Abstract
A proactive interaction system includes memory which stores a contextual model. The contextual model includes supporting memory storing a representation of each of a set of past observations. Each of the past observations having an observed reward for a respective user for a respective action selected from a set of candidate actions. The contextual model is configured for estimating a reward for each of a current set of candidate actions, based on the stored representations of past observations and a representation of a current user. Each candidate action is associated with a respective action representation. A contextual bandit selects one of the candidate actions, based on the estimated reward for each of the set of candidate actions, to optimize a cumulative reward over a sequence of candidate action selections. An act output component performs a user-detectable act based on the selected one of the candidate actions.
