=== Call for Papers ===

Adaptive reuse of learnt knowledge is of critical importance in the majority of knowledge-intensive application areas, particularly when the context in which the learnt model operates can be expected to vary from training to deployment. In machine learning this has been studied, for example, in relation to variations in class and cost skew in (binary) classification, leading to the development of tools such as ROC analysis to adjust decision thresholds to operating conditions concerning class and cost skew. More recently, considerable effort has been devoted to research on transfer learning, domain adaptation, and related approaches.

Given that the main business of predictive machine learning is to generalise from training to deployment, there is clearly scope for developing a general notion of operating context. Without such a notion, a model predicting sales in Prague for this week may perform poorly in Nancy for next Wednesday. The operating context has changed in terms of location as well as resolution. While a given predictive model may be sufficient and highly specialised for one particular operating context, it may not perform well in other contexts. If sufficient training data for the new context is available it might be feasible to retrain a new model; however, this is generally not a good use of resources, and one would expect it to be more cost-effective to learn one general, versatile model that effectively generalizes over multiple and possibly previously unseen contexts.

The aim of this workshop is to bring together people working in areas related to versatile models and model reuse over multiple contexts. Given the advances made in recent years on specific approaches such as transfer learning, an attempt to start developing an overarching theory is now feasible and timely, and can be expected to generate considerable interest from the machine learning community. Papers are solicited in all areas relating to model reuse and model generalization including the following areas:

* transfer learning
* data shift and concept drift
* domain adaptation
* transductive learning
* multi-task learning
* ROC analysis and cost-sensitive learning
* background knowledge
* relational learning
* context-aware applications
* incomplete information, abduction
* meta-learning

=== Submission of Papers ===

We welcome submissions describing work in progress as well as more mature work related to learning over multiple contexts. Submissions should be between 6 and 16 pages in the same format as the main conference (LNAI). Authors of accepted papers will be asked to prepare a poster, and selected authors will be given the opportunity of a plenary presentation during the workshop.

After the workshop, contributing authors will be invited to submit a paper to a special issue of the Machine Learning journal dedicated to the topic of the workshop.
