Introduction

Maximizing Multi-modal Mutual Information Pre-training (M3I Pre-training), initially described in arxiv, is a simple yet effective one-stage pre-training paradigm. It can integrate existing pre-training methods (supervised pre-training, weakly-supervised pre-training and self-supervised pre-training) under an unified mutual information perspective and maintain all desired properties through a single-stage pre-training. Notably, we successfully pre-train a 1B model (InternImage-H) with M3I Pre-training and achieve new record 65.4 mAP on COCO detection test-dev, 62.5 mAP on LVIS detection minival, and 62.9 mIoU on ADE20k.
