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…

Learning Visual-Semantic Subspace Representations

Gabriel Moreira, Manuel Marques, João Paulo Costeira +1

Learning image representations that capture rich semantic relationships remains a significant challenge. Existing approaches are either contrastive, lacking robust theoretical guar…
