Daniela Lopez de Luise 2nd CALL FOR PARTICIPATION:
REACT 2023 Challenge: Multiple Appropriate Facial Reaction Generation in Dyadic Interactions (REACT2023)
The first “Multiple Appropriate Facial Reaction Generation in Dyadic Interactions” challenge (REACT2023) to be held in conjunction with the ACM Multimedia (ACM-MM) 2023 in Ottawa, Canada, is calling for contributions in the form of papers and competition in the challenge. The competition will be using the NoXI, RECOLA, and UDIVA datasets which contain audio-video clip data of participants engaged in dyadic interactions. The challenge consists of two main tasks:
-
Task 1 – Offline Appropriate Facial Reaction Generation
-
Task 2 – Online Appropriate Facial Reaction Generation
Participants are invited to participate in one or both sub-challenges. For more information about the challenge, check our website https://sites.google.com/cam.ac.uk/react2023/home. To register and access the challenge data, please fill the registration form you will find on the website and feel free to contact us by email: reactmultimodalchallenge@gmail.com. For each task, training and validation data will be made available to participants. At the end of the competition, participants will be required to submit their trained models (in the form of working code) via the CodaLab platform. All submissions will be evaluated on a held-out test dataset to ensure a fair comparison. Participants will also be encouraged to submit a conference-style paper describing their proposed approach for tackling the challenge task(s) as well as the results obtained.
