ViTok-v2: Scaling Native-Resolution Autoencoders to 5B

ICML 2026poster

Vision Transformer (ViT) tokenizers offer a scal- able alternative to convolutional auto-encoders, yet current architectures have two key limitations: their performance degrades when images vary in aspect ratio or resolution, and their reliance on adversarial losses makes them harder to train at sca…

Apollo: An Exploration of Video Understanding in Large Multimodal Models

CVPR 2025poster

Despite the rapid integration of video perception capabilities into Large Multimodal Models (LMMs), what drives their video perception remains poorly understood. Consequently, many design decisions in this domain are made without proper justification or analysis. The high computational cost of train…

Learnings from Scaling Visual Tokenizers for Reconstruction and Generation

ICML 2025poster

Visual tokenization via auto-encoding empowers state-of-the-art image and video generative models by compressing pixels into a latent space. However, questions remain about how auto-encoder design impacts reconstruction and downstream generative performance. This work explores scaling in auto-encode…

Video-STaR: Self-Training Enables Video Instruction Tuning with Any Supervision

ICLR 2025poster

The performance and reasoning capabilities of Large Multi-modal Models (LMMs) is dependent on the size and quality of their training datasets. However, collecting datasets that support chain-of-thought instruction tuning is highly challenging. Existing video instruction tuning datasets are often der…

VideoAgent: Long-form Video Understanding with Large Language Model as Agent

ECCV 2024poster

"Long-form video understanding represents a significant challenge within computer vision, demanding a model capable of reasoning over long multi-modal sequences. Motivated by the human cognitive process for long-form video understanding, we emphasize interactive reasoning and planning over the abili…

LOVM: Language-Only Vision Model Selection

NeurIPS 2023poster

Pre-trained multi-modal vision-language models (VLMs) are becoming increasingly popular due to their exceptional performance on downstream vision applications, particularly in the few- and zero-shot settings. However, selecting the best-performing VLM for some downstream applications is non-trivial,…
