Coherence in the Visual Imagination: Local Hill Search Outperforms Thagard's Connectionist Model

چکیده
A cognitive model of the visual imagination will produce “incoherent” results when it adds elements to an imagined scene that come from different contexts (e.g., “computer” and “cheese” with “mouse”). We approach this problem with a model that infers coherence relations from co-occurrence probabilities of labels in images. We show that this algorithm’s serial traversal of networks of co-occurrence relations for a particular query produces greater coherence than one leading model in the field of computational coherence: Thagard’s connectionist model.

A Proposed Improved Hybrid Hill Climbing Algorithm with the Capability of Local Search for Solving the Nonlinear Economic Load Dispatch Problem
This paper introduces a new hybrid hill-climbing algorithm (HHC) for solving the Economic Dispatch (ED) problem. This algorithm solves the ED problems with a systematic search structure with a global search. It improves the results obtained from an evolutionary algorithm with local search and converges to the best possible solution that grabs the accuracy of the problem. The most important goal...
متن کاملNetwork and direct methods of maximising harmony
Paul Thagard (1989t) presents an interesting and important theoretical account of choosing between hypotheses in scientific and everyday domains, describing a network model, ECHO, which aims to embody these ideas. Thagard's integration of philosophical, psychological, and computational considerations is impressive in its breadth, theoretical rigor, and conceptual simplicity. It is a compelling ...
متن کاملDeductive Coherence and Norm Adoption
This paper is a contribution to the formalisation of Thagard's coherence theory. The term 'coherence' is defined as the quality or the state of cohering, especially a logical, orderly, and aesthetically consistent relationship of parts. A coherent set is interdependent such that every element in it contributes to the coherence. We take Thagard's proposal of a coherence set as that of maximising...
متن کاملA Comparison of Local Search Methods for the Multi-Criteria Police Districting Problem on Graph
In the current economic climate, law enforcement agencies are facing resource shortages. The e ective and e cient use of scarce resources is therefore of the utmost importance to provide a high standard public safety service. Optimization models speci cally tailored to the necessity of police agencies can help to ameliorate their use. The Multi-Criteria Police Districting Problem (MC-PDP) conce...
متن کاملExplaining the Level of Human Thought in the Parallel Civilizations Based on Formal Structure and Visual Imagination Formed in Mythical Narratives
Myth, like any other form of narrative, has an undeniable role in visual imagination based on the foundations of mythical thought. Ernst Cassirer, by recovering the fundamental principles of mythical thought, brings against them to the foundations of contemporary rational thought and defines the fundamental features of mythical thought as compared to modern rational thought. He also believes t...
