Connectionists: Call for Participation: ICCV'2021 Understanding Social Behavior in Dyadic and Small Group Interactions Challenge

Thu May 20 04:48:34 EDT 2021

Dear colleagues,

We cordially invite you to participate in our ICCV’2021 Understanding Social Behavior in Dyadic and Small Group Interactions Challenge - http://chalearnlap.cvc.uab.es/challenge/45/description/

Description: to advance and motivate the research on visual human behavior analysis in dyadic and small group interactions, this challenge will use a large scale, multimodal, and multiview (UDIVA<https://openaccess.thecvf.com/content/WACV2021W/HBU/papers/Palmero_Context-Aware_Personality_Inference_in_Dyadic_Scenarios_Introducing_the_UDIVA_Dataset_WACVW_2021_paper.pdf>) dataset recently collected by our group, which provides many related challenges. It will address two different problems, divided in two competition tracks:

  1.  Automatic self-reported personality recognition of single individuals (i.e., a target person) during a dyadic interaction, from two individual views.

  2.  Behavior forecasting: the focus of this track will be to estimate future (up to N frames) 2D facial landmarks, hand, and upper body pose of a target individual in a dyadic interaction.

In both tasks, multiview and multimodal information (audio-visual, transcriptions, context and medatada) are expected to be exploited to solve the problem.

Important Dates:

  *   Dataset access request period open: 18th May, 2021

  *   Start of the Challenge (development phase): June 1st, 2021

  *   Start of test phase: September 1st, 2021

  *   End of the Challenge: September 17th, 2021

  *   Release of final results: September 30th, 2021

Top winning solutions will be invited to give a talk to present their work at the associated ICCV 2021 ChaLearn workshop (http://chalearnlap.cvc.uab.es/workshop/44/description/). In addition to this, challenge participants, as well as the research community in the field and from related disciplines (e.g. affective computing, social signal processing and human-computer interaction), are invited to submit a paper to be published in Proceedings of Machine Learning Research (PMLR). In line with these, we accept papers addressing the issues related to, but not limited to, these topics:

  *   Challenge related papers, describing their methods and results;

  *   Detection, understanding, modeling and synthesis of individual and interpersonal social signals and dynamics;

  *   Verbal/nonverbal communication analysis in dyadic and small groups;

  *   Contextual analysis in dyadic and small groups;

  *   Datasets, annotation protocols, and bias discovering/mitigation in dyadic and small groups;

  *   Interpretability/explainability in dyadic and small groups;

Important Dates:

  *   Paper submission deadline (PMLR): October 31st, 2021

  *   Author notification: November 30th, 2021

  *   Camera-ready: December 20th, 2021

Prizes: Top winning solutions will be invited to give a talk to present their work at the associated ICCV 2021 ChaLearn workshop, will receive a winning certificate and will have free ICCV registration. Our sponsors are also offering the following prizes:

  *   Track 1: Top-1 solution: 1000$ / Top-2 solution: 500$ / Top-3 solution: 300$

  *   Track 2: Top-1 solution: 1000$ / Top-2 solution: 500$ / Top-3 solution: 300$

Honorable mention: based on the significance of the result in a particular trait/s (track 1) or body part (track 2) and the level of novelty/originality of the solution, in addition to top-3 solutions, we may announce additional honorable mentions, which will also receive a winning certificate and a free ICCV registration.

All the best,
