Molmo2: Open Weights and Data for Vision-Language Models with Video Understanding and Grounding

CVPR 2026

Today's strongest video-language models (VLMs) remain proprietary, and the strongest open-weight models often rely on synthetic data from proprietary VLMs and do not disclose their training data or recipe. As a result, the open-source community lacks the foundations needed to improve on the state-of

SAGE: Training Smart Any-Horizon Agents for Long Video Reasoning with Reinforcement Learning

CVPR 2026

As humans, we are natural any-horizon reasoners, i.e., we can decide whether to iteratively skim long videos or watch short ones in full when necessary for a given task. With this in mind, one would expect video reasoning models to reason flexibly across different durations. However, SOTA models are

ReSpec: Relevance and Specificity Grounded Online Filtering for Learning on Video-Text Data Streams

CVPR 2025poster

The rapid growth of video-text data presents challenges in storage and computation during training. Online learning, which processes streaming data in real-time, offers a promising solution to these issues while also allowing swift adaptations in scenarios demanding real-time responsiveness. One str…

Sample Selection via Contrastive Fragmentation for Noisy Label Regression

NeurIPS 2024poster

As with many other problems, real-world regression is plagued by the presence of noisy labels, an inevitable issue that demands our attention. Fortunately, much real-world data often exhibits an intrinsic property of continuously ordered correlations between labels and features, where data points w…

Continual Learning on Noisy Data Streams via Self-Purified Replay

ICCV 2021poster

Continually learning in the real world must overcome many challenges, among which noisy labels are a common and inevitable issue. In this work, we present a replay-based continual learning framework that simultaneously addresses both catastrophic forgetting and noisy labels for the first time. Our s…

Imbalanced Continual Learning with Partitioning Reservoir Sampling

ECCV 2020poster

Continual learning from a sequential stream of data is a crucial challenge for machine learning research. Most studies have been conducted on this topic under the single-label classification setting along with an assumption of balanced label distribution. This work expands this research horizon towar…
