[This call might be of particular interest to you if you are already attending IEEE CEC 2017 or CPAIOR 2017. Apologies for multiple postings.] Dear Colleagues, We would like to invite you to participate the Workshop on Data Science meets Optimization which will take place colocated with IEEE Congress on Evolutionary Computation (CEC) 2017 in Donostia - San Sebastian, Spain and 14th International Conference on Integration of Artificial Intelligence and Operations Research Techniques in Constraint Programming (CPAIOR 2017) in Padova, Italy on the 5th of June, 2017. We will have the following keynote speakers. CPAIOR 2017: Prof. Dr. Tias Guns, Vrije Universiteit Brussel CEC 2017: Prof. Dr. Holger Hoos, Universiteit Leiden This workshop is an activity of EURO working group on Data Science meets Optimization, but is open to everyone. The general scope of the stream is the usage of data science methods, including machine learning and statistics, to improve the effectiveness of optimisation and metaheuristics and vice versa. The broader aim of the workshop is to encourage interaction between optimisation and data science; bringing together researchers and practitioners from related fields, such as Operational Research (OR), Artificial Intelligence, Mathematical Sciences and Computer Science. In order to present at the workshop please send us a title and abstract/paper via an email to "info [ATT] <http://ds-o.org/> ds-o.org" by April 1, 2017. The workshop programme will be announced soon after the deadline. Please note that if you are already planning to attend CEC 2017 or CPAIOR 2017 and have an accepted contribution, you could present the same work. All submissions will be checked for suitability and there is a limited number of presentation slots. In order to join the workshop just to follow the presentations, please register your interest simply by sending an email to "info [ATT] <http://ds-o.org/> ds-o.org". If you know a colleague who might be interested in participating this workshop please feel free to forward this invitation. Attendance is free of charge. If you have any questions, then please do not hesitate to contact us. We look forward to seeing you at the workshop.
