[Wang Xingxing of Yushu Technology: The core challenge of physical AI lies in the alignment of the model with the physical world] On November 5th, at the 9th Hongqiao International Economic Forum, Wang Xingxing, founder and chairman of Yushu Technology, made an appearance at the "Humanoid Robots and Embodied Intelligent Industry Innovation and Development Cooperation" sub-forum. Talking about the core challenge of current physical AI, Wang Xingxing believes that it mainly lies in the alignment between the model and the physical world. In his opinion, the current understanding ability of the multi-modal model itself is already good. The biggest problem is the error in input and output alignment, including the deviation between the sensor measurement at the input level and the real state, and the deviation between the action instructions at the output level and the actual movement. Wang Xingxing judged that this part of the problem may be solved in the next 1-2 years. (Reporter Zhang Xiaoyu)
