The method fails in bidimensional systems with long-range correlations.
It highlights the need for alternative entropy estimation techniques.
The critique emphasizes limitations of compression-based entropy estimation.
Abstract
In a recent Letter [1] a framework for estimating entropy was introduced and applied to one-dimensional and two-dimensional systems. In this Comment we show that the method is not well suited for estimating entropy in bidimensional systems presenting long-range correlations.
