[27] utilized a reinforcement learning-based memetic particle swarm optimization (RLMPSO) approach during whole search process. 2017 [1]. x�cbd�g`b`8 $����;�� Afterwards, three distinct, yet complement, prediction-based mechanisms which relocate the individuals are ensembled based on Q-learning framework according to the location correlations of optimal solutions at different time. We present a generic and flexible Reinforcement Learning (RL) based meta-learning framework for the problem of few-shot learning. • Reinforcement learning has potential to bypass online optimization and enable control of highly nonlinear stochastic systems. To solve this problem, we take the Euclidean distance information between the training samples and testing samples into consideration to construct a new dictionary for sparse representation. These prediction-based models, either utilizing machine learning technologies (e.g., autoregressive models [44], the transfer learning model [14], and the Kalman Filter-based model [23]) or capturing the historic movement of the POS center [24] to relocate the individuals in the population, are considered state-of-the-art solutions. Reinforcement learning is an area of Machine Learning. Firstly, the general framework of RL-DMOEA is outlined. Placement Optimization with Deep Reinforcement Learning. of the CMDP setting, [31, 35] studied safe reinforcement learning with demonstration data, [61] studied the safe exploration problem with different safety constraints, and [4] studied multi-task safe reinforcement learning.

Nonzero-Sum Game Reinforcement Learning for Performance Optimization in Large-Scale Industrial Processes Abstract: This article presents a novel technique to achieve plant-wide performance optimization for large-scale unknown industrial processes by integrating the reinforcement learning method with the multiagent game theory. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper. However, most current approaches lack learning or feedback mechanisms which can be assessed through environment information to guide the search directions. One of the most popular approaches to RL is the set of algorithms following the policy search strategy. Experiments Advantages Flexible dual function space, rather than constrained in GTD2 Directly optimized MSBE, rather than surrogates as in GTD2 and RG Directly … It should be noted that it is effective to track the movement of POF via evolution direction of the global knee solution, because higher severity of change demands greater exploration capability. However, when samples from different classes are highly correlated with each other, it makes the classification task challenging. The advantages offered by these models are unparalleled, however, similar to any other computing discipline, they are also vulnerable to security threats. 993 0 obj The noisy data from such a cheap device are well handled. For this purpose, we consider the Markov Decision Process (MDP) formulation of the problem, in which the optimal solution can be viewed as a sequence of decisions. To solve DMOPs, the proposed RL-DMOEA is tested on twelve IEEE CEC 2015 [13] test problems, including four FDA instances, one DIMP instance, three HE instances and four DMOP instances.
