- Go to the Sessions
- Event Details
Entropy 2021 has been a success!
We would like to thank our chair, organizers, speakers, sponsors, and all the attendees for making this a great meeting.
See you at the next edition!
Welcome from the Chair
The concept of entropy emerges initially from the scope of physics, but it is now clear that entropy is deeply related to information theory and the process of inference. Today, entropic techniques have found a broad spectrum of applications in all branches of science.
The conference will be organized into six sessions, which reflect the inter-disciplinary nature of entropy and its applications:
- Statistical Physics
- Information Theory, Probability and Statistics
- Thermodynamics
- Quantum Information and Foundations
- Complex Systems
- Entropy in Multidisciplinary Applications
The inter-disciplinary and multi-disciplinary nature of contributions from both theoretical and applied perspectives are welcome, including papers addressing conceptual and methodological developments, as well as new applications of entropy and information theory.
All accepted abstracts will be published in the proceedings of the conference. Moreover, participants are cordially invited to contribute with a full manuscript to Entropy Special Issue "Entropy: The Scientific Tool of the 21st Century".
Special Issue Submission deadline: 30 June 2021
Papers presented at the conference will be granted a 200 CHF discount!
The conference is sponsored by MDPI, the publisher of the open-access journal Entropy and follows the very successful meeting Entropy 2018: From Physics to Information Sciences and Geometry held in May 2018 in Barcelona, Spain.
We very much look forward to your participation.

sciforum-029325 | Confined Polymers as Self-Avoiding Random Walks on Restricted Lattices | , , , , , |
![]() |
![]() |
Show Abstract |
||||||||||||||||||||||||||||||||||||
Through extensive Monte Carlo simulations [1] we study the crystallization of freely-jointed chains of tangent hard spheres under conditions of extreme confinement. The latter is realized through the presence of flat, parallel and impenetrable walls in one or more dimensions [2]. Extreme confinement corresponds to the state where the inter-wall distance, in at least one dimension, approaches the monomer size. Results are presented for quasi-1D (tube-like) and quasi-2D (plate-like) polymer templates. In both cases we observe the entropy-driven formation of highly ordered regions of close-packed, slightly defective crystals of different orientations. In a second stage we map the confined polymer chains onto the self-avoiding random walk (SAW) model on restricted lattices [3]. We enumerate all possible chain configurations (or SAWs) on a specific regular lattice subject to spatial restrictions arising from confinement. Through this we can determine the conformational component of entropy and eventually predict the thermodynamic stability of each distinct polymer crystal. In parallel, we obtain approximate expression for the SAW behavior as a function of chain length, type of lattice, and level of confinement. We present a simple geometric argument to explain, to first order, the dependence of the number of restricted SAWs on the type of SAW origin. Restricted lattices correspond to the cubic (simple, body center and face center) crystal system and results are compared against the ones of the bulk (unrestricted) case.

Show Abstract |
||||||||||||||||||||||||||||||||||||
In this work, we study the problem of inferring a discrete probability distribution using both expert knowledge and empirical data. This is an important issue for many applications where the scarcity of data prevents a purely empirical approach. In this context, it is common to rely first on an a priori from initial domain knowledge before proceeding to an online data acquisition. We are particularly interested in the intermediate regime, where we do not have enough data to do without the initial a priori of the experts, but enough to correct it if necessary. We formalize expert knowledge as a set of priors, e.g. on the marginals or on the support of distribution. The expert distribution is defined as the distribution of the maximum entropy that satisfies the constraints set by the experts. In turn, empirical data is used to construct the empirical distribution. We present a new method for objectively choosing the weight to be given to the experts in relation to the data. We define our estimator as the projection of the experts on the confidence interval centered on the empirical distribution. This is the closest distribution from the experts which is consistent with the observed data. The confidence level is the unique parameter of this method. We show, both empirically and theoretically, that our proposed estimator is always more efficient than the best of the two models (expert or data alone) within a constant. Our estimator allows a bad a priori to be abandoned relatively quickly when the inconsistency of the data collected with the initial a priori is observed. At the same time, this same mixture makes it possible to keep the initial a priori if it is good. We prove empirically that our method outperforms a parametric Bayesian approach in such a task. |

sciforum-029276 | On Conditional Tsallis Entropy | , , | N/A |
![]() |
Show Abstract |
||||||||||||||||||||||||||||||||||||
Tsallis entropy, a generalisation of Shannon entropy that depends on a parameter alpha, provides an alternative way of dealing with several characteristics of nonextensive physical systems given that the information about the intrinsic fluctuations in the physical system can be characterized by the nonextensivity parameter alpha. It is known that as the parameter alpha approaches 1, the Tsallis entropy corresponds to the Shannon entropy. Unlike for Shannon entropy, but similarly to Rényi entropy (yet another generalisation of Shannon entropy that also depends on a parameter alpha and converges to Shannon entropy when alpha approaches 1), there is no commonly accepted definition for the conditional Tsallis entropy. In this work, we revisit the notion of conditional Tsallis entropy by studying some natural and desirable properties in the existing proposals: when alpha tends to 1, the usual conditional Shannon entropy should be recovered; the conditional Tsallis entropy should not exceed the unconditional Tsallis entropy; and the conditional Tsallis entropy should have values between 0 and the maximum value of the unconditional version. We also introduce a new proposal for conditional Tsallis entropy and compare it with the existing ones. |

sciforum-030038 | Predicting Human Responses to Syllogism Tasks Following the Principle of Maximum Entropy | , | N/A |
![]() |
Show Abstract |
||||||||||||||||||||||||||||||||||||
Syllogistic reasoning is one of the major research domains in cognitive science. Syllogisms are quantified semi-logical statements that consist of two premises, each relating two terms by one quantifier out of "All", "No", "Some", and "Some not". While one of the terms is mentioned in both premises, one is interested in what conclusion can be drawn about the relationship between the other two terms. For example, a well-formed syllogism task is "If all A are B and no B is a C, what, if anything, follows about the relationship between A and C?" While some syllogism tasks have a logically valid conclusion (in the example above, "No A is a C." is logically valid), some have not, like "If all A are B and some B are C, what follows about A and C?" In cognitive science, human responses to syllogism tasks are studied in order to better understand the human understanding of quantification and uncertainty in reasoning. In order to predict human responses to syllogism tasks, we develop a probabilistic model of syllogisms based on the principle of maximum entropy. For this, we translate the premises of syllogisms into probabilistic conditional statements and derive the probability distribution that satisfies the conditional probabilities while having maximal entropy. Then, we calculate the probabilities of all possible conclusions and compare them with the respective quantifier. As a prediction, we basically choose the option with the best matching. Based on empirical data, we show that our maximum entropy model predicts human responses better than established cognitive models. |

||||||||||||||||||||||||||||||||||||
About 160 years ago, the concept of entropy was introduced in thermodynamics by Rudolf Clausius. Since then, it has been continually extended, interpreted, and applied by researchers in many scientific fields, such as general physics information theory, chaos theory, data mining, and mathematical linguistics. Based on the original concept of entropy, many variants have been proposed. This paper presents a universe of entropies, which aims to review the entropies that had been applied to time series. The purpose is to answer important open research questions such as: How did each entropy emerge? What is the mathematical definition of each variant of entropy? How are entropies related to each other? What are the most applied scientific fields for each entropy? Answering these questions, we describe in-depth the relationship between the most applied entropies in time series for different scientific fields establishing bases for researchers to properly choose the variant of entropy most suitable for their data.
The number of citations over the past fifteen years of each paper proposing a new entropy, was accessed. The Shannon/differential, the Tsallis, the sample, the permutation, and the approximate entropy were the most cited entropies. Based on the ten categories with the most significant number of records obtained in the Scopus categories, the areas in which the entropies are more applied are computer science, physics, mathematics, and engineering. From the top ten, the application area with less citations of papers proposing new entropies is the medical category. |
Registration
The registration fee for Oral Presentation participants is €100 per participant, and the fee for Poster Presentation (just shown in a slide show & as a downloadable single slide) participants is €50 per participant. Those attending without any submissions will be charged €25 per participant; this is an optional fee, but is necessary if you wish to join live sessions during Entropy 2021. The authors (Invited speakers, Oral Presentation, Poster Presentation) will not pay an extra fee for the live sessions.
Finally, only registered authors will be able to apply for the Conference Awards, and the 200 CHF discount on the publication fees for the special issue "Entropy: The Scientific Tool of the 21st Century", in the journal Entropy.
Participation to the conference is considered final only once the registration fee has been paid. Registration by at least one author per paper, denoted as Covering Author, is required to cover participation and publication of any submission. Covering Author registration deadline is 7 April 2021. Your abstract and submission will be withdrawn if you do not complete the registration by this date.
Authors with multiple contributions: Please note that one author registration will cover 3 accepted contributions at most.
When registering, please provide us with your institutional email address. This will accelerate the registration process. If you are registering several people under the same registration, please do not use the same email address for each person, but their individual institutional email addresses. Please note that, submission and registration are two different processes. During registration, if possible, use the same email address you used to submit your abstract(s). Otherwise, leave us a comment in the registration form, providing the email address used during the submission process.
Certificate of Attendance: Upon request, the participants of the event will receive an electronic Certificate of Attendance by email once the event is concluded.

About Oral presentation:
The slot for Oral presentation is 15 min. We would advise to prepare your presentation to a maximum of 10-12 min to leave at least 3 min for Q&A. The video of your presentation should be saved in mp4 format – this will be used in case of bad connection. -
About Poster presentation:
We would recommend to:
(1) prepare one single Poster that should be A0 size, vertical – it can then be made available as a PDF printable document. There are no restrictions / template available. Thus, authors can choose the font type and size that better shows your research. We would also recommend to include a header – about 15 cm height with logos (corresponding to the Conference name, Title of the poster and Authors’ names, and your affiliation(s).
(2) prepare 2 or 3 slides that can be commented by you and saved as a video presentation or a short video – mp4 format. Anyway, this must not exceed 2-3 min to play.
