model based就是有一个world model可以用来做planning，而model free就是没有对env dynamics进行建模，传...
判断model-based和model-free最基本的原则是：有没有可依据的model，也就是经过policy得到action之前，它...
Computational analyses of instrumental learning (involved in predicting which actions will be rewarded) have paid substantial attention to the critical distinction betweenmodel-freeandmodel-basedforms of learning and computation (see Fig.1). Model-based strategies generate goal-directed choices employing a...
Model指的是针对环境的建模,即输入Action,环境的响应:Reward和State。 Model-Free:环境对输入的响应就是一个映射,without model,如常见的深度强化学习DQN/A3C/PPO等; Model-Based:环境对输入的响应是统计概率分布P(s_new|s,a)及P(r|s,a),如动态规划等传统强化学习方法。... ...
Although model-free RL caching outperforms the model-based approach in high-variance arrival scenarios, it requires significantly longer training times due to its exploration phase. Model-based learning’s quick adaptability to environmental changes and fast convergence rate make it a desirable ...

In this task, the reward contingency is fixed for each state of the final choice, which enabled us to examine the change in the weight for model-based and model-free learning for an individual. The results showed that proselfs had a larger mean reward gain in the early phase of the ...
文章要点:这篇文章提出了一个Model-Based Model-Free (MBMF)算法,通过学习一个dynamics model然后作为先验来做model free optimization,这里的model free optimization指的是基于Gaussian Process (GP) 的Bayesian Optimization (BO)。 具体的,如果dynamics model是未知的,就先学一个 ...
