Third workshop on COmbining COnstraint solving with MIning and LEarning

Co-located with ECAI 2014 in Prague, Czech Republic


The field of constraint solving has traditionally evolved quite independently from those of machine learning and data mining. In recent years, interest has been growing on the connections between these fields, and the potential advantages of their integration. Integration can work in two ways, on the one hand, various types of constraint solvers can be included in machine learning and data mining algorithms, for example to provide a uniform and effective way to characterize the desired solutions; on the other hand, machine learning can help in addressing constraint satisfaction problems, both at the level of search, by improving search or integrating intelligent meta-heuristics, as well as at the level of modelling, for example by learning constraints or interactively supporting a decision maker.

While promising initial results have been achieved in such directions, many options are unexplored and further research is needed in order to establish a systematic approach to this integration. The best way to reach the full potential of such integrations is in a multi-disciplinary way.


The main purpose of this workshop is to provide an open environment where researchers in machine learning, data mining and constraint solving can exchange ideas and discuss promising approaches, crucial issues, open problems and interesting formalizations of new tasks. To encourage this, we will allow three different types of submissions:

  • original contributions (unpublished work)
  • relevant contributions recently submitted or published elsewhere (only oral)
  • vision statements, works in progress and short overviews

The following is a non-exclusive list of topics of interest:

  • data mining/machine learning using constraint solving techniques
  • learning with constraints
  • constraint-based languages for data mining/machine learning
  • preference learning for constraint solving
  • automated constraint modeling and solving
  • constraint acquisition
  • interactive constraint solving
  • solver portfolio optimisation
  • machine learning in search
  • integrating learning and search
  • automated parameter optimization / algorithm configuration

In addition to the received contributions, the workshop will include invited talks from prominent researchers working in the intersection between constraint technology, machine learning and data mining. The workshop is planned to end with a broad discussion on the most relevant open problems and research directions.

The announcement of this event was sent to KDD Nuggets: Analytics, Big Data, Data Mining, & Data Science Resources.
