Training Process - The training of Emu3 consists of three stages: 1. Pre-training with large-scale multimodal data, balancing the loss weights of text and visual tokens to prevent dominance of visual tokens [10]. 2. Post-training for quality fine-tuning on generation tasks, incorporating human preference optimization [10]. 3. Inference supporting classifier-free guidance for low-latency and high-throughput generation [11].
