Perhaps I'm misunderstanding confluence.py, but I thought it was taking the last updated value of the slower stream, i.e. the input becomes,
t1 A1 B1 t2 A2 B1 t3 A3 B1 t4 A4 B2 t5 A5 B2 t6 A6 B2 t7 A7 B3 etc. Whereas what I'm thinking of is, t1 A1 B1 t2 A2 ignore t3 A3 ignore t4 A4 B2 t5 A5 ignore t6 A6 ignore t7 A7 B3 etc. Phil. ________________________________ From: nupic <[email protected]> on behalf of Matthew Taylor <[email protected]> Sent: Wednesday, 6 April 2016 7:32 PM To: [email protected] Subject: Re: Multi-input and multi-level models Yes, that is what menorah does in the "Confluence" class.

However, is it possible to input multiple series where each is dependent on a different time? i.e. signal A arrives every 1 minute, but signal B arrives every 5 minutes, etc?

In terms of the hotgym example, I think of that as really being 1 time series input rather than multiple inputs. One thing I need is to be able to input multiple time series'. In particular, inputs that arrive at different time intervals. (The inputs can't be handled by aligning them with just one time vector - each input needs it's own time vector.) Thanks Phil. ________________________________ From: nupic <[email protected]<mailto:[email protected]>> on behalf of Marcus Lewis <[email protected]<mailto:[email protected]>> Sent: Monday, 28 March 2016 5:49 AM To: [email protected]<mailto:[email protected]> Subject: Re: Multi-input and multi-level models Hi Phil, Multiple inputs are pretty easy with the OPF (i.e. the CLAModel). For example, hotgym<https://github.com/numenta/nupic/blob/master/examples/opf/clients/hotgym/simple/model_params.py#L66> uses the timestamp and the current power consumption. For multi-level models, you'll probably want to use the Network API. Subutai gave a recent talk: https://www.youtube.com/watch?v=g9yS9zFt3dM . Here's a demo that uses multiple levels: https://github.com/numenta/nupic/blob/master/examples/network/hierarchy_network_demo.py Strictly speaking, from the Network API's perspective, the CLAModel only has one input, since it concatenates<https://github.com/numenta/nupic/blob/master/src/nupic/frameworks/opf/clamodel.py#L1108> the encodings via a MultiEncoder, but that's just an implementation detail. I recently created a demo that puts multiple inputs into a Network: https://github.com/numenta/nupic/blob/master/examples/network/core_encoders_demo.py Hope that helps!

With multiple inputs, the nearest example I can find is the NY Taxi example. However the technical paper I have indicates that the 3 inputs are aggregated into one input (via competitive polling) before being fed into the model. Can anyone tell me if it possible to have multiple inputs? Or do multiple inputs have to be processed into one input as per that example? I can't find the code for the NY taxi example (in the NuPIC GitHub repository). Is it available, and if so where? Also, is it possible to develop multi-level models? If anyone can point me at any technical description of such models, or a code example, I'd appreciate it. thanks Phil.
