Irwan,

Swarming gets you the best parameters for a data set to create an OPF
Model. You can swarm over as little or as much data as you wish. It's
usually better to swarm over more data, but there is a point of
diminishing returns. Once you have model params, you can create an OPF
Model and immediately start feeding it data.  A new Model is just like
a section of blank neocortex, it has no memories. Just because it was
created with model params created by swarming over the data doesn't
mean this new model knows any of the patterns within the data, so
there will still be a period of time where the model returns high
anomaly scores and bad predictions while it learns the patterns in the
data.

But all the time it sees rows of data, the model is learning. At the
beginning, it knows nothing, it was just configured to have decent
parameters for the data you pass it because you swarmed to get those
best params. There's really not a "training set" and a real data set
for NuPIC. You just feed it data and it gets better.

The sine wave example is not the best one for this, because the data
is generated -- not real world data. You might want to look at a more
realistic example I just finished:
