Hierarchical Spatio-Temporal Transformer for Coherent Emergency Department Forecasting
Filipa Lino, Bárbara Tavares, Carlos Santiago +2
The paper introduces HierSTT, a hierarchical Transformer framework that jointly forecasts emergency department demand at hospital, regional, and national levels while enforcing cro…
Native Hierarchical and Compositional Representations with Subspace Embeddings
Gabriel Moreira, Zita Marinho, Manuel Marques +2
Traditional embeddings represent datapoints as vectors, which makes similarity easy to compute but limits how well they capture hierarchies and compositionality. We propose a funda…
Spectral Guidance for Flexible and Efficient Control of Diffusion Models
Gabriel Moreira, Manuel Marques, João Paulo Costeira +1
We introduce Spectral Guidance, a framework for controlling diffusion models by leveraging the intrinsic geometry of the generative process. As data is progressively corrupted by n…
