Special Issue Information

Dear Colleagues,

For many systems consisting of a group of interacting particles in motion, we often have experimental access only to measure (i) a part of the individual trajectories, and/or (ii) the spatial distribution of the group at particular times, but not the corresponding Hamiltonian/rules of interaction between individuals. Researchers then need to face the inverse problem of how to infer such rules from the partial observations available. There is a wide diversity of systems falling within this category, both physical (e.g., skyrmions, phonons, microbeads, or other quasiparticles or particles partially driven through thermal or external noise) and biological (e.g., in the analysis of single-cell trajectories or animal tracking). Due to the ubiquity of the problem, a large amount of learning/inference methods (based on Bayesian inference, information theory, machine learning, network theory, etc.) have been developed. The present issue is intended to provide both (i) an overview of the present state of the art, and (ii) some of the recent advances, in the field. Ideally, we want to illustrate the utility, range of application and advantages/disadvantages of the existing techniques, in order to promote a fruitful exchange of ideas among researchers from the aforementioned areas.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
