Boosting Causal Discovery via Adaptive Sample Reweighting

ICLR 2023poster

Under stringent model type and variable distribution assumptions, score-based causal discovery methods learn the directed acyclic graph (DAG) from observational data by evaluating candidate graphs over an averaged score function. Despite the great success in low-dimensional linear systems, it has be…

Empowering Collaborative Filtering with Principled Adversarial Contrastive Loss

NeurIPS 2023poster

Contrastive Learning (CL) has achieved impressive performance in self-supervised learning tasks, showing superior generalization ability. Inspired by the success, adopting CL into collaborative filtering (CF) is prevailing in semi-supervised topK recommendations. The basic idea is to routinely condu…
