Web7 de nov. de 2024 · Simulation shows that the PPO algorithm without a hierarchical structure cannot complete the task, while the hierarchical PPO algorithm has a 100% success rate on a test dataset. WebHierarchical Proximal Policy Optimization Using an appropriate step size in policy space is critical for stable policy learning. We adopt the approach used by Prox-imal Policy Optimization (PPO) (Schulman et al.,2024), which modiﬁes the cost function in a way that prevents large changes to the policy while only requiring the computation inari flowtriever catheter

WebRRHF 可以在不需要人类干预的情况下，以类似于 Fine-tuning 的速度将语言模型的输出概率与人类偏好对齐。RRHF 还与其他方法(如 PPO)相比，具有更简单的代码、更少的模型和更少的 hyper 参数。在测试数据上，RRHF 的性能与 PPO 相似，这证明了该方法的有效性。 WebPPO, however, is sensitive to hyperparameters and requires a minimum of four models in its standard implementation, which makes it hard to train. In contrast, we propose a novel learning paradigm called RRHF, which scores responses generated by different sampling policies and learns to align them with human preferences through ranking loss.
