Matryoshka Query Transformer for Large Vision-Language Models

NeurIPS 2024poster

Large Vision-Language Models (LVLMs) typically encode an image into a fixed number of visual tokens (e.g., 576) and process these tokens with a language model. Despite their strong performance, LVLMs face challenges in adapting to varying computational constraints. This raises the question: can we a…

Text encoders bottleneck compositionality in contrastive vision-language models

EMNLP 2023long main

Performant vision-language (VL) models like CLIP represent captions using a single vector. How much information about language is lost in this bottleneck? We first curate CompPrompts, a set of increasingly compositional image captions that VL models should be able to capture (e.g., single object, to…

What's "up" with vision-language models? Investigating their struggle with spatial reasoning

EMNLP 2023long main

Recent vision-language (VL) models are powerful, but can they reliably distinguish "right" from "left"? We curate three new corpora to quantify model comprehension of such basic spatial relations. These tests isolate spatial reasoning more precisely than existing datasets like VQAv2, e.g., our What'…

Towards General Purpose Vision Systems: An End-to-End Task-Agnostic Vision-Language Architecture

CVPR 2022oral

Computer vision systems today are primarily N-purpose systems, designed and trained for a predefined set of tasks. Adapting such systems to new tasks is challenging and often requires non-trivial modifications to the network architecture (e.g. adding new output heads) or training process (e.g. addin…

Webly Supervised Concept Expansion for General Purpose Vision Models

ECCV 2022poster

"General purpose vision (GPV) systems are models that are designed to solve a wide array of visual tasks without requiring architectural changes. Today, GPVs primarily learn both skills and concepts from large fully supervised datasets. Scaling GPVs to tens of thousands of concepts by acquiring data…
