We run a hyperparameter grid-search over 4-fold CV with C: (0.1, 1, 10), and gamma: (0.001, 0.01, 0.1, 1).
duration model The temporal duration representation g dur k for the event referred to by the k th predicate is defined similarly to the event representation, but instead of stacking the predicate's span, we stack the hidden representations of the entire sentence H. where A SENT dUR 2 R d⇥size(g pred k ) and b SENT dUR 2 R d .
