[SIPTA] 3rd Call for papers: DARe at LPNMR-19
by Ivan José Varzinczak Feb. 12, 2019

Feb. 12, 2019

* Apologies if you receive multiple copies of this call * ============================== Call for Papers DARe at LPNMR 2019 Date: June 3 or 4 2019 (TBC) Philadelphia, USA *** Deadline: 19 March 2019 *** ============================== The Fifth International Workshop on "Defeasible and Ampliative Reasoning" (DARe) https://sites.google.com/view/dare-19/ collocated with LPNMR 2019 -- Workshop Description and Aims -- Classical reasoning is not flexible enough when directly applied to the formalisation of certain nuances of human quotidian decision making. These involve different kinds of reasoning such as reasoning with uncertainty, exceptions, similarity, vagueness, incomplete or contradictory information and many others. It turns out that everyday reasoning usually shows the two salient intertwined aspects below: * Ampliative aspect: augmenting the underlying reasoning by allowing more conclusions. In practical contexts, this amounts to the ability to make inferences that venture beyond the scope of the premises, somehow in an unsound but justifiable way. Prominent examples are (i) default reasoning: jumping to conclusions deemed as plausible 'by default', i.e., in the absence of information to the contrary, like applying negation as failure or adopting the closed-world assumption; (ii) inductive and abductive reasoning: taking chances in drawing conclusions that implicitly call for further scrutiny or tests by empirical observations, like in making inductive hypotheses in scientific theories or finding abductive explanations in forensics, and (iii) analogical reasoning: extrapolating from very few examples (in the worst case only one) on the basis of observable similarities or dissimilarities. * Defeasible aspect: curtailing the underlying reasoning by either disregarding or disallowing some conclusions that somehow ought not to be sanctioned. In practice, this amounts to the ability to backtrack one's conclusions or to admit exceptions in reasoning. Some examples of this are (i) retractive reasoning: withdrawing conclusions that have already been derived, like in belief contraction or in negotiation, and (ii) preemptive reasoning: preventing or blocking the inference of some conclusions by disallowing their derivation in the first place, like in dealing with exceptional cases in multiple inheritance networks and in regulatory systems. Several efforts have been put into the study and definition of formalisms within which the aforementioned aspects of everyday reasoning could adequately be captured at different levels. Despite the progress that has been achieved, a large avenue remains open for exploration. Indeed, the literature on non-monotonic reasoning has focused almost exclusively on defeasibility of argument forms (conditionals), whereas belief revision paradigms are restricted to an underlying classical (Tarskian) consequence relation. Moreover, even if some of the issues related to uncertainty in reasoning have been studied using probabilistic approaches and statistical methods, their integration with qualitative frameworks remain a challenge. Finally, well-established approaches are largely based on propositional languages or haunted by the undecidability of full first-order logic. Modern applications require formalisms with a good balance between expressive power and computational complexity. DARe aims at bringing together researchers and practitioners from core areas of artificial intelligence, cognitive sciences, philosophy and related disciplines to discuss these kinds of problems and relevant results in a multi-disciplinary forum. The goal of the workshop is to present latest research developments, to discuss current directions in the field, and to collect first-hand feedback from the community. -- Scope of the Workshop -- DARe welcomes contributions on all aspects of defeasible and ampliative reasoning such as (but not limited to): - Abductive and inductive reasoning - Explanation finding, diagnosis and causal reasoning - Inconsistency handling and exception-tolerant reasoning - Decision-making under uncertainty and incomplete information - Default reasoning, non-monotonic reasoning, non-monotonic logics, conditional logics - Specific instances and variations of ampliative and defeasible reasoning - Probabilistic and statistical approaches to reasoning - Vagueness, rough sets, granularity and fuzzy-logics - Philosophical foundations of defeasibility - Empirical studies of reasoning - Relationship with cognition and language - Contextual reasoning - Preference-based reasoning - Analogical reasoning - Similarity-based reasoning - Belief dynamics and merging - Argumentation theory, negotiation and conflict resolution - Heuristic and approximate reasoning - Defeasible normative systems - Reasoning about actions and change - Reasoning about knowledge and belief, epistemic and doxastic logics - Ampliative and defeasible temporal and spatial reasoning - Computational aspects of reasoning with uncertainty - Implementations and systems - Applications of uncertainty in reasoning -- Submission Requirements -- We invite submissions of papers presenting original research results or position statements.

[SIPTA] Bayes@Lund 2019 - Invitation and Call for Presentations
by TROFFAES Feb. 11, 2019

Feb. 11, 2019

*Please disseminate where appropriate.* Bayes(a)Lund 2019 – a Mini-conference on Bayesian Methods at Lund University, 7th of May, 2019 You are welcome to participate in the sixth edition of Bayes(a)Lund! The purpose of this conference is to bring together researchers and professionals working with or interested in Bayesian methods. Bayes(a)Lund aims at being accessible to researchers with little experience of Bayesian methods while still being relevant to experienced practitioners. The focus is on how Bayesian methods are used in research and in the industry, what advantages Bayesian methods have over classical alternatives, and how the use and teaching of Bayesian methods can be encouraged. (see last year's conference<https://bayesat.github.io/lund2018/bayes_at_lund_2018.html> for what to expect). The conference will take place at Lund University, Sweden on the 7th of May 2019 starting at 9.00 and ending at 17.00. It will include contributed talks and invited presentations. This year we are more than pleased to have Sharon Bertsch McGrayne as an invited speaker. She is the author of the The Theory That Would Not Die<http://www.mcgrayne.com/the_theory_that_would_not_die__how_bayes__rule_crac…>, the bestselling book that describes the rise and fall and rise again of Bayesian statistics. For more information and how register, please see the conference web site<https://indico.esss.lu.se/event/1191/>. Call for Presentations We invite you to submit a talk or short tutorial to Bayes(a)Lund 2019 on a topic related to Bayesian methods in research as well as in a non-academic context, including, but not restricted to: · Case studies. Have you used Bayesian methods in your work? Describe what you did, and how it worked out. · Method development. Are you developing novel Bayesian methods or software that you want to share? · Teaching Bayes. Do you have experiences teaching or introducing Bayesian methods? What were the challenges, and do you have any useful tips? Each accepted speaker is given 20 minutes and, as the audience will be highly heterogeneous from different disciplines and from within and outside academia, the talk is expected to be accessible and engaging for a multidisciplinary audience. Alternatively, short tutorials are 10/20/30 minutes long tutorials where you introduce the audience to a tool, package or methodology you find useful. It doesn’t need to be something you’ve developed, just something you want to show the audience! For more information on how to submit a talk proposal please see here<https://indico.esss.lu.se/event/1191/abstracts/>. We hope to see you there! All best, The committee Ullrika Sahlin, Rasmus Bååth, Alex Holmes, and Jakob Lavröd

Re: [SIPTA] Fwd: Are there imprecise analogues of pseudo-random number generators?
by Marco Cattaneo Nov. 17, 2018

Nov. 17, 2018

Dear all, I can only recommend the paper by Gert and Jasper, which includes several deep results about infinite sequences of 0's and 1's. However, as far as I understand, Marshall is interested in finite sequences of 0's and 1's that are generally accepted as "random", like the ones generated by PRNGs. Unfortunately, I do not know of any non-artificial way of generating such sequences for imprecise probabilities. Since iid sequences of 0's and 1's have relative frequencies that converge due to the law of large numbers, sequences for which the relative frequencies do not converge can be artificially obtained by dropping one (or both) of the two i's in iid. For instance, a sequence with relative frequency of 1's tending to oscillate between 0.6 and 0.8 can be obtained by keeping independence but varying the probability of 1's according to the following sequence: once 0.6, two times 0.9, six times 0.5, 18 times 0.9, 54 times 0.5, 162 times 0.9, and so on (alternating between 0.5 and 0.9 with block lengths increasing by threefold each time). By adding some randomness to the sequence of probabilities, this could be made less artificial, but I do not know of any work in which this kind of ideas is explicitly developed. Best wishes, Marco -----Original Message----- From: SIPTA <sipta-bounces(a)idsia.ch> On Behalf Of Gert De Cooman Sent: Tuesday, November 13, 2018 7:04 PM To: Dr. Alessandro Antonucci <alessandro(a)idsia.ch> Cc: sipta(a)idsia.ch Subject: Re: [SIPTA] Fwd: Are there imprecise analogues of pseudo-random number generators? My reply to Alessandro, building on my previous message : Precise randomness is more than convergence of the sample mean for the sequence – which is what you use in your argument – it implies also convergence to the same limit of the sample mean for any (computably selected) subsequence. (This is the notion of computable stochasticity, which is still weaker than randomness, and therefore implied by it). It is easy to see that if the extreme points are visited in a computable fashion, we can computably select subsequences whose sample mean will converge to any of the extreme points. Or arbitrarily close to any convex mixture of them. So the sequence will then not be precisely random, contrary to what you suggest. Computable randomness (in the precise case) of a sequence is the stronger property that unless you use the exact precise probability as your model for betting on the sequence of digits, you can be made to lose an unbounded amount of money by someone who bets against you using some computable strategy. It is this (martingale-theoretic) characterisation of (computable) randomness that we generalise to the imprecise case in our paper.

It is easy to see that if the extreme points are visited in a computable fashion, we can computably select subsequences whose sample mean will converge to any of the extreme points. Or arbitrarily close to any convex mixture of them. So the sequence will then not be precisely random, contrary to what you suggest. Computable randomness (in the precise case) of a sequence is the stronger property that unless you use the exact precise probability as your model for betting on the sequence of digits, you can be made to lose an unbounded amount of money by someone who bets against you using some computable strategy. It is this (martingale-theoretic) characterisation of (computable) randomness that we generalise to the imprecise case in our paper.

Re: [SIPTA] Fwd: Are there imprecise analogues of pseudo-random number generators?
by Gert De Cooman Nov. 13, 2018

Nov. 13, 2018

Dear Marshall I refer to our paper about imprecise randomness (Computable randomness is inherently imprecise, De Cooman and De Bock) in the latest ISIPTA proceedings: https://biblio.ugent.be/publication/8531435/file/8531437.pdf In the paper we show that non-stationarity is indeed a source of imprecise randomness. We also prove a number of convergence results. All this for sequences of 0-1, which is the simplest case. We show, for instance, that alternating between a two un-fair coins with probabilities p and q for heads (in a deterministic fashion) will produce an imprecise random sequence of 0’s and 1’s with characterising probability interval [p,q]. The meaning of this is explained in the paper, but the underlying idea is that anyone using an interval betting model that does not include [p,q] - so for instance a precise r in this interval - can be made to lose an infinite amount of money in an infinite sequence of betting events on the digits in the sequence (using a computable strategy); and anywhere who uses a betting model that includes [p,q] is immune to such computable strategies. So this suggests an algorithm in the more general case: use an algorithm that visits the externe points of a credal set deterministically (eg, cyclically) , and for each visit to an extreme point, use the corresponding random generator to generate an outcome. Whether this also works in the case of more than two possible outcomes, still remains to be investigated, however.

[SIPTA] Fwd: Are there imprecise analogues of pseudo-random number generators?
by Alessandro Antonucci Nov. 13, 2018

Nov. 13, 2018

Dear Marshall, For an imprecise subjectivist “the imprecision is in the eye of the learner”. A non-stationary RNG can jump from one sampling distribution to another but, again, this is done according to another (second-order) distribution. The sample will be indistinguishable from another one sampled from the marginal of that hierarchical model. The imprecision level is basically a parameter of your learning algorithm (e.g., s for the IDM, alpha for likelihood-based approachs), but not something you might learn from your data. These are my two cents.

I would like to ask a theoretical and practical question. (No conference announcement here!) tl;dr: Are there imprecise analogues of pseudo-random number generators? If that question doesn't make sense, please feel free to read on, with my thanks for doing so. (Sorry the following is so long; I was worried that what I was asking would be unclear otherwise.) I am interested in imprecise chance, that is, objective imprecise probability; this idea has been discussed in different ways by Terrence Fine and his colleagues, Marco Cattaneo, Luke Glynn, Alan Hajek, Suppes and Zanotti, Stephan Hartmann, Igor Gorban, and probably others. In an agent-based model, (precise) chance can be modeled using a PRNG. Can this be generalized to base an ABM on a model of imprecise chance? I had thought this would be impossible, but now I am not so sure. A good PRNG such as a Mersenne Twister is of course not truly chancy, and its output even has low Kolmogorov complexity, but it's still a good way to model chance in many contexts. Why couldn't imprecise chance be modeled in an ABM using a deterministic algorithm as well? What would the output of a pseudo imprecise random number generator (PIRNG) look like? Well, suppose one wrote a function that used a normal PRNG to generate 0's and 1's with probability 0.7 for 1. Then over most large sets of outputs, we would find the frequency of 1 to be close to 0.7, and as we increased the size of such a set, the frequency would usually get closer to 0.7 Similarly, using a PIRNG, one ought to be able to write a function that generates 0's and 1's with (for example) an interval probability of [0.6, 0.8] for 1. Then over most large lets of outputs, the frequency of 1 should lie in or near [0.6, 0.8], and as we increased the size of such a set, the frequency would remain near [0.6, 0.8] but would usually wander without settling down to any precise value within that interval. Are there known algorithms that might have this kind of behavior? Or could this kind of behavior be simulated using PRNGs for sequences that are not extremely long? i.e. maybe one can write a function using a PRNG such that over the not-too-long-run, sequences would appear to be imprecisely chancy, but they would eventually settle down to precise values in the very very long run. That might be good enough for some ABMs. Or am I just confused? (I think this is not unlikely.) Any suggestions about what sort of literature I should look at or what kinds of keywords to search on would be welcome. [In some parts of Fierens, Rego, and Fine's "A frequentist understanding of sets of measures" (2009), it sounds as if such a class of algorithms might be described, at least in a loose, general way, but if that is so, I have not understood the article well enough to see how what's given there does so. Their model uses sequence specified to be of intermediate Kolmogorov complexity, which itself seems like a difficult thing to generate.] Thank you!

Oct. 19, 2018

Papers related to imprecise probabilities are welcome at this series of workshops ________________________________________ Welcome to 12th International Workshop on Constraint Programming and Decision Making CoProD'2019 June 17, 2019 -- Lafayette, Louisiana CoProD'19 is the twelfth edition of CoProD http://coprod.constraintsolving.com/. It will be held in Lafayette, Louisiana, USA on June 17, 2018 (exact location TBA), right before the 2019 IFSA World Congress and NAFIPS Annual Conference IFSA/NAFIPS'2019 (June 18-22, 2019, Lafayette, Louisiana), see https://interval.louisiana.edu/IFSA-NAFIPS/ Constraint programming techniques are important components of intelligent systems. They constitute a declarative and efficient methodology to represent and solve many practical problems. They have been applied successfully to a number of fields, such as scheduling of air traffic, software engineering, networks security, chemistry, and biology. Despite the proved usefulness of these techniques, they are still under-utilized in real-life applications. One reason is the perceived lack of effective communication between constraint programming experts and domain practitioners about constraints, in general, and their use in decision making, in particular. Registration: Registration will be collected on site and will be about $30, to cover coffee breaks and room and equipment rental Objectives of CoProD: * To present advances in constraint solving, optimization, and related topics; * To develop a network of researchers interested in constraint techniques, in particular researchers and practitioners that use numeric and symbolic approaches (or a combination of them) to solve constraint and optimization problems; * To address the gap between the great capacity of these techniques and their limited use. CoProD aims at encouraging presentation and discussion of on-going work. In particular, please note that there is room for presentation of ideas, as opposed to results only. It also aims at facilitating networking opportunities as well as cross-fertilization between the approaches used in the different attending communities. Therefore, besides active researchers in decision making and constraint programming techniques, we expect to have a wide attendance and participation of domain scientists -- whose input is highly valued in this workshop.

FYI, papers on fuzzy-valued imprecise probabilities are always welcome. This time, the conference has a strong emphasis on relation with interval techniques, so papers on interval-valued probabilities are also welcome. ________________________________________ From: Ralph Baker Kearfott <rbk5287(a)louisiana.edu> Sent: Thursday, October 18, 2018 7:46 AM IFSA-NAFIPS 2019 Call for papers 2019 INTERNATIONAL FUZZY SYSTEMS ASSOCIATION WORLD CONGRESS and the 2019 NORTH AMERICAN FUZZY INFORMATION PROCESSING SOCIETY ANNUAL MEETING Jun3 18-22, 2019 Lafayette, Louisiana Hosted by the North American association, this biennial event brings together participants from all national and regional fuzzy system associations. IFSA-NAFIPS 2019 will be hosted at the Wyndham Garden near Vermilion Bayou in Lafayette, Louisiana, the center of Cajun culture and cuisine. Topics will include implementation and applications of fuzzy information processing technology, associated mathematical analysis, comparison with alternative rough set, statistical, and interval techniques, and, generally, other topics related to fuzzy sets. Further information can be found at: https://interval.louisiana.edu/IFSA-NAFIPS/ This conference will be held a week before the New Orleans FUZZ-IEEE conference. New Orleans is 140 miles (225 kilometers) from Lafayette, a 2.5 hour drive, from Lafayette, and we plan to arrange post-conference charter buses from Lafayette to New Orleans. Participants will thus have leverage to double their professional and cultural experience. Deadlines (extended): Special session and workshop proposals: December 1, 2018 Paper submission: January 15, 2019 A number of special sessions have already been accepted, and keynote speakers have already agreed.

[SIPTA] 2008 SIPTA Summer School site moving to sipta.org; request for checks and missing materials
by Erik Quaeghebeur Sept. 13, 2018

Sept. 13, 2018

Dear colleagues, The website of the SIPTA Summer School 2008 has been available at <http://www.lirmm.fr/SIPTASchool08/school.htm>, but to ensure long-term preservation, it is moving to <http://www.sipta.org/ssipta08/>. I would kindly like to request the following: 1. Please update links to this site on webpages you or your colleagues manage. 2. Please check the site (and compare to the one at the previous location) to see if something went wrong during the move (we are aware the videos are missing at both locations). 3. Please check whether you have local copies of missing materials (specifically, the videos). In case you come up with something for points 2. and 3. or any other relevant matter, please contact Fabio (in Cc) and myself by reply email. Posterity will be in your debt. After allowing some time for your input, we will inform the maintainers of the previous location that the move has been done. Then they can install a permanent redirect at the old address and, if they choose, later on remove it from their server. Best regards, Erik -- https://ac.erikquaeghebeur.name

----- Messaggio inoltrato da massimo.campanino(a)unibo.it ----- Data: Thu, 6 Sep 2018 15:03:00 +0000 Da: Massimo Campanino <massimo.campanino(a)unibo.it> Oggetto: [Random] I: Avviso di seminario A: "Random(a)fields.dm.unipi.it" <Random(a)fields.dm.unipi.it> Il giorno 20 settembre alle ore 14 nell'Aula Seminario 2 del Dipartimento di Matematica dell'Università di Bologna in piazza Porta S. Donato 5 il prof. Pietro Rigo del Dipartimento di Matematica dell'Università di Pavia terrà un seminario dal titolo: CLASSICAL VERSUS COHERENT CONDITIONAL PROBABILITIES ABSTRACT: The standard (Kolmogorovian) notion of conditional probability is compared with the (de Finettian) notion based on the coherence principle. Each notion has both merits and drawbacks, and the talk aims to highlight them with special attention to the connection points. Various results, both old and new, are discussed and some open problems are mentioned. The talk is split into four parts. (i) Classical (Kolmogorovian) conditional probabilities; (ii) Disintegrability; (iii) Coherent (de Finettian) conditional probabilities; (iv) Some statistical implications. _______________________________________________ Random mailing list Per informazioni e per disiscriversi: https://fields.dm.unipi.it/listinfo/random Per contattare gli amministratori: random-admin(a)fields.dm.unipi.it Per inviare un messaggio alla mailing list: Random(a)fields.dm.unipi.it Archivio dei messaggi inviati: https://fields.dm.unipi.it/pipermail/random ----- Fine messaggio inoltrato. -----
