Sharpness-diversity tradeoff: improving flat ensembles with SharpBalance

Neural Information Processing Systems

Building on this, our study investigates the interplay between sharpness and diversity within deep ensembles, illustrating their crucial role in robust generalization to both in-distribution (ID) and out-of-distribution (OOD) data.




Introducing Spectral Attention for Long-Range Dependency in Time Series Forecasting

Neural Information Processing Systems

Spectral Attention preserves long-period trends through a low-pass filter and facilitates gradient to flow between samples. Spectral Attention can be seamlessly integrated into most sequence models, allowing models with fixed-sized look-back windows to capture long-range dependencies over thousands of steps.





KG-FIT: Knowledge Graph Fine-Tuning Upon Open-World Knowledge

Neural Information Processing Systems

While current KGE methods have shown success, many are limited to the graph structure alone, neglecting the wealth of open-world knowledge surrounding entities not explicitly depicted in the KG, which is manually created in most cases.
