. What I'm asking is if Nupic is something I should look into. I've read "On Intelligence" and some of the web page but the Nupic software seems to be a tiny subset of that.
The subject area is Morse Code recognition. In the simple case of machine generated Morse Code with no noise this is a very easy problem. But in the real world the timing is variable,there is VERY high levels of noise and likely several conversations all going on at once. My task is about like going into a noisy bar where many people are talking loud and attempting to simultaneously transcribe every conversation. Ok, it's easier because Morse is almost already digital and the data rate is only as fast as human hand can push a single contact key. I can reduce the date rate by time tagging the transitions when a tone changes. This reduces the data from the 48,000 sample per second audio to about 100 or so tokens per second. But I would MUCH prefer to use a learning algorithm to pick these transition out of the noise. Best if I could input the audio directly. (Yes I saw the audio example) The problem is very much like speech. It is hierarchical with "elements" (dots , dashes, spaces,..) making up letters and letters making words and words making up very stylized phrases. Also like speech humans are "sloppy" and slur it and change their speed and talk over top of one another. My plan currently to using well known speech recognition algorithms but hand tuned to Morse Code. What I'm wondering after reading On Intelligence is if NuPic is up to the task. I know I'd have to build in my own hierarchy but the levels are so well defined. The goal is to recover the letters that are sent using context to "fill in the gaps" but NuPic does not seem like something you train and I don't see how it could ever recover the letters and words. Am I correct to assume CLA might work but NuPic is not up to this task? I'd be happy if I were wrong. -- Chris Albertson Redondo Beach, California
