MetaSel - Meta-learning & Algorithm Selection ********************************************* ECAI-2014 Workshop, Prague, 19 August 2014 (date altered) http://metasel2014.inescporto.pt/
Announcement & Call for Papers Objectives This ECAI-2014 workshop will provide a platform for discussing the nature of algorithm selection which arises in many diverse domains, such as machine learning, data mining, optimization and satisfiability solving, among many others. Algorithm Selection and configuration are increasingly relevant today. Researchers and practitioners from all branches of science and technology face a large choice of parameterized machine learning algorithms, with little guidance as to which techniques to use. Moreover, data mining challenges frequently remind us that algorithm selection and configuration are crucial in order to achieve the best performance, and drive industrial applications. Meta-learning leverages knowledge of past algorithm applications to select the best techniques for future applications, and offers effective techniques that are superior to humans both in terms of the end result and especially in the time required to achieve it. In this workshop we will discuss different ways of exploiting meta-learning techniques to identify the potentially best algorithm(s) for a new task, based on meta-level information and prior experiments. We also discuss the prerequisites for effective meta-learning systems such as recent infrastructure such as OpenML.org. Many problems of today require that solutions be elaborated in the form of complex systems or workflows which include many different processes or operations. Constructing such complex systems or workflows requires extensive expertise, and could be greatly facilitated by leveraging planning, meta-learning and intelligent system design. This task is inherently interdisciplinary, as it builds on expertise in various areas of AI. The workshop will include invited talks, presentations of peer-reviewed papers and panels. The invited talks will be by Lars Kotthoff and Frank Hutter (to be confirmed). The target audience of this workshop includes researchers (Ph.D.'s) and research students interested to exchange their knowledge about: - problems and solutions of algorithm selection and algorithm configuration - how to use software and platforms to select algorithms in practice - how to provide advice to end users about which algorithms to select in diverse domains, including optimization, SAT etc. and incorporate this knowledge in new platforms. We specifically aim to attract researchers in diverse areas that have encountered the problem of algorithm selection and thus promote exchange of ideas and possible collaborations. Topics Algorithm Selection & Configuration Planning to learn and construct workflows Applications of workflow planning Meta-learning and exploitation of meta-knowledge Exploitation of ontologies of tasks and methods Exploitation of benchmarks and experimentation Representation of learning goals and states in learning Control and coordination of learning processes Meta-reasoning Experimentation and evaluation of learning processes Layered learning Multi-task and transfer learning Learning to learn Intelligent design Performance modeling Process mining Submissions and Review Process Important dates: Submission deadline: 25 May 2014 Notification: 23 June 2014 Full papers can consist of a maximum of 8 pages, extended abstracts up to 2 pages, in the ECAI format. Each submission must be submitted online via the Easychair submission interface. Submissions can be updated at will before the submission deadline. Electronic versions of accepted submissions will also be made publicly available on the conference web site. The only accepted format for submitted papers is PDF. Submissions are possible either as a full paper or as an extended abstract. Full papers should present more advanced work, covering research or a case application. Extended abstracts may present current, recently published or future research, and can cover a wider scope. For instance, they may be position statements, offer a specific scientific or business problem to be solved by machine learning (ML) / data mining (DM) or describe ML / DM demo or installation. Each paper submission will be evaluated on the basis of relevance, significance of contribution, technical quality, scholarship, and quality of presentation, by at least two members of the program committee. All accepted submissions will be included in the conference proceedings. At least one author of each accepted full paper or extended abstract is required to attend the workshop to present the contribution. A selection will be made of the best paper and runner ups, and these will be presented in the plenary session. The remainder of accepted submissions will be presented in the form of short talks and a poster session. All accepted papers, including those presented as a poster, will be published in the workshop proceedings (possibly as CEUR Workshop Proceedings). The papers selected for plenary presentation will be identified in the proceedings.

Tutorial on Metalearning and Algorithm Selection at ECAI-2014 ************************************************************* 18 August 2014 http://metasel.inescporto.pt/ Algorithm Selection and configuration are increasingly relevant today. Researchers and practitioners from all branches of science and technology face a large choice of parameterized algorithms, with little guidance as to which techniques to use. Moreover, data mining challenges frequently remind us that algorithm selection and configuration are crucial in order to achieve the best performance and drive industrial applications. Meta-learning leverages knowledge of past algorithm applications to select the best techniques for future applications, and offers effective techniques that are superior to humans both in terms of the end result and especially in a limited time. In this tutorial, we elucidate the nature of algorithm selection and how it arises in many diverse domains, such as machine learning, data mining, optimization and SAT solving. We show that it is possible to use meta-learning techniques to identify the potentially best algorithm(s) for a new task, based on meta-level information and prior experiments. We also discuss the prerequisites for effective meta-learning systems, and how recent infrastructures, such as OpenML.org, allow us to build systems that effectively advice users on which algorithms to apply. The intended audience includes researchers (Ph.D.'s), research students and practitioners interested to learn about, or consolidate their knowledge about the state-of-the-art in algorithm selection and algorithm configuration, how to use Data Mining software and platforms to select algorithms in practice, how to provide advice to end users about which algorithms to select in diverse domains, including optimization, SAT etc. and incorporate this knowledge in new platforms. The participants should bring their own laptops. _______________________________________________ uai mailing list uai@ENGR.ORST.EDU https://secure.engr.oregonstate.edu/mailman/listinfo/uai
