Suppose we train a trigram language model with add-one smoothing on a given corpus. The corpus contains V word types. Express a formula for esti- mating P(w3 w1,w2), where w3 is a word which follows the bigram (w1,w2) in terms of various N-gram counts and V. Use the notation c(w1,w2,w3) to denote the number of times that trigram (w1,w2,w3) occurs in the corpus, and so on for bigrams and unigrams Suppose we train a trigram language model with add-one smoothing on a given corpus.
