Trigram probability example
Web+ λ 3 P e (w n-2,n-1) (trigram probability) where λ 1 , λ 2 and λ 3 are weights. They must add up to 1 (certainty), but assuming that trigrams give a better estimate of probability than bigrams, and bigrams than unigrams, we want λ 1 < λ 2 < λ 3 , e.g. λ 1 = 0.1, λ 2 = 0.3 and λ … WebSep 17, 2024 · For example, to calculate the probabilities of a given NGram model using NoSmoothing: a.calculateNGramProbabilities(NoSmoothing()) LaplaceSmoothing class is a simple smoothing technique for smoothing. ...
