Confidence Score

[malahmadi1]

Can I obtain a confidence score for each guess?

Thanks,

Hello @malahmadi1

Yes.

Now you have guess.probabilities(source_code) that gives you the probability for each language.
The first probability can be used as a confidence.

Example:

from pprint import pprint
from guesslang import Guess


guess = Guess()

source_code = """
    % Quick sort

    -module (recursion).
    -export ([qsort/1]).

    qsort([]) -> [];
    qsort([Pivot|T]) ->
          qsort([X || X <- T, X < Pivot])
          ++ [Pivot] ++
          qsort([X || X <- T, X >= Pivot]).
"""

probabilities = guess.probabilities(source_code)

pprint(probabilities)
