Core Viewpoint - The article discusses the advancements in embodied intelligence, particularly focusing on diffusion strategies and the introduction of a new method called Cocos, which addresses the issue of loss collapse in training diffusion policies, leading to improved training efficiency and performance [3][11][25]. Summary by Sections Introduction - Embodied intelligence is a cutting-edge field in AI research, emphasizing the need for robots to understand and execute complex tasks effectively. Diffusion policies have emerged as a mainstream paradigm for constructing visual-language-action (VLA) models, although training efficiency remains a challenge [3]. Loss Collapse and Cocos - The article identifies loss collapse as a significant challenge in training diffusion strategies, where the neural network struggles to distinguish between generation conditions, leading to degraded training objectives. Cocos modifies the source distribution to depend on generation conditions, effectively addressing this issue [6][9][25]. Flow Matching Method - Flow matching is a core method in diffusion models, transforming a simple source distribution into a complex target distribution through optimization. The article outlines the optimization objectives for conditional distribution flow matching, which is crucial for VLA models [5][6]. Experimental Results - The article presents quantitative experimental results demonstrating that Cocos significantly enhances training efficiency and strategy performance across various benchmarks, including LIBERO and MetaWorld, as well as real-world robotic tasks [14][16][19][24]. Case Studies - Case studies illustrate the practical applications of Cocos in simulation tasks, highlighting its effectiveness in improving the robot's ability to distinguish between different camera perspectives and successfully complete tasks [18][21]. Source Distribution Design - The article discusses experiments on source distribution design, comparing different standard deviations and training methods. It concludes that a standard deviation of 0.2 is optimal, and using VAE for training the source distribution yields comparable results [22][24]. Conclusion - Cocos provides a general improvement for diffusion strategy training by effectively solving the loss collapse problem, thereby laying a foundation for future research and applications in embodied intelligence [25].
