RE: Reset field in input data

[Kalle Tammemäe]

Thanks! Helpful reference indeed.

I have run swarms with and without reset data column. Resulting empty “brains” 
were then trained using the same data, but the anomaly likelihood difference 
was so small that caused doubt how well or if at all is reset taken into 
account. Probably the parameters of “brains” don’t differ much.
Only after that I experimented with modified swarming description which yielded 
unsupported type error.
I have expected reset being valuable during learning phase. E.g. observing 
someone exercising it helps when cyclic exercise start (and end) can be clearly 
distinguished.
Well, let’s see does it help when I replace binary reset with string type 
signal.

Hi Kalle,

Resets are taken into account during swarms, and you should NOT add them to the 
"includedFields" section of the swarming description. The error you see is 
unrelated, however: https://github.com/numenta/nupic/issues/1775

Hi,

I would also appreciate a little help.
I’m experimenting with repetitive signals (rehabilitation) where it is possible 
to define start/reset of the typical exercising cycle.
Sounds reasonable to this information to facilitate HTM training.

As an example, the first rows of .csv file are following:
sens1,sens2,sens3,sens4,sens5,sens6,sens7,sens8,sens9,reset
int,int,int,int,int,int,int,int,int,bool
,,,,,,,,,R
-593,-3910,-1066,55,13,33,-892,-1554,686,0
<snip>

It is not clear does swarming “see” and use reset field automatically. Should 
it be described in swarm_description.py file?
Still, trying to do that i.e. adding section to includedFiels after input 
signal sections:
    {
      "fieldName": "reset",
      "fieldType": "bool"
    }

…does give an error on swarming:
    claDescriptionTemplateFile = options.claDescriptionTemplateFile)
  File 
"/home/kalle/.local/lib/python2.7/site-packages/nupic/swarming/exp_generator/ExpGenerator.py",

    raise RuntimeError("Unsupported field type '%s'" % (fieldType))
RuntimeError: Unsupported field type 'bool'

I’m not using the latest nupic ( 0.3.6.dev0).
