English(EN) Does On-Policy Distillation Need to Complete Every Rollout?

新方法通过截断 rollout 加速 AI 模型训练

研究人员开发了一种名为随机截断 On-Policy Distillation (STOPD) 的方法,通过随机截断 student rollout 来加速 on-policy distillation (OPD)。该技术通过不要求每次训练步骤都完成 rollout 来降低计算成本。STOPD 使用分块逆概率加权来补偿采样偏差,这可以保留预期的梯度和,并为 SGD 和 Adam 等常用优化器提供更新误差界限。评估表明,STOPD 可将生成的 token 减少 25-48%,同时保持与标准 OPD 相当的准确性,从而实现 1.3-2.2 倍的训练加速。 AI

影响 该方法可以显著降低训练 AI 模型所需的计算成本和时间,从而可能加速研究和开发。

    On-Policy Distillation 是否需要完成每次 rollout?

    arXiv:2610.21337v1 Announce Type: cross Abstract: On-policy distillation (OPD) effectively transfers capabilities from a teacher to a student through feedback on student-generated rollouts. However, generating complete student rollouts and computing teacher feedback for every tok…
