概念定义和应用场景熵正则化和l1 l2 正则化类似,其使用形式都是在现有的loss function的基础上增加额外的一个正则损失项。 一图胜千言: 比较常见的使用方式是在模型的决策层的输出实施熵正则化,约束模型是输出…
4、实验 本文做了格子世界和 Mujoco 上的实验,说明在已有的策略梯度算法上加上这一项 regularization 的提升,特别是对于 sparse reward 任务上的提升。

In this chapter, we motivate the use of entropy regularization as a means to benefit from unlabeled data in the framework of maximum a posteriori estimation. The learning criterion is derived from clearly stated assumptions and can be applied to any smoothly parametrized model of posterior ...
{s}\right)$ towards a few actions or action sequences, since it is easier for the actor and critic to overoptimise to a small portion of the environment. To reduce this problem, entropy regularization adds an entropy term to the loss to promote action diversity:$$H(X) = -\sum\pi\...
伪标签方法在半监督学习中，通过利用未标记数据与标记数据共同训练，提高模型泛化性能。其核心思想是将具有最大预测概率的类作为伪标签。这等同于熵最小化（Entropy Minimization）或熵正则化（Entropy Regularization），即通过减少未标记数据的预测不确定性，使决策边界更适应数据分布，从而减少类重叠，提高类...

Our suggested alternative is to add an entropy regularization to the KL divergence constraint, so as to build an improved TRPO with entropy regularization for KL divergence. We term this method as ERC-TRPO, which directly controls and adjusts the exploration of the agent using its constraint. Fu...
伪标签方法是一种同时从未标记数据和标记数据中学习的监督范式。将具有最大预测概率的类作为伪标签。形式化后等价于熵正则化(Entropy Regularization)或熵最小化(Entropy Minimization). 根据半监督学习的假设,决策边界应该尽可能通过数据较为稀疏的区域,即低密度区域,从而避免把密集的样本数据点分到决策边界的两侧,也...
