KL penalty和Clip PPO算法的核心在于更新策略梯度,主流方法有两种,分别是KL散度做penalty,另一种是Clip剪裁,它们的主要作用都是限制策略梯度更新的幅度,从而推导出不同的神经网络参数更新方式 采用KL penalty算法,那么神经网络参数按照下面的方式更新 采用Clip算法,那么神经网络参数按照下面的方式更新 那么采用KL penalty算...
PPO（Proximal Policy Optimization）是基于策略的强化学习算法，属于off-policy算法。核心在于通过KL散度或Clip方法限制策略梯度更新的幅度，从而优化策略。使用KL penalty算法时，神经网络参数按特定公式更新；采用Clip算法时，参数更新方式亦有差异。这两种方法在PPO算法中体现为更新策略的不同方式。伪代码展示...
_Technical detail note: The above diagram makes it look like both models generate different responses for the same prompt, but what really happens is that the RL policy generates text, and that text is fed into the initial model to produce its relative probabilities for the KL penalty._ Optio...
Malaysia faces up to RM500m penalty for dropping KL-Spore HSR project, says Dr Mahathir KUALA LUMPUR (May 28): The decision to drop plans to build the high-speed rail link between Kuala Lumpur and Singapore is final, Prime Minister Tun Dr Mahathir Mohamad said, adding that...
There were seven attributes being studied, namely the informations, the situation at the station, the situation in the KL Monorail, customer service, safety, efficiency and other aspects. The analysis found that the overall customer satisfactionis mean is 4.86. Based on the measurement of Penalty-...

The KL divergence term penalizes the RL policy from moving substantially away from the initial pretrained model with each training batch, which can be useful to make sure the model outputs reasonably coherent text snippets. Without this penalty the optimization can start to generate text that is ...
