== MultiMediate: Multi-modal Behaviour Analysis for Artificial Mediation ==

== https://multimediate-challenge.org/ ==

== Challenge Description ==

Estimating the momentary level of engagement from multi-modal
participant behaviour is an important prerequisite for assistive
systems that support human interactions. At the same time, the
connection between engagement and behaviour heavily depends on
situational and cultural characteristics. Therefore,
MultiMediate'25 poses the cross-cultural, multi-domain engagement
estimation challenge. The challenge covers a unique combination of
training and test data from diverse cultural backgrounds, including
Japanese, Chinese, German, Arabic, Indonesian, and French speakers, as
well as different interaction situations (group vs. dyadic). In
addition to evaluation metrics that quantify the overall quality of
predictions, MultiMediate'25 will also quantify the amount of bias
in predictions with respect to the variables gender and cultural
background. In addition to engagement estimation, we continue to
invite submissions to popular tasks from previous iterations of the
challenge: eye contact detection, bodily behaviour recognition,
backchannel detection.

== Datasets & Evaluation Protocol ==

Training datasets for all tasks are available from our website. We
additionally provide baseline implementations along with pre-computed
features to minimise the overhead for participants. Test sets will be
released two weeks before the challenge deadline. Participants will in
turn submit their predictions for evaluation against ground truth on
our servers. For previous years' tasks, the test sets are already
published and three evaluations on the test set can be performed per
month.
