relative_deltah_fl(corpus_context, segment, stop_check=None, call_back=None)¶
Calculate the average functional load of the contrasts between a segment and all other segments, as the decrease in corpus entropy caused by a merger.
corpus_context : CorpusContext
Context manager for a corpus
segment : str
The target segment.
stop_check : callable, optional
Optional function to check whether to gracefully terminate early
call_back : callable, optional
Optional function to supply progress information during the function
The difference between a) the entropy of the choice among non-homophonous words in the corpus before a merger of s1 and s2 and b) the entropy of that choice after the merger.
