Mass spectrometry is a powerful tool in chemistry research. A primary aim of data mining in chemistry is to try to obtain useful information from chemistry databases, and then classify the compounds using the useful samples features. Suffering from the traits of high dimension, and small sample in mass spectrometry data, in order to create models, it will(More)
Generally, some compounds identification methods use presently mass spectra similarity matching that cosine correlation and its composite measure are considered as similar approaches of mass spectra. Currently, several combination similarity measures had a much better performance, especially, Weighted-Cosine (WC) measure. In this work, we introduced random(More)
