Photometric Redshifts with Copula Entropy
Jian Ma
In this paper we propose to apply copula entropy (CE) to photometric redshifts. CE is used to measure the correlations between photometric measurements and redshifts and then the m…
Two-Sample Test with Copula Entropy
Jian Ma
In this paper we propose a two-sample test based on copula entropy (CE). The proposed test statistic is defined as the difference between the CEs of the null hypothesis and the alt…
System Identification with Copula Entropy
Jian Ma
Identifying differential equation governing dynamical system is an important problem with wide applications. Copula Entropy (CE) is a mathematical concept for measuring statistical…
Identifying Time Lag in Dynamical Systems with Copula Entropy based Transfer Entropy
Jian Ma
Time lag between variables is a key characteristics of dynamical systems in different fields and identifying such time lag is an important problem in complex systems with many appl…
