• Some new de morgan picture operator triples in picture fuzzy logicSome new de morgan picture operator triples in picture fuzzy logic

    Conjunction operations (fuzzy t-norms) and disjunction operations (fuzzy t-conorms) are basic operators of the fuzzy logics [22, 13]. Picture fuzzy t-norms and picture fuzzy t-conorms firstly were defined and studied in 2015 [6, 9]. In this paper we give some algebraic properties of the picture fuzzy t-norms and the picture fuzzy t-conrms on pic...

  • A packet classification algorithm on multi-Way priority trieA packet classification algorithm on multi-Way priority trie

    The article has present the classification of packets in one direction in general and with the Priority trie [9] and JA trie [10] in particular. Based on the analysis of the advantages and disadvantages of each structure, we proposed a new packet classification algorithm based on Multi Way Priority {MWP trie structure. The accuracy of the algorit...

  • Characterizations for several classes of alternative codesCharacterizations for several classes of alternative codes

    The purpose of this paper was to deal with the development of the class of alternative codes. Four new classes of codes, which are subclasses of alternative codes, were introduced and considered. Some characteristics and relationships of these classes were proposed (Theorems 1-4). One of them provided us with a tool to check whether a given alter...

  • Hedges algebras and fuzzy partition problem for qualitative attributesHedges algebras and fuzzy partition problem for qualitative attributes

    Hedge algebra, a new and quite effective tool, can be used instead of the fuzzy theory in many cases due to the order structure on the set of natural language elements. This paper demonstrates this trend through the method of building the membership function to split fuzzy item sets in the fuzzy data mining problem. This is an important step tha...

  • Content based image retrieval using multiple features and pareto approachContent based image retrieval using multiple features and pareto approach

    This article formalizes properties of Pareto fronts in the search space in CBIR systems using multi features. The proposal carries out an efficiency for the classification engine. The Pareto method overcomes entanglements when CBIR systems use classification engine dealing with less labeled samples and real-time training data. It also overcome...

  • Learning interaction measure with relevance feedback in image retrievalLearning interaction measure with relevance feedback in image retrieval

    This paper proposes the method to aggregate multi-similarity measures based on relevance feedback in CBIR. In this approach, the overall similarity measure between the two images is calculated by non-additive aggregation from different individual similarity measure based on Choquet integral. The important weights are used in Choquet integral, whic...
