The collaboration is building a large-compute-scale AI platform for the hosting of large scientific datasets, models, and machine learning competitions to drive forward discoveries in high energy physics and cosmology. The initial focus is on discovering and minimizing systematic uncertainties in High Energy Physics through a sequence of challenges that will bring together researchers across physics and machine learning. ChaLearn sponsors a PhD student and a freelance engineer. The expenses this include the salary of the PhD student (via a donation made to Université Paris-Saclay), and prizes and travel awards given to challenge participants and organizers. 9969 X 65330 LAP PROGRAM: The Looking at People (LAP) challenge series in computer vision is organized in collaboration with Universitat Barcelona https://chalearnlap.cvc.uab.cat/. This year we sponsored the Face anti-spoofing, ICCV 2025 https://sites.google.com/view/face-anti-spoofing-challenge/welcome. We also supported the creation and annotations of a new dataset for diadic interactions (work in progress). 4515 X 5371 PAPER REVIEW: This is a program on automated reviews of scientific papers. This year we worked on a paper to help verify that camera-ready papers include corrections agreed upon between authors and reviewers (work in progress). We supported the internships of students. 0 5779 CODALAB COMPETITIONS: This program sponsors the development of competition platforms. This year, we rolled out the new benchmark platform codabench.org, in replacement for Codalab. Together Codalab and Codabench hold a strong position compared to Kaggle and Tianchi: https://mlcontests.com/state-of-competitive-machine-learning-2025. The code is open-sourced: https://github.com/codalab/codalab-competitions/issues. We are editing a book on challenges and benchmarks: https://sites.google.com/chalearn.org/book/home. We supported the editing work. 0 6166 82646 Kristin Bennett Treasurer, Director 1 0 0 0 Anne-Catherine Letournel Secretary, Director 0.5 0 0 0 Sergio Escalera Vice-president, Director 0.5 0 0 0 Isabelle Guyon President 2 0 0 0 Hugo-Jair Escalante Balderas Director 0.5 0 0 0 Antoine Marot Director 0.5 0 0 0 Magali Richard Director 0.5 0 0 0 David Rousseau Director 0.5 0 0 0 Sebastien Treguer Director 0.5 0 0 0 Evelyne Viegas Director 0.5 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 CA Isabelle Guyon 2443 Fillmore St / PMB 380-6329 San Francisco CA 941151814 5103292527 0 0 0 0 0 0 0 0 0 0 0 NONE NONE 1 X 13485 4980 189000 192000 180485 579950 0 0 0 0 0 0 0 0 13485 4980 189000 192000 180485 579950 76203 503747 0 0 0 0 0 0 0 0 0 0 0 0 579950 0 0.86860 0.88622 X RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED Form 990-EZ, Part I, Line 10 Prizes for the Anti-spoofing challenge (Looking at People -- LAP -- program): 4515 USD; Prizes for the Fair Universe challenge: 9969 USD Form 990-EZ, Part I, Line 16 We subsidized living and travel expenses of students, in the amount of 7828 USD; We reimbursed travel expenses to challenge organizers, in the amount of 4977 USD; We also paid 41 USD for a tax program and 10 USD in bank fees.
