DataComp-VLM: Improved Open Datasets for Vision-Language Models

Matteo Farina, Vishaal Udandarao, Thao Nguyen +34

Building performant Vision-Language Models (VLMs) requires carefully curating large-scale training datasets, yet the community lacks systematic benchmarks for evaluating such curat…

MIRAGE: Protecting against Malicious Image Editing via False Moderation

Anshul Nasery, Ramnath Kumar, Cho-Jui Hsieh +1

The proliferation of AI-powered image editing systems raises serious concerns because it allows personal images to be arbitrarily manipulated at scale, with minimal effort, and a l…

Spurious Rewards: Rethinking Training Signals in RLVR

Rulin Shao, Shuyue Stella Li, Rui Xin +11

We show that reinforcement learning with verifiable rewards (RLVR) can elicit strong mathematical reasoning in certain language models even with spurious rewards that have little,…

Privasis: Synthesizing the Largest "Public" Private Dataset from Scratch

Hyunwoo Kim, Niloofar Mireshghallah, Michael Duan +11

Research involving privacy-sensitive data has always been constrained by data scarcity, standing in sharp contrast to other areas that have benefited from data scaling. This challe…

Concept-Aware Batch Sampling Improves Language-Image Pretraining

Adhiraj Ghosh, Vishaal Udandarao, Thao Nguyen +7

What data should a vision-language model be trained on? To answer this question, many data curation efforts center on the quality of a dataset. However, most of these existing meth…
