Call for Papers The Twentieth International Conference on Machine Learning Washington, DC USA August 21-24, 2003 The Twentieth International Conference on Machine Learning (ICML-2003) will be held in Washington D.C. August 21-24, 2003. The conference will bring together researchers to exchange ideas and report recent progress in the field of machine learning. TOPICS FOR SUBMISSION ICML-2003 welcomes submissions on all topics related to machine learning. In addition to the topics that traditionally are represented at machine learning conferences, we specifically encourage papers on the following topics: - Applications of machine learning, particularly: 1. exploratory research that describes novel learning tasks; 2. applications that require non-standard techniques or shed light on limitations of existing learning techniques; and 3. work that investigates the effect of the developers' decisions about problem formulation, representation or data quality on the learning process. - Analysis of learning algorithms that demonstrate generalization ability and also lead to better understanding of the computational complexity of learning. - The role of learning in spatial reasoning, motor control, and more generally in the performance of intelligent autonomous agents. - The discovery of scientific laws and taxonomies, and the induction of structured models from data. - Computational models of human learning. - Novel formulations of and insights into data clustering. - Learning from non-static data sources: incremental induction, on-line learning and learning from data streams. Submissions that demonstrate both theoretical and empirical rigor are especially encouraged. FORMAT OF THE CONFERENCE The conference will include one day of workshops and tutorials and three days of technical presentations, poster sessions and informal gatherings designed to foster discussion of research in machine learning. The conference will include both plenary and parallel tracks for the presentation of papers published in the conference proceedings. Speakers will also present their work at an evening poster session, which will allow conference attendees to discuss the work with the authors at greater length. In addition to presentations of refereed papers, the conference will include talks by several invited speakers. The conference will be co-located with KDD-2003 and COLT-2003. Details of the co-location will be announced shortly.
