Now that we have the intuition for the unigram case, let's smooth our Berkeley Restaurant Project bigrams. Figure 3 .6 shows the add-one smoothed counts for the bigrams in Fig. 3.1 . Figure 3 .7 shows the add-one smoothed probabilities for the bigrams in Fig. 3 .2. Recall that normal bigram probabilities are computed by normalizing each row of counts by the unigram count:
