DateTime Encoding defaults in swarming

Hi,

I wanted to know what are the default (n,w) used for encoding timeOfDay, dayOfWeek, season etc. for swarming.

Thank you

There’s no default. The point of swarming is to try different values over and over and keep the best ones. Perhaps you are asking about the first values swarming tries? (I don’t know the answer to that question.)

If you’re just looking for some sane defaults, here’s the hot gym encoder defaults:

github.com

numenta/nupic/blob/master/examples/opf/clients/hotgym/simple/model_params.py#L66-L73


'timestamp_timeOfDay': {   'fieldname': u'timestamp',
                           'name': u'timestamp_timeOfDay',
                           'timeOfDay': (21, 1),
                           'type': 'DateEncoder'},
'timestamp_weekend': {   'fieldname': u'timestamp',
                         'name': u'timestamp_weekend',
                         'type': 'DateEncoder',
                         'weekend': 21}

Keep in mind that only “time of day” and “weekend” information is being encoded here.

Another example is the standard params from here:

github.com

numenta/nupic/blob/99d8b7470993d338090c414fe0dd98a24923feea/src/nupic/frameworks/opf/common_models/anomaly_params_random_encoder/best_single_metric_anomaly_params_cpp.json#L28-L32


"type": "DateEncoder",
"timeOfDay": [
  21,
  9.49
],
