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…

BT^2: Backward-compatible Training with Basis Transformation

ICCV 2023poster

Modern retrieval system often requires recomputing the representation of every piece of data in the gallery when updating to a better representation model. This process is known as backfilling and can be especially costly in the real world where the gallery often contains billions of samples. Recent…

Spartan: Differentiable Sparsity via Regularized Transportation

NeurIPS 2022accept

We present Spartan, a method for training sparse neural network models with a predetermined level of sparsity. Spartan is based on a combination of two techniques: (1) soft top-k masking of low-magnitude parameters via a regularized optimal transportation problem and (2) dual averaging-based paramet…
