ViQ: Text-Aligned Visual Quantized Representations at Any Resolution

2026-06-25 · Source: Computer Vision and Pattern Recognition · Field: Technology & Digital — Artificial Intelligence & Machine Learning · Depth: Expert, quick

Summary

ViQ is a Visual Quantized Representations framework designed to create a unified, discrete representation for text and vision, addressing the challenge of balancing low-level details and high-level semantics. Unlike existing methods that often sacrifice one for the other, ViQ supports arbitrary visual inputs at native resolutions. Its two-stage quantization learning process involves text-aligned pre-training, which enhances the visual encoder with semantic supervision from a pretrained language model, and feature discretization, employing a proximal representation learning strategy and a position-aware head-wise quantization mechanism. Experiments show ViQ achieves competitive performance against state-of-the-art continuous vision encoders, maintains high precision in low-level reconstruction, and accelerates multimodal training by 20%-70% with various base LLMs.

Key takeaway

For Machine Learning Engineers building multimodal systems, ViQ offers a compelling solution to the trade-off between semantic depth and visual detail in discrete representations. You should consider integrating ViQ to process native-resolution visual inputs, potentially accelerating your multimodal training by 20%-70% with existing LLMs. This framework enables more efficient and unified modeling, simplifying your development workflow.

Key insights

ViQ balances semantic richness and detail preservation in discrete visual representations for efficient, unified multimodal modeling.

Principles

• Unified text-vision representation simplifies multimodal modeling.
• Balancing semantics and details is crucial for discrete visual reps.
