Robust Hyperbolic Learning with Curvature-Aware Optimization

NeurIPS 2025poster

Hyperbolic deep learning has become a growing research direction in computer vision due to the unique properties afforded by the alternate embedding space. The negative curvature and exponentially growing distance metric provide a natural framework for capturing hierarchical relationships between da…

A Cross-Domain Benchmark for Active Learning

NeurIPS 2024poster

Active Learning (AL) deals with identifying the most informative samples for labeling to reduce data annotation costs for supervised learning tasks. AL research suffers from the fact that lifts from literature generalize poorly and that only a small number of repetitions of experiments are conducted…

GraFITi: Graphs for Forecasting Irregularly Sampled Time Series

AAAI 2024technical

Forecasting irregularly sampled time series with missing values is a crucial task for numerous real-world applications such as healthcare, astronomy, and climate sciences. State-of-the-art approaches to this problem rely on Ordinary Differential Equations (ODEs) which are known to be slow and often…
