Download or read book Multi Objective Decision Making written by Diederik M. Zhou and published by Springer Nature. This book was released on 2022-05-31 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many real-world decision problems have multiple objectives. For example, when choosing a medical treatment plan, we want to maximize the efficacy of the treatment, but also minimize the side effects. These objectives typically conflict, e.g., we can often increase the efficacy of the treatment, but at the cost of more severe side effects. In this book, we outline how to deal with multiple objectives in decision-theoretic planning and reinforcement learning algorithms. To illustrate this, we employ the popular problem classes of multi-objective Markov decision processes (MOMDPs) and multi-objective coordination graphs (MO-CoGs). First, we discuss different use cases for multi-objective decision making, and why they often necessitate explicitly multi-objective algorithms. We advocate a utility-based approach to multi-objective decision making, i.e., that what constitutes an optimal solution to a multi-objective decision problem should be derived from the available information about user utility. We show how different assumptions about user utility and what types of policies are allowed lead to different solution concepts, which we outline in a taxonomy of multi-objective decision problems. Second, we show how to create new methods for multi-objective decision making using existing single-objective methods as a basis. Focusing on planning, we describe two ways to creating multi-objective algorithms: in the inner loop approach, the inner workings of a single-objective method are adapted to work with multi-objective solution concepts; in the outer loop approach, a wrapper is created around a single-objective method that solves the multi-objective problem as a series of single-objective problems. After discussing the creation of such methods for the planning setting, we discuss how these approaches apply to the learning setting. Next, we discuss three promising application domains for multi-objective decision making algorithms: energy, health, and infrastructure and transportation. Finally, we conclude by outlining important open problems and promising future directions.

Download or read book Commodity and Resource Policies in Agricultural Systems written by Richard E. Just and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural, natural resource, and environmental problems are becom ing increasingly interdependent. For example, soil erosion is largely determined by agricultural land use. Both water use and water con tamination depend on land use and technology choice in agriculture. In many areas, the fertilizers and pesticides used in agriculture are ma jor pollutants of ground and surface water, having adverse effects on drinking water and fisheries. Agricultural pollutants such as pesticides also produce adverse health effects for agricultural workers and the consuming public. On the other hand, the availability of water resources and the value of competing land uses influence agricultural production. Additionally, regional air quality problems may affect crops and global environmental trends may have long-term implica tions for farming. Agriculture, natural resources and environmental quality are all heavily regulated in the U. S. , but they are done so by a vast array of competing or unrelated agencies within the U. S. Departments of Agriculture, Interior, and Commerce, the Environmental Protection Agency; and numerous state agencies. Considering the large number of bureaucratically remote public agencies involved and the pervasive in terdependencies between agriculture, natural resources and the environ ment, policies develop which are at best uncoordinated and at worst conflicting and counterproductive. These policies have become sources of controversy as different interest groups struggle to affect their im plementation, as different agencies have fought for administrative con trol and as legislative bodies have attempted to enact piecemeal changes.

This book was released on 2012-12-06 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eugene A. Feinberg Adam Shwartz This volume deals with the theory of Markov Decision Processes (MDPs) and their applications. Each chapter was written by a leading expert in the re spective area. The papers cover major research areas and methodologies, and discuss open questions and future research directions. The papers can be read independently, with the basic notation and concepts ofSection 1.2. Most chap ters should be accessible by graduate or advanced undergraduate students in fields of operations research, electrical engineering, and computer science. 1.1 AN OVERVIEW OF MARKOV DECISION PROCESSES The theory of Markov Decision Processes-also known under several other names including sequential stochastic optimization, discrete-time stochastic control, and stochastic dynamic programming-studiessequential optimization ofdiscrete time stochastic systems. The basic object is a discrete-time stochas tic system whose transition mechanism can be controlled over time. Each control policy defines the stochastic process and values of objective functions associated with this process. The goal is to select a "good" control policy. In real life, decisions that humans and computers make on all levels usually have two types ofimpacts: (i) they cost orsavetime, money, or other resources, or they bring revenues, as well as (ii) they have an impact on the future, by influencing the dynamics. In many situations, decisions with the largest immediate profit may not be good in view offuture events. MDPs model this paradigm and provide results on the structure and existence of good policies and on methods for their calculation.

Download or read book Mixture Weighted Policy Cover written by Dylan Miller and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploration plays a major role in the performance of reinforcement learning algorithms. Successful exploration should force the agent to access parts of the state-action space that it has not been heavily exposed to. This allows agents to find potentially better trajectories in terms of the value function that they yield. Exploration becomes much more difficult however when the environment is nonstationary. This is the case in multiagent reinforcement learning where other agents also learn and so change the dynamics of the environment from the perspective of any single agent. The upper confidence bound style reward bonus that is common in many reinforcement learning algorithms does not take this nonstationarity into account and therefore cannot be successfully applied to the multiagent setting. In this thesis, we propose Mixture-Weighted Policy Cover, a policy iteration algorithm using an upper confidence bound based intrinsic exploration bonus that encourages exploration in episodic multiagent settings by defining a policy cover that favors newer policies.

Download or read book The WTO Case Law of 2001 written by Henrik Horn and published by Cambridge University Press. This book was released on 2004-01-22 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was the first in a groundbreaking series of annual volumes utilized in the development of an American Law Institute (ALI) project on World Trade Organization Law. The project undertakes yearly analysis of the case law from the adjudicating bodies of the WTO. The Reporters' Studies for 2001 cover a wide range of WTO law ranging from classic trade in goods issues to intellectual property protection. Each of the cases is jointly evaluated by an economist and a lawyer, both well-known experts in the field of trade law or international economics. The Reporters critically review the jurisprudence of WTO adjudicating bodies and attempt to evaluate whether the ruling 'makes sense' from an economic as well as a legal point of view, and, if not, whether the problem lies in the interpretation of the law or the law itself. The Studies do not always cover all issues discussed in a case, but they seek to discuss both the procedural and the substantive issues that form the 'core' of the dispute.
