Table 1 presents the VI between the learned persona clusters and gold clusters, for varying numbers of personas (P = {25, 50, 100}) and topics (K = {25, 50, 100}).
the probability that character e embodies persona k is proportional to the number of other characters in the plot summary who also embody that persona (plus the Dirichlet hyperparameter α k ) times the contribution of each observed word w j for that character, given its current topic assignment z j .
