Web31 de jul. de 2024 · In 3D off-road terrain, the driving of the unmanned vehicle (UV) is influenced by the combined effect of terrain and obstacles, leading to greater challenges … 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.
