TemporalPositive-unlabeledLearningforBiomedical HypothesisGenerationviaRiskEstimation

Neural Information Processing Systems

Then, the key is to capture the temporal evolution of node pair (term pair) relations from just the positive and unlabeled data. We propose a variational inference model to estimate the positive prior, and incorporate it in the learning of node pairembeddings, which arethenused forlinkprediction.





Variational Policy Gradient Method for Reinforcement Learning with General Utilities

Neural Information Processing Systems

In recent years, reinforcement learning (RL) systems with general goals beyond a cumulative sum of rewards have gained traction, such as in constrained problems, exploration, and acting upon prior experiences. In this paper, we consider policy optimization in Markov Decision Problems, where the objective is a general concave utility function of the state-action occupancy measure, which subsumes several of the aforementioned examples as special cases.
