#1

Is there any mode to import data for the network not in csv file? For example query on db?

Just letting anyone who may be interested in the answer to this, that the question was answered in the Gitter channel earlier.

Here is the conversation for your convenience:

[quote]Hi @dinvi Welcome! In HTM.Java, you can “manually” insert data into an HTM network, so you would have to do a query and then read from that query in your own code - inserting the data as seen here: https://github.com/numenta/htm.java/wiki/Sensors#observablesensor-with-persistenceapi
But at the moment, there is no way to “directly” point to a DB and have it load the data. If you have a “different” format, you will need to convert the data to a “CSV” format yourself - on-the-fly (line by line as you enter the data), or by pre-processing it before hand.[/quote]

If you check out Matt’s example sine predictor project (https://github.com/rhyolight/nupic.examples), there’s code in there that could be re-tooled to import directly from a web-service, DB or any other source. Basically, the code just iterates over rows found in the CSV file, and parses them into variables, before calling NuPIC functions to bring them into the model.
