Improved method for detecting weak abrupt information based on permutation entropy

As a dynamic detecting method for abrupt information, permutation entropy could effectively reflect the subtle change in time series data, which is also simple and can be computed conveniently. Based on the permutation entropy, some improved methods for detecting weak abrupt information hidden in ti...
