Ensemble methodology has proved to be one of the strongest machine learning techniques. In spite of its huge success, most ensemble methods tend to generate unnecessary large number of classifiers, which entails an increase in memory storage, computational cost, and even a reduction of the generalization performance of the ensemble. Ensemble selection addresses these shortcomings by searching for...
In this paper, we propose a transmission expansion planning (TEP) framework combined with a cost allocation method based on cooperative game theory. It is a two-step model in which the first step includes the procedure of transmission expansion plan and the latter is comprised of cost allocation process. TEP is derived based on two criteria: reliability and the economic benefits and we use the cost...
An auction-based algorithm is proposed for subcarrier assignment for multiple users amplify and forward (AT) orthogonal frequency division multiple access (OFDMA) system aiming to maximize the fairness index. The proposed algorithm is based on one-shot auction, where each user submits bids for all subcarriers at once based on the Shapley value, a well-known cooperative-game theoretic concept. The...
In this paper, we consider cooperative game with stochastic payoffs and give the definition of the Shapley value for it, which is obtained by extending the classical case. Then we provide explicit expression for the Shapley value of the cooperative game with stochastic payoffs, and discuss its existence and uniqueness. Finally, the properties of the Shapley value of convex cooperative game with stochastic...
We propose a new approach to clustering. Our idea is to map cluster formation to coalition formation in cooperative games, and to use the Shapley value of the patterns to identify clusters and cluster representatives. We show that the underlying game is convex and this leads to an efficient biobjective clustering algorithm that we call BiGC. The algorithm yields high-quality clustering with respect...
In this paper a two level resource allocation scheme is proposed to enhance the Quality of Service (QoS) for multimedia services in LTE downlink system. It corresponds to a solution that combines cooperative game theory, a virtual token mechanism, and the EXP-RULE algorithm. By using cooperative game theory such as bankruptcy game and Shapley value, the proposed mechanism works by forming coalitions...
The LTE specification provides QoS of multimedia services with fast connectivity, high mobility and security. However, 3GPP specifications have not defined scheduling algorithms to support real time and non-real time application services. In this paper we propose a two level scheduling scheme composed by cooperative game concept and EXP-RULE scheduling algorithm. By using cooperative game theory such...
In Supply Chain Environment, the boundary of cost management is not limited in one enterprise, but extend to inter-organizational cooperation, which bring on the inter-organizational cost management. Traditional single-factor cost allocation method and activity-based costing could not satisfied the need of inter-organizational cost allocation, while cooperative game theory is always applied to solve...
According to the characteristics of cooperation and production of the value of information sharing among enterprises in a general three-level supply chain, the index of participation motivation and correction coefficient are added in this paper to improve traditional Shapley value as the profit allocation strategy among supply chain enterprises. The range of values of the index of the participation...
In the deregulated power systems, the interruptible load management (ILM) is widely used as an effective measure to ensure reliability and mitigate the market price spike. A critical issue is the incentive paid to the consumers to participate in the ILM. This paper addresses the quantification and allocation of ILM's benefit from mitigating the wholesale price spike. This benefit is calculated within...
This paper proposes a novel loss reduction allocation method in distribution systems in the presence of distributed generation (DG) units. The proposed method aims to procure the participation of each DG unit in the reduced amount of energy losses in distribution systems brought about by participation of all DG units in power market. The method is based on the assumption that DG units have private...
Allocating losses due to transmission in deregulated power market has become an important issue due to the changed operating mode of restructured power system. The difficulty with the job of loss allocation to the participating players lies in the fact that transmission losses have mutual couplings thus having no acceptable engineering solutions. Game theoretic approach might be an acceptable approach...
This paper addresses the problem of spectrum sharing in cognitive radios where secondary users cooperatively sense the spectrum for identifying and accessing unoccupied spectrum bands. It is shown that this scenario can be modeled as a cooperative game to allocate spectrum resources fairly to each user. Users form coalitions to jointly sense and share the spectrum. The worth of each user is calculated...
With globalization of the world economy, supply chain management has been emphasized as one of the most important management strategies. And, supply chain profit allocation is a significant part in supply chain management, which keeps the supply chain running efficiently and steadily. This paper, comprehensively discusses the supply chain profit allocation issue, based on cooperation game theory....
Although video-on-demand (VoD) services are provided by many ISPs, the amount of content provided by each VoD service is one order smaller than that provided by rental video services, so the limited content count is one of the obstacles to widespread VoD services. To solve this problem, ISPs can form a coalition with other ISPs and use content owned by other ISPs. However, to form a coalition among...
The use of graph theory in social network analysis to identify the most important actors is well-known. More recently game theory has also been applied to measure centrality as variation in the power due to the social structure. Here we present such a solution concept from cooperative game theory, the Shapley value, to identify key players engaged in a network. The communication structure among the...
[Summary form only given]. In a restructured power market, the network cost is to be allocated between multiple players utilizing the system in varying capacities. Cooperative game approaches based on Shapley Value and Nucleolus provide stable models for embedded cost allocation of power networks. Varying network usage necessitates the introduction of probabilistic approaches to cooperative games...
In this paper, the cost allocation methods for power grid investment are discussed in two conditions according to the benefit of each participant after the gird expansion. In the case that each player gets a net profit, Core and Nucleolus value concepts in Cooperative game theory are applied to allocate the expansion cost among them. In the other case that some players appose the power grid expansion...
This paper generalizes the Shapley Value to a non-symmetric value for transferable utility games with two level coalition structure. Non-symmetry exists in players and in both two-level coalition structures. We present seven axioms to characterize this value and provide a property which show that our result consistent with Levy and McLean's weighted coalition structure value and E. Kalai and D. Sament's...
Integrated Supply (I/S) has developed dramatically since its emergence in 1990s. But the buyers do not contact with the suppliers directly under general integrated supply model, which will lead to losing the direct control over them. I/S model by third-party logistics(TPL) may overcomes the disadvantage of traditional I/S model. A key problem of TPL integrated supply is to allocate the supply cost...
