Professor at the Machine Learning Department and Language Technology Institute, Carnegie Mellon University, USA
Dr. Cohen's has a long-standing interest in statistical relational learning, the learnability of first-order logical representations, and in learning from data that has non-trivial structure. He has also worked on a number of tasks related to learning and language, such as information extraction, reasoning with automatically-extracted information, and question-answering making use of both structured and unstructured data. He holds seven patents related to learning, discovery, information retrieval, and data integration, and is the author of more than 200 publications.
Full Professor of Computer Science at the Faculty of Engineering, University of Siena, Italy
Marco Gori received the Ph.D. degree in 1990 from Università di Bologna, Italy, working partly at the School of Computer Science (McGill University, Montreal). In 1992, he became an Associate Professor of Computer Science at Università di Firenze and, in November 1995, he joint the Università di Siena, where he is currently full professor of computer science. His main interests are in machine learning with applications to pattern recognition, Web mining, and game playing. He is especially interested in bridging logic and learning and in the connections between symbolic and sub-symbolic representation of information. He was the leader of the WebCrow project for automatic solving of crosswords, that outperformed human competitors in an official competition which took place during the ECAI-06 conference. As a follow up of this grand challenge he founded QuestIt, a spin-off company of the University of Siena, working in the field of question-answering. He is co-author of the book "Web Dragons: Inside the myths of search engines technologies," Morgan Kauffman (Elsevier), 2006, and “Machine Learning: A Constrained-Based Approach,” Morgan Kauffman (Elsevier), 2018.
Dr. Gori serves (has served) as an Associate Editor of a number of technical journals related to his areas of expertise, he has been the recipient of best paper awards, and keynote speakers in a number of international conferences. He was the Chairman of the Italian Chapter of the IEEE Computational Intelligence Society, and the President of the Italian Association for Artificial Intelligence. He is a fellow of the IEEE, ECCAI, IAPR. He is in the list of top Italian scientists kept by the VIA-Academy.
Title: Learning and Inference with Constraints
Learning and inference are traditionally regarded as the two opposite, yet complementary and puzzling components of intelligence. In this talk I point out that a constrained-based modeling of the environmental agent interactions makes it possible to unify learning and inference within the same mathematical framework, which originates information-based laws of intelligence. The unification is based on the abstract notion of constraint, which provides a representation of knowledge granules gained from the interaction with the environment, as well as of supervised examples. The theory offers a natural bridge between the formalization of knowledge and the inductive acquisition of concepts from data. I give examples of learning and inferential processes in different environments by focusing on their natural integration and on the complementary role of data and knowledge representation.
Research Scientist at Facebook AI Research
Maximilian Nickel currently works as research scientist at Facebook AI Research in New York. Until 2016, he has been a postdoctoral fellow with the Laboratory for Computational and Statistical Learning (LCSL), hosted at the Center for Biological and Computational Learning (CBCL), Massachusetts Institute of Technology (MIT). In 2013, he received his Ph.D. summa cum laude from the Department for Informatics of the Ludwig-Maximilians-University of Munich under supervision of Volker Tresp. He received a diploma degree with honors in computer science from the Ludwig Maximilian University Munich in 2009.
