  • Topological Relation Metric of Fuzzy Regions Based on Flou Set
    Computer Engineering, 2013
    Co-Authors: Bi Ling-ling
    Abstract:

    A method which describes the fuzzy regions using flou sets is proposed aiming at measuring the topological relations between fuzzy regions.It not only accords with the Cognitive Principle of people,but also is suitable for high-order fuzzy case.Based on the representation model of fuzzy regions,the metric description of topological relations between fuzzy regions is proposed.It is valuable in the fields such as spatial information query and spatial reasoning.

  • Fuzzy overlay analysis model based on Flou sets
    Application Research of Computers, 2013
    Co-Authors: Bi Ling-ling
    Abstract:

    The method described the fuzzy regions using Flou sets.Then it proposed an overlay analysis model of fuzzy raster map layers based on Flou sets.The model could complete general fuzzy overlay and weighted fuzzy overlay.The fuzzy overlay model could avoid the difficulty in dealing with the relations between fuzzy spatial objects through using fuzzy sets to represent the fuzzy region,and the fuzzy overlay result accord with the Cognitive Principle of people.The practical case shows that this model can well solve fuzzy overlay analysis between the map layers described as Flou sets.

  • The search for simplicity : A fundamental Cognitive Principle?
    The Quarterly Journal of Experimental Psychology Section A, 1999
    Co-Authors: Nick Chater
    Abstract:

    It is proposed that the Cognitive system imposes patterns on the world according to a simplicity Principle: Choose the pattern that provides the briefest representation of the available information. The simplicity Principle is normatively justified-patterns that support simple representations provide good explanations and predictions on the basis of which the agent can make decisions and actions. Moreover, the simplicity Principle appears to be consistent with empirical data from many psychological domains, including perception, similarity, learning, memory, and reasoning. Thus, the simplicity Principle promises to serve as the starting point for the rational analysis of a wide range of Cognitive processes, in Anderson's (1990, 1991a) sense. The simplicity Principle also provides a framework for integrating a wide range of existing psychological proposals.

  • analysis on english near synonym discrimination column in advanced learner s dictionary based on oald 6th edition
    Journal of Zhaoqing University, 2008
    Co-Authors: L I Huimin
    Abstract:

    The characteristics of mainstream learner's dictionary OALD(6th Edition) concerning its treat-ment of English near-synonym discrimination columns can be analyzed from four different perspectives,which are respectively the validity of index,the range of cluster,the explicitness of discriminating criteria and the function of examples.Its advantages are that the setting of microstructure and macrostructure are relatively mature,the application of Cognitive Principle and user-friendly Principle are relatively proper,while its disad-vantages are failure to provide a consulting index in front and back materials,incompleteness in clusters,inex-plicitness of discriminating criteria and shallow function of examples.

  • Stable throughput and delay performance in Cognitive cooperative systems
    IET Communications, 2011
    Co-Authors: Xu Bao, Philippe Martins, Tiecheng Song, Lianfeng Shen
    Abstract:

    The Cognitive cooperative system with coexisting scenario of multiple primary users and one secondary capable of relaying is considered in this study. The primary users transmit packets in orthogonal subchannels. According to the Cognitive Principle, the secondary activity cannot interfere with the primary performance. Therefore in this study, the secondary user makes use of the spectrum when sensed idle. Based on the proposed media access control (MAC) protocol, the authors derive the stable throughput and delay slots expressions of each primary user with secondary relaying. They also achieve the stable network constraints of relaying probability e, the feasible range of primary arrival rates and the maximum allowed secondary transmitting power which is to make a tradeoff between the stable throughput of the primary and secondary user. Simulation results show that secondary relaying can increase the primary and secondary throughput and also reduce the delay slots when designing an appropriate e.

  • GLOBECOM - Stable Throughput Analysis of Multi-User Cognitive Cooperative Systems
    2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
    Co-Authors: Xu Bao, Philippe Martins, Tiecheng Song, Lianfeng Shen
    Abstract:

    The Cognitive cooperative system with coexisting scenario of multiple primary users and one secondary capable of relaying is considered. The primary users transmit packets in orthogonal sub-channels. According to the Cognitive Principle, the secondary activity cannot interfere with the primary performance. Therefore, in this paper, the secondary user makes use of the spectrum when sensed idle. Based on the proposed MAC protocol, we derive the stable throughput expressions of each primary user with secondary relaying. We also achieve the stable network constraints of relaying probability e, the feasible range of primary arrival rates and the maximum allowed secondary transmitting power which is to make a tradeoff between the stable throughput of the primary and secondary user. Numerical simulations show that secondary relaying can increase the primary and secondary throughput when designing an appropriate e.

  • ellipsis in simpler syntax
    The Oxford Handbook of Ellipsis, 2018
    Co-Authors: Peter W. Culicover, Ray Jackendoff
    Abstract:

    Same-Except is a fundamental domain-general Cognitive relation in which entities in proximity to one another are judged to be the Same, Except for some part or property where they differ. This relation can be attested in non-linguistic modalities such as vision, audition, and taste, and it plays an important role in non-linguistic categorization. The chapter shows that this relation is expressed linguistically by means of a wide range of devices, including (a) lexical expressions such as same and except, (b) contrastive stress, (c) anaphora (e.g. definite and indefinite NP anaphora and VP anaphora), (d) ellipsis (e.g. bare argument ellipsis, sluicing, gapping, and VP-ellipsis), and (e) fixed expressions such as vice versa. This approach thereby unifies the semantics of all these phenomena under a common account that is based on a domain-general Cognitive Principle. The approach is compared with accounts of ellipsis based on syntactic copying or deletion, showing that both approaches have their difficulties.

  • Same-except: A domain-general Cognitive relation and how language expresses it
    Language, 2012
    Co-Authors: Peter W. Culicover, Ray Jackendoff
    Abstract:

    Same-except is a fundamental, domain-general Cognitive relation in which entities in proximity to one another are judged to be the Same, Except for some part or property where they differ. This relation can be attested in nonlinguistic modalities such as vision, audition, and taste, and it plays an important role in nonlinguistic categorization. We show that this relation is expressed linguistically by means of a wide range of devices, including (a) lexical expressions such as same and except , (b) contrastive stress, (c) anaphora (e.g. definite and indefinite NP anaphora and VP anaphora), (d) ellipsis (e.g. bare argument ellipsis, sluicing, gapping, and VP ellipsis), and (e) fixed expressions such as vice versa and that goes for . Our approach thereby unifies the semantics of all of these phenomena under a common account that is based on a domain-general Cognitive Principle. We compare our approach with accounts of ellipsis based on syntactic copying or deletion, showing that although both approaches have their difficulties, the challenges to the copying/deletion approach are more severe.
