Research and Application for Grey Relational Analysis in Multigranularity Based on Normality Grey Number [PDF]
The Scientific World Journal, 2014 Grey theory is an essential uncertain knowledge acquisition method for small sample, poor information. The classic grey theory does not adequately take into account the distribution of data set and lacks the effective methods to analyze and mine big sample in multigranularity.
