Perplexity sentence
WebTo calculate the perplexity, first calculate the length of the sentence in words (be sure to include the end-of-sentence word) and store that in a variable sent_len, and then you can calculate perplexity = 1/ (pow (sentprob, 1.0/sent_len)), which reproduces the definition of perplexity we discussed in class.
