Beyond tf-idf and Cosine Distance in Documents Dissimilarity Measure

2015
In vector space model, different types of term weighting schemes are used to adjust bag-of-words document vectors in order to improve the performance of the most widely used cosine distance. Even though the cosine distance with some term weighting schemes result in more reliable (dis)similarity measure in some data sets, it may not perform well in ...

Modified Cosine Similarity Measure between Intuitionistic Fuzzy Sets

2012
Similarity of intuitionistic fuzzy sets (IFSs) is an important measure to indicate the similarity degree between IFSs. Recently, Ye (2011) proposed a similarity measure between IFSs based on the cosine concept. Although this cosine similarity measure has good concept and merit, the measure is not satisfied the definition of a similarity between IFSs ...

Iris Recognition Using Discrete Cosine Transform and Relational Measures

2015
Iris is one of the most discriminative biometric trait because it has random discriminating texture which does not change much, over a long time period. They are unique for all individuals, even for twins and the left and right eyes of the same individuals. In this paper an iris recognition system is presented that does iris segmentation, normalization,

COSINE ENTROPY AND SIMILARITY MEASURES FOR FUZZY SETS

2014
In the present paper, based on the cosine function, a new fuzzy entropy measure is de ned. Some interesting properties of this measure are analyzed. Furthermore, a new fuzzy similarity measure has been proposed with its elegant properties. A relation between the proposed fuzzy entropy and fuzzy similarity measure has also been proved.
