+Pointer Sentinel Mixture Models

+
+The ETHICS dataset is a benchmark that spans concepts in justice, well-being,
+duties, virtues, and commonsense morality. Models predict widespread moral
+judgments about diverse text scenarios. This requires connecting physical and
+social world knowledge to value judgements, a capability that may enable us
+to steer chatbot outputs or eventually regularize open-ended reinforcement
+learning agents.
