3.soft-q learning 4. value-based method和PG的关系 1.intro 传统的RL受最优性理论的影响,总假设最优策略是确定性的一种策略,起码在完全观测状态下是确定性的。而之前对于随机策略的看法一般是用于高效探索或者在PG框架下,而这种探索能力的获得一般都是启发性的一些先验知识,eg. intrinsic reward。本文对随机策...
怎么解决Q-learning的局限性呢?解决方法是确保agent既能够优先选择最有希望的动作,又能考虑其他动作。一种思路是让policy的形态和Q函数一致,如图2右边的图所示,也就是 这种概率分布是一种Boltzmann distribution,其中Q函数相当于negative energy。这种概率分布(也称为policy)让每一个action都有一个非零的概率值。从这...

As far as I can tell, Soft Q-Learning (SQL) and SAC appear very similar. Why is SQL not considered an Actor-Critic method, even though it has an action value network (critic?) and policy network (actor?)? I also cannot seem to find a consensus on the exact definition of an Actor...

Standard reinforcement learning algorithms for solving Markov Decision Processes (MDP) tasks are not applicable, as they cannot infer the unobserved states. In this paper, we propose a novel algorithm for POMDPs, named sequential variational soft Q-learning networks (SVQNs), which formalizes the ...
Our method, Inverse soft-Q learning (IQ-Learn) obtains state-of-the-art results in offline and online imitation learning settings, significantly outperforming existing methods both in the number of required environment interactions and scalability in high-dimensional spaces, often by more than 3x. ...
Abstract We present a new statistical relational learning (SRL) framework that supports reasoning with soft quantifiers, such as “most” and “a few.” We define the syntax and the semantics of this language, which we callPSLQ, and present a most probable explanation inference algorithm for it...
