Submission
All papers should be submitted to entropy@mdpi.org with copy to the guest editor. To be published continuously until the deadline and papers will be listed together at the special websites. Both, research articles and review articles are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editors for announcment on this website.
Submitted papers should not have been published previously, nor be under consideration for publication elsewhere. All papers are refereed through a peer-review process. A guide for authors, sample copies and other relevant information for submitting papers are available on the Instructions for Authors page. Entropy is an international peer-reviewed quarterly journal published by Molecular Diversity Preservation International.
Please visit the Instructions for Authors page before submitting a paper. Open Access publication fees are 800 CHF per paper. English correction fees (250 CHF) will be added in certain cases (1050 CHF per paper for those papers that require extensive additional formatting and/or English corrections.).

Title: Possible roles for thermodynamic laws in a cosmic genesis
Author: Akinbo Ojo
Affiliation: Standard Science Centre, P.O. Box 3501, Surulere, Lagos, Nigeria
Abstract: Thermodynamic laws have been found applicable to many systems within the universe. But are they applicable to the universe itself as a whole system? Based on the assumption that they are, we are able to propose a modality rooted in quantum physics which can permit astronomical increases in the entropy, phase-space volume and thus the number of position and momentum coordinates that are available in a system, in spite of any prevailing adiabatic conditions. We conclude that a study of the thermodynamic consequences of energy introduction into a state at low or absolute zero temperature may increase our understanding of any possible cosmic genesis.

Title: Maximum Entropy Parameter Learning at Elevated Training Temperature
Authors: Ronny Melz
Abstract: ForMaximum Entropy (ME) parameter inference, the Improved Iterative Scaling algorithm (IIS) is often preferred over Generalized Iterative Scaling (GIS) due to its better convergence properties. But effectively, IIS requires the feature sum for each training event to be drawn from quite a limited, finite set of discrete values to allow for an efficiently computable parameter update step. Quite some generality of ME models is lost by requiring the feature functions to sum to discrete values. We re-interpret the maximum feature sum (originally determined by the GIS convergence proof) as an inverse “training temperature”, i.e. an additional free hyper parameter of the model. We provide empirical evidence that GIS outperforms IIS for suitable values of the training temperature, especially in the most interesting early iterations, despite its less complex implementation.
