Method Details [hide private]

__init__(self, config, contextMonitor, predictorName=None)
(Constructor)

source code 

LastOccurPredictor creator.

Parameters:
  • config (drvr.Configuration) - The config is used to retrieve the predictor settings from the config file.
  • contextMonitor (cntxt.ContextMonitor) - The contextMonitor is needed because it allow the predictor to get the input buffers tokens.
  • predictorName (str) - The custom name of the configuration using this predictor.
Overrides: object.__init__

predict(self, maxPartialPredictionSize, stopList=[])

source code 

Compute the predictions using a simple exponential decay method.

Parameters:
  • maxPartialPredictionSize (int) - Maximum number of suggestion to compute. If this number is reached, the suggestions list is immediatly return. DatabaseConnector.ngram_table_tp() returns the records in descending order according to their number of occurences so the most probable suggestions will be added to the list first. This result in no suggestion quality loss, regardless of the desired number of suggestions.
  • stopList (list) - The stoplist is a list of undesirable words. Any suggestion which is in the stopList won't be added to the suggestions list.
Returns: prdct.Prediction
A list of every suggestions possible (limited to maxPartialPredictionSize).
Overrides: Predictor.predict

learn(self, text)

source code 

This predictor has no ability to learn.

Overrides: Predictor.learn
