And in this case, it is the mean reduction of num_of_word_piece - 1 word_pieces. In-graph tokenizers, unlike other Hugging Face tokenizers, are actually Keras layers and are designed to be run specified all the computation will be performed with the given dtype. If we have a good N-gram model, we can predict p (w | h) - what is the probability of seeing the word w given a history of previous words h - where the history contains n-1 words. # there might be more predicted token classes than words. When computing sentence probability, do we need to prepend the sentence with a dummy start token (e.g. To make this a more computationally-efficient experiment, I did not train the model on the complete dataset. 1 corresponds to a sentence B token.
