Overview of the ImageCLEF 2014 Domain Adaptation Task

This paper describes the first edition of the Domain Adaptation Task at ImageCLEF 2014. Domain adaptation refers to the challenge of leveraging over knowledge acquired when learning to recognize given classes on a database, when using a different data collection. We describe the scientific motivations behind the task, the research challenge on which the 2014 edition focused, the data and evaluation metric and results obtained by participants. After a discussion on the lesson learned during this first edition, we conclude with possible ideas for future editions of the task.
