Think Then Embed: Generative Context Improves Multimodal Embedding

ICLR 2026poster

There is a growing interest in Universal Multimodal Embeddings (UME), where models are required to generate task-specific representations. While recent studies show that Multimodal Large Language Models (MLLMs) perform well on such tasks, they treat MLLMs solely as encoders, overlooking their genera…

Continual Learning for Personalized Co-speech Gesture Generation

ICCV 2023poster

Co-speech gestures are a key channel of human communication, making them important for personalized chat agents to generate. In the past, gesture generation models assumed that data for each speaker is available all at once, and in large amounts. However in practical scenarios, speaker data comes se…

Low-Resource Adaptation for Personalized Co-Speech Gesture Generation

CVPR 2022poster

Personalizing an avatar for co-speech gesture generation from spoken language requires learning the idiosyncrasies of a person's gesture style from a small amount of data. Previous methods in gesture generation require large amounts of data for each speaker, which is often infeasible. We propose an…

Style Transfer for Co-Speech Gesture Animation: A Multi-Speaker Conditional-Mixture Approach

ECCV 2020poster

How can we teach robots or virtual assistants to gesture naturally? Can we go further and adapt the gesturing style to follow a specific speaker? Gestures that are naturally timed with corresponding speech during human communication are called co-speech gestures. A key challenge, called gesture styl…
