  • Jianji Wang,
  • Haiquan Zhao and
  • Jose C. Principe

20 May 2016

Entropy has been widely employed as a measure of variability for problems, such as machine learning and signal processing. In this paper, we provide some new insights into the behaviors of entropy as a measure of multivariate variability. The relatio...
