.. py:class:: Baseline(frequencies_file)

   Typos correction model, based on SymSpell lookout algorithm

   https://github.com/wolfgarbe/SymSpell

   and simple Random Forest classifier, based on token frequencies
   and edit distance between typo and candidate.

   Requires file containing tokens frequencies in a format "token, frequency".

   Training data: dataframe indexed by "id" and containing columns "identifier", "typo".
   Testing data: dataframe indexed by "id" and containing column "typo".
