ConceptExpress: Harnessing Diffusion Models for Single-image Unsupervised Concept Extraction

ECCV 2024oral

"While personalized text-to-image generation has enabled the learning of a single concept from multiple images, a more practical yet challenging scenario involves learning multiple concepts within a single image. However, existing works tackling this scenario heavily rely on extensive human annotati…

PromptCCD: Learning Gaussian Mixture Prompt Pool for Continual Category Discovery

ECCV 2024poster

"We tackle the problem of Continual Category Discovery (CCD), which aims to automatically discover novel categories in a continuous stream of unlabeled data while mitigating the challenge of catastrophic forgetting – an open problem that persists even in conventional, fully supervised continual lear…

Token Compensator: Altering Inference Cost of Vision Transformer without Re-Tuning

ECCV 2024poster

"Token compression expedites the training and inference of Vision Transformers (ViTs) by reducing the number of the redundant tokens, , pruning inattentive tokens or merging similar tokens. However, when applied to downstream tasks, these approaches suffer from significant performance drop when the…
