Improved cosine similarity measures of simplified neutrosophic sets for medical diagnoses [PDF]

Artificial Intelligence in Medicine, 2015
In pattern recognition and medical diagnosis, similarity measure is an important mathematicaltool. To overcome some disadvantages of existing cosine similarity measures of simplified neutrosophicsets (SNSs) in vector space, this paper proposed improved cosine similarity measures of SNSs based oncosine function, including single valued neutrosophic ...

Comparative Analysis of Binary Similarity Measures for Compound Identification in Mass Spectrometry-Based Metabolomics

Metabolites, 2022
Compound identification is a critical step in untargeted metabolomics. Its most important procedure is to calculate the similarity between experimental mass spectra and either predicted mass spectra or mass spectra in a mass spectral library.

Cosine similarity measures for dual hesitant fuzzy sets [PDF]

Advances in Engineering Research, 2016
The Dual Fuzzy Sets (DHFSs), originated by Zhu and Xu (1), is a useful tool to deal with vagueness and ambiguity. In this paper, we propose one new measure called Cosine similarity measure for dual hesitant fuzzy sets, based on which the corresponding similarity measures can be obtained.

How to Normalize Co-Occurrence Data? An Analysis of Some Well-Known Similarity Measures [PDF]

, 2009
In scientometric research, the use of co-occurrence data is very common. In many cases, a similarity measure is employed to normalize the data. However, there is no consensus among researchers on which similarity measure is most appropriate for ...
