① 政府停摆或再度发生


政府停摆或许会再度发生。上周末两党在移民处置问题上的谈判破裂,焦点反倒不是特朗普总统的建墙事宜。民主党想要对美国移民及海关执法局的拘留人数设上限,而共和党却不认同。除非在周五晚间临时性支出法案到期前谈判有重大进展,否则政府将再次陷入停摆。那样的话,美国国家税务局将遭受打击,因其正在处理成百上千万人的纳税申报。

Sparse reward is one of the most challenging problems in reinforcement learning (RL). Hindsight Experience Replay (HER) attempts to address this issue by converting a failed experience to a successful one by relabeling the goals. Despite its effectiveness, HER has limited applicability because it lacks a compact and universal goal representation. We present Augmenting experienCe via TeacheR's adviCE (ACTRCE), an efficient reinforcement learning technique that extends the HER framework using natural language as the goal representation. We first analyze the differences among goal representation, and show that ACTRCE can efficiently solve difficult reinforcement learning problems in challenging 3D navigation tasks, whereas HER with non-language goal representation failed to learn. We also show that with language goal representations, the agent can generalize to unseen instructions, and even generalize to instructions with unseen lexicons. We further demonstrate it is crucial to use hindsight advice to solve challenging tasks, and even small amount of advice is sufficient for the agent to achieve good performance.
