They are all different things. ANN, HMM, etc... this is machine learning, reasoning algorithms, and so forth.

As far as I know Pd has no basic set of machine learning techs, such as openCV has.

I'm not a huge fan of replicating tools, so I would take existing external tools and just interface with them, but since you point out that you are not happy with them, my suggestion is useless. Anyway two pointers:

- http://sourceforge.net/projects/cvhmm/ (HMM)
- http://opencv.willowgarage.com/documentation/cpp/neural_networks.html (NN)

Thanks, Marco. I have been using OSC communications with other software, but I'm far from satisfied. I'll try ANN, thought.

I am actually interested in working with Hidden Markov Models (and machine learning in general) and some filters for computer vision. Can I work with those using ANN?

Best,

Leandro

Hey,

I've been using the ANN library.
I'm not sure it's still updated nor mantained these days, but it does work well for my purpose.

That is, I've been using it to make my instrument (the Xth Sense [1]) detect a performer's muscle states throughout a piece by using 1 sensor only; then, labelling different states, such as still, motion, fast motion, slow motion. It's a basic implementation but useful to create a sensing timeline that changes with the performer behaviours, rather than with fixed time cues.

Surely, there is much more to AI which cannot be presently done in Pd, at the best of my knowledge, I might be wrong though.
Ben (Bogart) is our guy in this area.

What are you using Ben?

Hi all

I have been wondering... Is there any AI implementation for PD? What have you been using for it?

Best

Leandro
