Hi Pascal, First of all, thanks for all your interest in NuPIC and HTM. I can tell you're really excited about this stuff and I love that kind of energy in our community!
Taurus was established as a scalar anomaly detection system, not a geospatial anomaly detection system. Because all of its data displays are tuned towards scalar charts and graphs, I'm not sure how much help it will be. This leads me to the next point.... HTM Engine was also build for scalar anomaly detection, not geospatial :(. The pretty much means that you will not be able to pass HTM Engine "timestamp / lat / long" events. It currently only works for "timestamp / scalar value" input. But, this doesn't mean things are hopeless. IMO there are many great opportunities to improve the interface of HTM Engine. There are several things I wish that it did: - prediction - multiple input fields - geospatial encoding Just to name a few. If these are features that others want to see in HTM engine, please file a ticket so we can prioritize our work: https://github.com/numenta/numenta-apps/issues/new Regards, --------- Matt Taylor OS Community Flag-Bearer Numenta On Mon, Aug 3, 2015 at 2:14 PM, Pascal Weinberger <[email protected]> wrote: > Hey All! > > For the htmengine infrastructure for nostradamIQ, I was trying to understand > Taurus and use it as a template to build on, as it already has multiple > metrics (stock and twitter) for multiple classes (companies).
