A novel hierarchical graph model is developed to analyze conflicts interrelated on three levels. As an extension of the two-level hierarchical graph model, this new structure contains several smaller graph models, called local graphs, nested at three levels. Decision makers (DMs), states, moves, and preference relations in the three-level hierarchical graph model (3LHGM) are defined. The interrelationships between stabilities in local graph models and the overall graph model are investigated and utilized in developing algorithms to calculate stabilities in the hierarchical graph model. This novel methodology is then illustrated using a generic model of hierarchical climate change governance disputes. Stability calculations can uncover profitable courses of action. The 3LHGM aims to provide insightful resolutions for DMs with a broader vision of the hierarchical conflict they are participating in.

Detection of early changes in dynamical bearing degradation process is essential for analyzing of bearing running status, residual useful life and potential fault(s). To achieve this end, this paper presents an hierarchical graph model based method. hierarchical decomposition is firstly adopted to the collected vibration signal and graphs are then constructed for each decomposed component. Similarity scores are then calculated based on the adaptive input weight fusion taking into account the changing information in different components. A common hypothesis testing is finally employed to make the change decision. Experiment, conducted on the public XJTU-SY data set, demonstrated the effectiveness of the proposed method.

A novel hierarchical graph model, called hierarchical graph model with sequential moves (SHGM), is developed to investigate interrelated conflicts in which common decision-makers (CDMs), participating in all interrelated conflicts, unilaterally move in one subconflict at a time. The preferences of decision-makers are described by a scoring system. Equilibria under different solution concepts are calculated as the indication of possible outcomes or strategic resolutions for decision-makers. This novel methodology is applied to subsidy disputes between the national government in China and two provincial governments, typical hierarchical conflicts containing sequential moves of the national government who wishes to strategically allocate the limited subsidies to encourage the compliance of carbon mitigation policies by the provinces. In-depth analysis is carried out to determine the equilibria that can be evolved from the starting state, called the status quo. Among these equilibria, the most preferred one for the national government, called the optimal equilibrium, suggests meaningful resolutions for each decision-maker. In particular, the national government in China is advised to subsidize the more industrialized province so that both provinces would comply with its carbon mitigation policies.

The coalition in interrelated conflicts with hierarchical structures is analyzed within the framework of basic hierarchical graph model as an extension of graph model for conflict resolution. A basic hierarchical graph model consists of two local graph models with three decision makers: one common decision maker supervising both local graph models, and two local decision makers, each of whom takes part in one local graph model. Two types of coalition, between the common and one local decision maker, and between two local decision makers are discussed. Theorems are proposed, indicating that transition from one equilibrium to another, called equilibrium jump, can only take place in the coalition consisting of common and local decision maker. The change to a more preferred equilibrium for local decision makers could only take place when they temporarily sacrifice their interests. An illustrative example of hierarchical disputes over achieving emission goals between the national and two provincial governments in China are investigated. The results suggest that agreements between the national and one provincial government can be reached. The province will achieve stricter emission goals when being subsidized by the national government. Agreements between the two provinces cannot be formed without the participation of the national government. This study can provide courses of action for decision makers under coalition in dealing with hierarchical conflicts.

A duo hierarchical graph model for conflict resolution is developed to investigate market competition between Airbus and Boeing over aircraft sales in the Asia Pacific region. The duo hierarchical graph model, a significant extension of the graph model for conflict resolution methodology, contains two common decision makers, who take part in two related subconflicts, as well as local decision makers, who participate in only one subconflict. New stability definitions are proposed to describe forms of sanction unique to the hierarchical model. The interrelationships between stabilities in the overall graph model and in the two local models are investigated. Then the duo hierarchical graph model is applied to the competition between Airbus and Boeing in both the wide and narrow body markets in the Asia-Pacific region. The two types of Asian airlines have different operating strategies, so that the two markets constitute sub-competitions that can be modelled naturally using the duo hierarchical graph model. The stability results indicate a resolution for all decision makers that implies marketing strategies for the aircraft manufacturers and guidelines for aircraft purchase by the airlines. Thus, this model provides decision makers with a comprehensive understanding of the dynamics of the comoetition and guidance in identifving beneficial actions.

The general hierarchical graph model, a significant expansion of the graph model for conflict resolution methodology, is designed to analyze interrelated conflicts with hierarchical structures. In a general hierarchical graph model, there are common decision makers, who take part in all related subconflicts, and local decision makers, who participate in only one subconflict. In this paper, preference structures for decision makers in a hierarchical graph model are established, and theorems are developed that elucidate the relationship between stabilities in the overall (hierarchical) model and stabilities in the component submodels. To illustrate, the hierarchical graph model is applied to greenhouse gas emission disputes between USA and China, where local decision makers in the USA are the two parties in Congress, and local decision makers in China are state-owned energy companies. The stability results suggest potential strategic resolutions of bilateral disputes, and how parties can attain them. (C) 2016 Elsevier B.V. All rights reserved.

A basic hierarchical graph model for conflict resolution is proposed to handle a hierarchical conflict with two smaller conflicts as components. The hierarchical model can be represented in matrices and its stabilities calculated. This novel methodology is applied to water diversion conflicts in China, where the two subconflicts are caused by the construction of two local subprojects. Strategic analysis can provide decision makers (DMs) with a comprehensive understanding of a conflict and guidance for action. For basic hierarchical graph model, the matrix approach is an effective and convenient way to represent the model, calculate stability results, and predict equilibria.

To develop strategic insights regarding the aggregatemining disputes in the province of Ontario, Canada, and to better understand their structured power hierarchies, we developed a two-level hierarchical graph model based on three case-specific classical conflict models. The stability analysis of the two-level hierarchical graph model shows that despite producing potential resolutions at the local level (sub-models), the model does not result in an equilibrium. This finding suggests that in the absence of preferences by the common decision-makers (i.e., provincial, and local governments), finding potential resolutions to this class of disputes may be difficult.

PARN: Pyramidal Affine Regression Networks for Dense Semantic Correspondence 1

This paper presents a deep architecture for dense semantic correspondence, called pyramidal affine regression networks (PARN), that estimates locally-varying affine transformation fields across images. To deal with intra-class appearance and shape variations that commonly exist among different instances within the same object category, we leverage a pyramidal model where affine transformation fields are progressively estimated in a coarse-to-fine manner so that the smoothness constraint is naturally imposed within deep networks. PARN estimates residual affine transformations at each level and composes them to estimate final affine transformations. Furthermore, to overcome the limitations of insufficient training data for semantic correspondence, we propose a novel weakly-supervised training scheme that generates progressive supervisions by leveraging a correspondence consistency across image pairs. Our method is fully learnable in an end-to-end manner and does not require quantizing infinite continuous affine transformation fields. To the best of our knowledge, it is the first work that attempts to estimate dense affine transformation fields in a coarse-to-fine manner within deep networks. Experimental results demonstrate that PARN outperforms the state-of-the-art methods for dense semantic correspondence on various benchmarks.
