David,
I’ve been using HTM.java for awhile and have a few questions:
1.) There is a “LEARN” parameter that I presume is for the
SpatialPooler. Right? Is there one for the TemporalPooler in the case where I
want to change TM settings programmatically?
2.) I’ve created a network using the fluent style where the Classifier
is added as a parameter. Is there away to change the settings on the Classifier
once it’s been added to the network? I’d like to train the TM prior to sending
data to the classifier by disabling the Classifier and enable it
programmatically, say at a given record count.
Thanks, for the update. Appreciate all the hard work.
-Phil
