LAPO: Latent-VariableAdvantage-WeightedPolicy OptimizationforOfflineReinforcementLearning

Neural Information Processing Systems

But in practice, it requires querying the behavior policy which is unknown, and using an erroneous approximation of the behavior policy can negatively affect the performance ([39]).






ExplainMySurprise: LearningEfficientLong-Term MemorybyPredictingUncertainOutcomes

Neural Information Processing Systems

In many sequential tasks, a model needs to remember relevant events from the distant past to make correct predictions. Unfortunately, a straightforward application ofgradient based training requires intermediate computations tobestored for every element of a sequence. This requires to store prohibitively large intermediate data ifasequence consists ofthousands oreven millions elements, and asaresult, makeslearning ofverylong-term dependencies infeasible.
