Planning to Learn Workshop (PlanLearn)

Workshop paper submission deadline moved to July 7

For new dates see here!

Motivation and General Description

The task of constructing composite systems, that is systems composed of more than one part, can be seen as interdisciplinary area which builds on expertise in different domains. The aim of this workshop is to explore the possibilities of constructing such systems with the aid of Machine Learning and exploiting the know-how of Data Mining. One way of producing composite systems is by inducing the constituents and then by putting the individual parts together.
For instance, a text extraction system may be composed of various subsystems, some oriented towards tagging, morphosyntactic analysis or word sense disambiguation. This may be followed by selection of informative attributes and finally generation of the system for the extraction of the relevant information. Machine Learning techniques may be employed in various stages of this process.
The problem of constructing complex systems can thus be seen as a problem of planning to resolve multiple (possibly interacting) tasks. So, one important issue that needs to be addressed is how these multiple learning processes can be coordinated. Each task is resolved using certain ordering of operations. Meta-learning can be useful in this process. It can help us to retrieve previous solutions conceived in the past and re-use them in new settings.
The aim of the workshop is to explore the possibilities of this new area, offer a forum for exchanging ideas and experience concerning the state-of-the art, permit to bring in knowledge gathered in different but related and relevant areas and outline new directions for research.

Lines of research covered by the workshop - Topics of Interest

Of particular interest are methods and proposals that address the following issues:

  • Planning to construct composite systems,
  • Exploitation of ontologies of tasks and methods,
  • Representation of learning goals and states in learning,
  • Control and coordination of learning processes,
  • Recovering / adapting sequences of DM operations,
  • Meta-learning and exploitation of meta-knowledge,
  • Layered learning,
  • Multi-task learning,
  • Transfer learning,
  • Multi-predicate learning (and other relevant ILP methods),
  • Combining induction and abduction,
  • Multi-strategy learning,
  • Learning to learn.

Other areas may be covered, provided they are relevant towards the overall aims of the workshop.
