Speaker: Prof. Randy Goebel (department of Computing Science at the University of Alberta, in Edmkonton, Alberta, Canada) He is also vice president of the innovates Centre of Research Excellence (iCORE) at Alberta Innovates Technology Futures (AITF), chair of the Alberta Innovates Academy, and principle investigator in the Alberta Innovates Centre for Machine Learning. He received the B.Sc. (Computer Science), M.Sc. (Computing Science), and Ph.D. (Computer Science) from the Universities of Regina, Alberta, and British Columbia, respectively. At AITF, Randy is in charge of reshaping research investments (graduate student scholarships, research chairs, research centres). His research interests include applications of machine learning to systems biology, visualization, and web mining, as well as work on natural language processing, web semantics, and belief revision. Randy has experience working on industrial research projects in crew scheduling, pipeline scheduling, and steel mill scheduling, as well as scheduling and optimization projects for the energy industry in Alberta. Randy has held appointments at the University of Waterloo, University of Tokyo, Multimedia University (Malaysia), Hokkaido University (Sapporo), and has had research collaborations with DFKI (German Research Centre for Artificial Intelligence), NICTA (National ICT Australia), RWC (Real World Computing project, Japan), ICOT (Institute for New Generation Computing, Japan), NII (National Institute for Informatics, Tokyo), and is actively involved in academic and industrial collaborative research projects in Canada, Australia, Europe, and China. Abstract: The modern discipline of computer science has many facets, but what has clearly emerged in the last decade are three themes based on 1) rapidly accumulating volumes of data, 2) inter- and cross-disciplinary application of computer science to all scientific disciplines, and 3) a renewed interest in the semantics of complex information models, spanning a spectrum from semantic web, natural language, to multi-scale systems biology. This series of four lectures will attempt to knit together these three themes, by presenting the ideas that have emerged in their support: the rapid development and extension of machine learning theory and methods to help make sense of accumulating volumes of data, the application of computer science to nearly all scientific disciplines, especially those whose progress now necessarily relies on the management and interpretation of large data, and finally, the revival of a focus on semantics of information models based on data. Outline: Lecture 1: Connecting Advice Taking and Big Data Lecture 2: Structured inference and incomplete information Lecture 3: Natural Language Processing: Compressing Data to Models Lecture 4: Hypothesis Management with Symbols and Pictures Place: Lecture room 2010, 20th floor, National Institute of Informatics Date: 13:30pm-15:00pm, February 12, 20, 26, March 1, 2013 Lecture 1 Connecting Advice Taking and Big Data Tuesday, February 12, 2013, 13:30 - 15:00 A fundamental premise of Artificial Intelligence (AI) is the ability for a computer program to improve its behaviour by taking advice. Incremental accumulation of advice or knowledge has never been easier than today, when the rate of data capture is higher than ever before, and the management of big data and deployment of machine learning are coupled to help manage the transition from data to knowledge. This lecture uses simple technical concepts from nearly sixty years of AI, to identify some of the research challenges of managing big data, and exploiting knowledge emergent from big data. The goal is to find some important research priorities based on the motivation of the Advice Taker, and the current state of big data management and machine learning. Lecture 2 Structured inference and incomplete information Wednesday. February. 20, 13:30 - 15:00 If the foundation of Artificial Intelligence (AI) is the accumulation and use of knowledge, then a necessary stop is the structuring knowledge to be able to make inferences. The organization structures required to facilitate inference now span a broad spectrum of mathematical methods, including everything from simple propositional logic to sophisticated statistical and probabilistic inference. The two foundational components of computational inference are semantics of formal reasoning, and the development of reasoning methods to deal with incomplete information. This lecture reviews the foundational components of semantics and reasoning systems, including the development of goal-oriented reasoning based on abductive reasoning, the connection between logical and probabilistic systems, and especially how the architecture of reasoning systems can provide the basis for managing hypotheses in the face of incomplete information. Lecture 3 Natural Language Processing: Compressing Data to Models Tuesday. February. 26, 13:30 - 15:00 The problem of machine processing of natural language (NLP) has long been a research focus of artificial intelligence. This is partly because the use of natural language is easily conceived as a cognitive task requiring human-like intelligence. It is also because the rational structures for computer interpretation of language require the full suite of computational tools developed over the last hundred years (grammar, dictionaries, logic, parsing, inference, and context management). Most of the recent practical advances in NLP have arisen in the context of simple machine learning applied to large language corpora, to induce fragments of language models that provide the basis for interpretive and generative manipulation of language. These largely statistical models are arisen in what has been called the "pendulum swing" of NLP, in which statistical models have recently dominated those based on structural linguistics. In this lecture, we look at the concept of noisy corpora and their role in language models, including some interesting alternative sources of data for building language models. The applications range from complex language summary to the information extraction from medical, legal, and historical documents. Lecture 4 Hypothesis Management with Symbols and Pictures Friday. March. 1, 13:30 - 15:00 The current suite of Artificial Intelligence (AI) tools has provided a basis for sophisticated human-computer interfaces based on more than typing in language. In fact, one can develop multi-level representations that provide the basis for direct manipulation of visualizations. By constraining the repertoire of direct manipulations, one can enrich human computer interaction so that both humans and machines can understand and exploit visual interaction. This lecture shows how such direction manipulation requires a large repertoire of formal reasoning methods, and provides the sketch of formal framework and the problems arising in its development.

Calude (University of Auckland, NZ) and Elena Calude (Massey University, NZ) 講演要旨： Evaluating (or even guessing) the degree of complexity of an open problem, conjecture or mathematically proven statement is not an easy task not only for beginners, but also for the most experienced mathematicians. Is there a (uniform) method to evaluate, in some objective way, the difficulty of a mathematical statement or problem? The question is not trivial because mathematical problems can be so diverse. But, is there any indication that all, or most, or even a large part of mathematical problems have a kind of "commonality" allowing a uniform evaluation of their complexity? How could one compare a problem in number theory with a problem in complex analysis, a problem in algebraic topology or a theorem in dynamical systems? Surprisingly enough, such "commonalities" do exist for many mathematical problems. One of them is based on the possibility of expressing the problem in terms of (very) simple programs reducible to a (natural) question in theoretical computer science, the so-called "halting problem". A more general "commonality" can be discovered using the inductive type of computation, a computation more general the Turing computability. As a consequence, uniform approaches for evaluating the complexity of a large class of mathematical problems/conjectures/statements can be, and have been, developed. This talks reviews current progress and some open problems. ◆16時30分〜17時30分講演題目： The Kochen-Specker theorem and quantum randomness 講演者： Cristian S. Calude (University of Auckland, NZ) 講演要旨： The Kochen-Specker theorem shows the impossibility for a hidden variable theory to consistently assign values to certain (finite) sets of observables in a way that is noncontextual and consistent with quantum mechanics. If we require noncontextuality, the consequence is that many observables must not have pre-existing definite values. However, the Kochen-Specker theorem does not allow one to determine which observables must be value indefinite. In this talk we present an improvement on the Kochen-Specker theorem which allows one to actually locate observables which are provably value indefinite. Various technical and subtle aspects relating to this formal proof and its connection to quantum mechanics are discussed. This result is then utilized for the proposal and certification of a dichotomic quantum random number generator operating in a three-dimensional Hilbert space. ------------------------------------------------------------ 会場への道順： [中央大学後楽園キャンパスへのアクセスガイド] http://www.chuo-u.ac.jp/chuo-u/access/index_j.html http://www.chuo-u.ac.jp/chuo-u/access/access_korakuen_j.html [中央大学後楽園キャンパスマップ] http://www.chuo-u.ac.jp/chuo-u/campusmap/korakuen_j.html ------------------------------------------------------------

みなさま，東京大学の蓮尾です．あけましておめでとうございます．以前お知らせした ETAPS 併設ワークショップの HAS，締切が 1/21 に延長になりました．Post-proceeding ですので，論文の preliminary version でも大歓迎，とのことです．ご投稿を検討いただければ幸いです．どうかよろしくお願いいたします．それでは！蓮尾一郎 http://www-mmm.is.s.u-tokyo.ac.jp/~ichiro/ =========================== [Apologies for multiple copies] [Please note: submission deadline extended to January, 12] ************************************************************************************************************ ********* CALL FOR PAPERS Third Workshop on Hybrid Autonomous Systems (HAS 2013) A satellite event of European Joint Conferences on Theory and Practice of Software, ETAPS 2013 March 17, 2013, Rome, Italy http://www2.warwick.ac.uk/fac/sci/maths/people/staff/bujorianu/has2013/ ************************************************************************************************************ ********* SCOPE: The interest on autonomous systems is increasing both in industry and academia. Such systems must operate with limited human intervention in a changing environment and must be able to compensate for significant system failures without external intervention. The hybrid discrete-continuous models constitute appropriate models of autonomous systems . Hybrid systems have behaviours characterised by the interaction between continuous and discrete dynamics and research in the area is driven by several school of thoughts. One approach is mainly focussed on applications to automation systems and the models and methods are centred on the concept of hybrid automaton (deterministic or probabilistic). A distinct school of thought interprets hybrid systems as control systems with regime change. Such systems are highly adaptive and suitable for modelling autonomic behaviours. The most prominent models of this approach are the stochastic hybrid systems and the mixed logical and dynamical systems. There is a clear research opportunity to combine these approaches for developing models, methods, techniques, methodologies, tools and environments for autonomous systems engineering. This workshop brings together researchers interested in all aspects of autonomy and resilience of hybrid systems. TOPICS: Topics include (but are not limited to): Ø new modelling paradigms for autonomous systems; Ø verification and safety certification techniques; Ø modelling, analysis and control of hybrid systems; Ø uncertainty and stochastic modelling; Ø multi-agent systems; Ø algebraic and categorical methods; Ø interaction between hybrid modelling and complexity science; Ø reports on case studies and practical experiments; Ø autonomous systems in natural science (e.g. from biology, ecology, climate).

It is easily accessible via two airports: the main Chopin Airport, used by most international carriers, and the recently open Warsaw Modlin Airport (30 minutes away by rail), used by budget airlines. -- SATELLITE WORKSHOPS -- CALCO 2013 will be preceded by the CALCO Early Ideas Workshop, chaired by Monika Seisenberger (Swansea University). The workshop is dedicated to presentation of work in progress and original research proposals. PhD students and young researchers are particularly encouraged to contribute. Attendance at the workshop is open to all - it is anticipated that many CALCO conference participants will want to attend the CALCO Early Ideas workshop (and vice versa). A workshop dedicated to tools based on algebraic and/or coalgebraic principles, CALCO Tools, will be held alongside the main conference, chaired by Lutz Schr??der (Friedrich Alexander Universit??t Erlangen-N??rnberg). Papers of this workshop will be included in the CALCO proceedings. -- CALCO Early Ideas Overview -- The CALCO Early Ideas Workshop invites submissions on the same topics as the CALCO conference: reporting results of theoretical work on the mathematics of algebras and coalgebras, the way these results can support methods and techniques for software development, as well as experience with the transfer of the resulting technologies into industrial practice. The list of topics of particular interest is shown on the main CALCO 2013 page. CALCO Early Ideas presentations will be selected according to originality, significance, and general interest, on the basis of submitted 2-page short contributions. It can be work in progress, a summary of work submitted to a conference or workshop elsewhere, or work that in some other way might be interesting to the CALCO audience. A booklet with the accepted short contributions will be available at the workshop. Submissions will be handled via EasyChair https://www.easychair.org/conferences/?conf=calcoearlyideas2013 The use of LNCS style is strongly encouraged. After the workshop, authors will have the opportunity to submit a full 10-15 page paper on the same topic. The reviewing will be carried out by the CALCO Early Ideas PC, with the support of the CALCO PC. The volume of selected papers will be available online. Authors will retain copyright, and are also encouraged to disseminate the results by subsequent publication elsewhere. http://coalg.org/calco13/workshops.html#ei -- CALCO Early Ideas Dates -- 2-page short contribution submission: May 27, 2013 Notification for short contribution: June 24, 2013 Final short contribution due: July 15, 2013 CALCO Early Idead Workshop: September 2, 2013 10-15 page paper submission: October 15, 2013 Notification for paper: December 15, 2013 Final paper version due: January 15, 2014 -- CALCO Early Ideas Program Committee -- Bartek Klin, University of Warsaw, Poland John Power, University of Bath, UK Monika Seisenberger, Swansea University, UK (chair) -- CALCO-Tools Overview -- CALCO-Tools will take place on the same dates as the main CALCO conference, with no overlap between the technical programmes of the two events. Topics of interest include systems, prototypes, and tools developed specifically for the design, checking, execution, and verification of (co)algebraic specifications, but also tools targeting different application domains while making core or interesting use of (co)algebraic techniques. Tool submissions should not exceed 5 pages in LNCS format. The accepted tool papers will be included in the final proceedings of the conference. The tools should be made available on the web at the time of submission. Each submission will be evaluated by at least three reviewers; one or more of the reviewers will be asked to download and use the tool. At least one of the authors of each tool paper must attend the conference to demo the tool. http://coalg.org/calco13/workshops.html#tools -- CALCO-Tools Dates -- Paper submission: April 8, 2013 Author notification: May 6, 2013 Final version due: June 3, 2013 -- CALCO-Tools Programme Committee -- Einar Broch Johnsen, University of Oslo, Norway Mark Hills, CWI Amsterdam, The Netherlands Barbara K??nig, University of Duisburg-Essen, Germany Dorel Lucanu, Alexandru Ioan Cuza University, Romania Dominik Luecke, CWI Amsterdam, The Netherlands Till Mossakowski, DFKI, Germany Lutz Schr??der, Friedrich-Alexander Universit??t Erlangen-N??rnberg, Germany (chair) Alexandra Silva, Radboud University Nijmegen and CWI Amsterdam, The Netherlands -- FURTHER INFORMATION -- Queries related to submission, reviewing, and programme should be sent to the relevant conference or workshop chairs.
