摘要:

我们介绍了一种方法,使经常性的动态模型是时间抽象的。我们的方法,我们称之为自适应跳过间隔(ASI),是基于观察,在许多连续的预测任务,事件发生的确切时间是无关的基本目标。此外,在许多情况下,存在导致特别容易预测的转变的预测区间。我们表明,有预测任务,我们获得的计算效率和预测精度,允许模型进行预测,在采样率,它可以选择自己。

英文摘要:

We introduce a method which enables a recurrent dynamics model to be temporally abstract. Our approach, which we call Adaptive Skip Intervals (ASI), is based on the observation that in many sequential prediction tasks, the exact time at which events occur is irrelevant to the underlying objective. Moreover, in many situations, there exist prediction intervals which result in particularly easy-to-predict transitions. We show that there are prediction tasks for which we gain both computational efficiency and prediction accuracy by allowing the model to make predictions at a sampling rate which it can choose itself.
