RNN. Bi-directional RNN. DeepRNN. GRU. models compute the probability of occurrence of a numberof words in a particular sequence. The probability of a sequence ofmwords{w1, ...,wm}is denoted asP(w1, ...,wm). Since the numberof words coming before a word,wi, varies depending on its locationin the input document,P(w1, ...,wm)is usually conditioned on awindow ofnprevious words rather than all previous words:P(w1.)

For instance, if the model takes bi-grams, the frequency of each bi-gram, calculated via combining a word with its previous word, would be divided by the frequency of the corresponding uni-gram.
