Which of the following is the MOST correct way to run a trained model on test data? Consider the sentence:\ "Data science is fun"\ In a bigram language model, which probability expression correctly represents the probability of the word "is"? We are given the Q, K, V matrices to compute the scaled dot product attention matrix for a transformer.\ Keeping everything else same we double every value in the V matrix.\ How will this change the scaled dot product attention scores that are computed?
