在前面的部分中,我们确定了Decision Transformer可以产生有效的策略(actor)。我们现在评估Transformer模型是否也可以成为有效的critic。我们将Decision Transformer修改为在Key-to-Door环境中输出除了动作token之外的回报token。此外,没有给出第一个回报token,而是对其进行预测(即模型学习初始分布 ),类似于标准的自回归生成模型。
本文的目的是通过autoregressive model的方式来生成动作,进而取代掉传统 RL 的MDP方式来得到最优策略。本文提出了Decision Transformer,其输入为 desired return, past states 以及 past actions,输出为当前时间步的 action。这样做的好处是跳过了传统TD Learning中导致训练不稳定的因素。 本文考察offline learning这个设定,...

The Decision Transformer was proposed by “Decision Transformer: Reinforcement Learning via Sequence Modeling” by Chen L. et al. It casts (offline) Reinforcement Learning as aconditional-sequence modelingproblem. Specifically, DT model is a causal transformer model conditioned on the desired return, ...
