Recognition of Tea Taste Signal Based on Rough Set.

The discretization method of continuous attributes based on decision attributes which is discussed in document [3] can't consider some special breakpoints very carefully. The modified algorithm on discretization given in this paper will improve the recognition accuracy and decrease the number of breakpoints. Experiment one gives the result about recognition of tea taste signal based document [3]'s algorithm. Experiment two gives the result about recognition of tea taste signal based on modified algorithm on discrtization method. By comparison with experiment one and experiment two testified the superiority of algorithm in this paper.
