Is convolutional network is NuPIC's category then. How about preprocessing of images as linking the same digits via elastic temporal transformations - it must be perfect in HTM's terms ? I'm not sure it is allowed though..

Numenta has always been criticized[1] for not providing comparisons between NuPIC and other ML approaches by posting the results for standard data sets and taking part in competitions. It would be great if we could mobilize motivated members of the community to tackle things like this. I've created a wiki[2] with a list of common data sets used for ML comparisons, as well as competitions. If anyone is willing to work with one of these data sets, I would be happy to publicize your work as well as I can. The more we can interact with the existing ML community, the more participation we'll get from them.

I ended up focusing my time on preparing the Pilot framework for the hackathon. Either way, there's not much time left in the competition now.

I was thinking that we could start simply, by just feeding in the stream of solar energy readings to the CLA sequentially. This will allow us to see how well it does at predicting solar energy from just the temporal sequence, and the time of day, day of week, etc. In parallel, someone else can learn to extract what we need from the GEFS weather data, correlating the weather variables with each solar energy reading time. We can build a CSV file of all the variables together, and run a swarm. How does this approach sound? I can volunteer to set up the project and start feeding the solar energy with temporal information to the CLA. Whoever wants to help is welcome to. Anyone up for massaging the GEFS data as described above? Thanks,Chetan P.S. We still need a team name!
