2/ difFOCI is a plug-and-play differentiable relaxation of the Chatterjee's correlation coefficient, a popular, recently-proposed rank-based estimator. We show that difFOCI improves on numerous ML and AI applications, including domain shift, spurious correlations and fairness

1/ Happy to share my first accepted paper as a PhD student at Meta and ENS, Paris which I will present at @iclr-conf.bsky.social: 📚 Our work proposes difFOCI, a novel rank-based objective for ✨better feature learning✨ In collab with David Lopez-Paz, @giuliobiroli.bsky.social and Levent Sagun!
