Lab08 Statistical Language Model (SLM) A statistical language model is a probability distribution over sequences of words. Given such a sequence, say of length m, it assigns a probability $P(w_1, \ldots, w_m)$ to the whole sequence. One model solution is to make the assumption that the probability distribution for a word depends only on the […]
