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. Reinforcement learning encompasses both a science of adaptive behavior of rational beings in uncertain environments and a computational methodology for finding optimal behaviors for challenging problems in control, optimization and adaptive behavior of intelligent agents. Reinforcement learning is a natural solution for strategic optimization, and it can be viewed as an extension of traditional predictive analytics that is usually focused on myopic optimization. Reinforcement learning consists of learning to decide in a given situation what action is the best to achieve an objective. The experiment shows that Neural Combinatorial Optimization achieves close to optimal results on 2D Euclidean graphs with up to 100 nodes. In particular, different environmental conditions may require different search operations to track the moving POF more effectively. In policy search, the desired policy or behavior is found by iteratively trying and optimizing the current policy. These values — such as the discount factor [latex]\gamma [/latex], or the learning rate — can make all the difference in the performance of your agent. They collectively generate high quality solutions in the close neighborhood of POS and provide a faster convergence, which makes the algorithm well suited for responding to varying degrees of the environmental changes. 1166-1185, Information Sciences, Volume 545, 2021, pp. 989 0 obj We explore how the supply chain management problem can be approached from the reinforcement learning (RL) perspective that generally allows for replacing a handcrafted optimization model with a generic learning algorithm paired with a stochastic supply network simulator.

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. In recent years, generative adversarial networks (GANs) have garnered increased interest in many fields due to their strong capacity to learn complex real data distributions. We first construct a basic ACE scheme based on number-theoretic assumptions (i.e., DBDH assumption), and this scheme can control not only what users can read but also what they can write. Their abilities to enhance RS by tackling the above challenges have also been demonstrated in numerous studies. Firstly, we introduce the concepts of DMOPs investigated in this section. endobj However, existing ACE requires a centralized sanitizer, hindering its successful application in IoE.

Information Sciences, Volume 546, 2021, pp. If a dynamic multi-objective evolutionary algorithm (DMOEA) could observe the severity of detected changes, it can effectively adapt to the changing environment in time and guide the population to move towards the POF during whole evolution. No additional time-consumptive pre- or post-processing for the personalisation is needed. Recommender systems (RS) now play a very important role in the online lives of people as they serve as personalized filters for users to find relevant items from a sea of options. Placement Optimization is an important problem in systems and chip design, which consists of mapping the nodes of a graph onto a limited set of resources to optimize for an objective, subject to constraints. Deep Reinforcement Learning for Multi-objective Optimization. Reinforcement Learning (RL) [27] is a type of learning process to maximize cer-tain numerical values by combining exploration and exploitation and using rewards as learning stimuli. First, the K-nearest neighbour (KNN) algorithm is applied to the training data set to form a locality-constrained dictionary by excluding the samples separated from testing samples in the Euclidean space. This course aims at introducing the fundamental concepts of Reinforcement Learning (RL), and develop use cases for applications of RL for option valuation, trading, and asset management. This is Bayesian optimization meets reinforcement learning in its core. Our approach allows us to incorporate all three design parameters and Evolutionary multiobjetive optimization in non-stationary environments,... K. Sindhya, Hybrid evolutionary multi-objective optimization with enhanced convergence and diversity. by Gao Tang, Zihao Yang Stochastic Optimization for Reinforcement Learning Apr 202014/41. The large-scale unknown industrial processes are tackled by the reinforcement learning method and the multiagent game theory plant-wide performance optimization [33]. We present an improved attack method using Discrete Cosine Transform based on boundary attack plus plus mechanism, and apply it on attacking object detectors offline and online. One of the most popular approaches to RL is the set of algorithms following the policy search strategy. Reinforcement learning is an unsupervised optimization method, inspired by behaviorist psychology, to find the best control strategies to achieve the desired objectives and also to maximize the defined benefits and rewards in a dynamic environment. Type III test functions illustrate that POF changes, but POS remains unchanged. Hopefully we will convince you that it is both a powerful conceptual framework to organize how to think about digital optimization, as well as a set of useful computational tools to help us solve online optimization problems. To gain a comprehensive understanding of these research efforts, we review the corresponding studies and models, organizing them from a problem-driven perspective. Therefore, combining feature transfer matrix with mutli-view clustering is an innovation of the CTR data prediction process. According to the dynamism correlations of decision space at different time, our proposed algorithm can learn valuable information from the dynamic environment, based on which to determine the appropriate prediction-based strategy to adapt to the environmental changes. utilized a reinforcement learning-based memetic particle swarm optimization (RLMPSO) approach during whole search process. The change response mechanisms including knee-based prediction, center-based prediction and indicator-based local search are incorporated to improve both local and global tracking ability, facilitate the convergence speed and preserve population.
