, K2, K3.Measurement of Ishimarkov language model: complexity (perplexity)Suppose we have a test data set (a total of M sentences), each sentence Si corresponds to a probability p (SI), so the probability product of the test data set is ∏p (SI). After simplification, we can get Log∏p (si) =σlog[p (si)]. perplexity = 2^-l, where L = 1/mσlog[p (SI)]. (like the definition of entropy)A few intuitive examples:1) Suppose Q (w | u, v) = 1/m,perplexity = M;2)
