对话场景的世界模型本质上建模的会话状态预测 + 用户反馈预测,输入为对话state 和 对话action, 可以类比于目前chatGPT训练过程中使用的reward model。 MPC 模型预测控制(model predictive control)没有构建一个显示的策略函数,而是直接根据环境模型选择下一个动作。它是一种基于模型的迭代方法,核心思想是:每次选择动作的...
简单的MPC+model based 方案 MPC+model based model based + planning 一般model based 在不考虑限制跟环境交互的次数的前提下,model free的性能就是model based的上限。 所以如果需要考虑最终性能超过model free,一般还是得考虑planning。例如MCTS。 AlphaZero和Muzero就是一个例子,下面主要讲下Muzero。 MuZero与Alpha...

基于这N NN个高斯模型,我们就可以去做planning。在每一个time step上,MPC算法通过采样去计算多个最优动作序列,之后采用第一个action,然后重复上述的规划任务。这样的一种算法就称作Planning via Model Predictive Control。 这里采样获取动作的时候,采用的是CEM的方式来获取相对来说比较好的action。然后对每个...
v1.5 版:在 v1.0 版的基础上加入了 MPC 进行闭环控制,在每一步运行后进行重新规划。优点在于对小的模型误差鲁棒性较好,在模型不准确的时候也可以得到很好的控制;缺点在于它的计算代价比较大,需要一边在线运行规划算法,一边收集数据。 v2.0 版:不再使用 MPC 进行反复重新规划,而考虑构建一个策略函数,通过反向传播...

Multi-parametric model-based control (mp-MPC) is a control method that is widely acknowledged for its ability to solve the on-line optimisation problem, involved in traditional MPC, off-line via parametric optimisation. Its main advantage is that it obtains the control actions as explicit function...
