In order to quantitatively verify the correspondence between direction and diversity, we visualize the distribution of cosine similarities among multiple references for each context for a set of 1000 random samples drawn from the test dataset.
for a context x k and its associated reference responses [y k,0 , y k,1 , • • • ], we compute the cosine similarity between In Figure 3, we compare the distribution of our model with that of MTask, which does not employ our regularization terms.
