The Naive Bayes model assumes that all features are conditionally independent given the class label. For our purposes, this means that the probability of seeing a particular word in a document with class label $y$ is independent of the rest of the words in that document. Implement the `p_word_given_label` function in the [Naive Bayes Block](#Naive-Bayes-Block). This function calculates P (w|y) (i.e., the probability of seeing word w in a document given the label of that document is y). Use your `p_word_given_label` function to compute the probability of seeing the word amazing given each sentiment label. Repeat the computation for the word dull. print ("P('amazing'|pos):", nb.p_word_given_label("amazing", POS_LABEL)) print ("P('amazing'|neg):", nb.p_word_given_label("amazing", NEG_LABEL)) print ("P('dull'|pos):", nb.p_word_given_label("dull", POS_LABEL)) print ("P('dull'|neg):", nb.p_word_given_label("dull", NEG_LABEL)) Which word has a higher probability, given the positive class? Which word has a higher probability, given the negative class? Is this behavior expected?
