, 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)

Of course, there are many other problems, such as how to deal with differences in different languages, how to extract text features, lack of resources, low coverage, difficulties in knowledge representation. basic methods Years, nearly 30 years of time hastily passed, when I wa
