Hindsight Foresight Relabeling for Meta-Reinforcement Learning

Webboptimal goal-conditioned policy and therefore does not need to perform any hindsight goal relabeling. GoFAR’s relabeling-free training is of significant practical benefits. First, it enables more stable and simpler training by avoiding sensitive hyperparameter tuning associated with HER that cannot be easily performed offline [52].

WebbThis work provides a principled approach to hindsight relabeling, compared to heuristics common in literature, which also extends its applicability. It also proposes an RL and an Imitation Learning algorithm based on Inverse RL relabeling. Prior relabeling methods can be seen as a special case of the more general algorithms derived here.

Webb1 feb. 2024 · Compared to standard relabeling techniques, Generalized Hindsight provides a substantially more efficient reuse of samples, which is empirically demonstrated on a suite of multi-task navigation and manipulation tasks. One of the key reasons for the high sample complexity in reinforcement learning (RL) is the inability to transfer … Webb14 mars 2024 · To solve this alignment problem, they propose a two-phase hindsight relabeling algorithm that utilizes successful and failed instruction-output pairs. Hindsight means understanding or realization of something after it has happened; it is the ability to look back at past events and perceive them in a different way.
