Generalized weighted permutation entropy
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2022 A novel heuristic approach is proposed here for time series data analysis, dubbed Generalized weighted permutation entropy, which amalgamates and generalizes beyond their original scope two well established data analysis methods: Permutation entropy and Weighted permutation entropy.

Composability and generalized entropy [PDF]
Physics Letters A, 1999 We address in this paper how tightly the composability nature of systems: $S_{A+B} = (S_A, S_B)$ constrains definition of generalized entropies and investigate explicitly the composability in some ansatz of the entropy form.

Generalized Entropies, Variance and Applications [PDF]
Entropy, 2020 The generalized cumulative residual entropy is a recently defined dispersion measure. In this paper, we obtain some further results for such a measure, in relation to the generalized cumulative residual entropy and the variance of random lifetimes. We show that it has an intimate connection with the non-homogeneous Poisson process.

Streaming generalized cross entropy [PDF]
Soft Computing, 2019 We propose a new method to combine adaptive processes with a class of entropy estimators for the case of streams of data. Starting from a first estimation obtained from a batch of initial data, model parameters are estimated at each step by combining the prior knowledge with the new observation (or a block of observations).

Methods to Calculate Entropy Generation. [PDF]
Entropy (Basel)Entropy generation, formulated by combining the first and second laws of thermodynamics with an appropriate thermodynamic potential, emerges as the difference between a phenomenological entropy function and a reversible entropy function. The phenomenological entropy function is evaluated over an irreversible path through thermodynamic state space via ...
