1.2 contribution 划分了两类model-based deep learning 第一类包括DNN,其架构专门用于使用基于模型的方法解决特定问题,这里称为模型辅助网络。 第二类,我们称之为DNNaided推理,由基于模型的算法进行推理的技术组成,该算法的操作由深度学习工具增强。这种与模型无关的深度学习工具的集成允许人们使用基于模型的推理算法,同时...
model-based deep learning 概述及解释说明 1. 引言 1.1 概述 深度学习作为一种机器学习方法,已经在各个领域取得了显著的成就。传统的深度学习方法主要依赖于大量标注的数据进行训练,从而提取出有效的特征表示。然而,这些方法在面对缺乏标签或样本稀缺的问题时表现不佳。因此,基于模型的深度学习方法应运而生。 1.2 ...
尽管这种model-based方法比model-free方法样本效率更高、更灵活,但由于模型偏差,它们的渐近性能通常比model-free差。为了解决这个问题,使用model-based训练的模型作为model-free模型的初始化,然后使用model-free算法将其中参数进行微调 Contribution ① 提出了一种高效的model-based强化学习算法,完成了强化学习baseline中的运...
文章要点:这篇文章主要是deep的model based RL的综述,说起来主要的目标就是一句话achieve high predictive power while maintaining low sample complexity. 主要分了三大类using explicit planning on given transitions,using explicit planning on learned transitions, end-to-end learning of both planning and transiti...
Continuous Deep Q-Learning with Model-based Acceleration 本文提出了连续动作空间的深度强化学习算法。 开始正文之前,首先要弄清楚两个概念:Model-free 和 Model-based。引用 周志华老师的《机器学习》中的一段话来解释这个概念,即: Model-based learning:机器已对环境进行了建模,能够在机器内部模拟出与环境相同或者...
1、Stochastic Lower Bound Optimization (SLBO),出自《Algorithmic framework for model-based deep reinforcement learning with theoretical guarantees》;2、BMPO,出自论文《Bidirectional model-based policy optimization》;3、M2AC,出自论文《Masked model-based actor-critic》;在有关的论文中,除了介绍这些算法...
相较于需要建模的Model-based方法,Model-free方法实现起来较为简单直接,特别是方法如Q-learning和SARSA...
近日,著名机器学习教材《Pattern Recognition and Machine Learning》的作者Christopher Bishop教授更新了他的机器学习新书:Model-Based Machine Learning。 Christopher Bishop 微软研究院在英国剑桥的实验室主任,爱丁堡大学教授 在这本书中介绍了一种新颖的基于模型的机器学习方式——model based machine learning,将具体问题...
Deep learning has been widely recognized as the representative advances of machine learning or artificial intelligence in general nowadays[1,2].This can be attributed to the recent breakthroughs made by deep learning on a series of challenging applications.A deep-learning approach improves the accuracy...
Streamflow and flood forecasting remains one of the long-standing challenges in hydrology. Traditional physically based models are hampered by sparse parameters and complex calibration procedures particularly in ungauged catchments. More than 95 percent of small and medium-sized water catchments in the ...
