Methods¶
__init__ ([prob_dict, log, normalize]) |
Construct a new probability distribution from the given dictionary, which maps values to probabilities (or to log probabilities, if log is true). |
discount () |
Return the ratio by which counts are discounted on average: c*/c |
generate () |
Return a randomly selected sample from this probability distribution. |
