- STEM foundation models, multi-modal models for STEM
- Physics of AI

My research focused on using AI and optimization algorithms for data-driven modeling, simulation, optimization, and control. The outcomes have been widely deployed across Huawei business units, including ICT, CBG, HiSilicon, Computing, Car, etc.
From an application perspective, our research targets can be broadly categorized into two types:
- Complex industrial systems: sensing, modeling, parameter optimization, and optimal control for cellular networks, data center networks, optical communication and sensing, home environments, computing clusters, power grids, etc. These systems often lack mechanistic models, or mechanistic models are only qualitatively accurate. We typically model them with strongly data-driven approaches embedded with domain expertise.
- Simple physical systems: surrogate simulation and inverse design in domains such as antennas, structures, materials, and circuits. Mechanistic models align well with real systems. We can use the language of numerical computation to integrate mechanistic and data-driven models.
From a research perspective, we proposed the first learning-based end-to-end PDE mesh movement optimization method, and designed the first end-to-end differentiable quantum transport simulator capable of handling semiconductor device optimization problems with tens of thousands of degrees of freedom. My overall understanding of Deep Learning for Science (marked red are our works):

主要研究如何利用人工智能与优化算法进行数据驱动的建模、仿真、优化与控制,相关成果已在华为通信、终端、芯片、计算、车等业务场景广泛落地。
从应用角度,我们的研究对象大致可以分为两类:
- 复杂工业系统:蜂窝网络、数据中心网络、光通信光传感、家庭环境、计算集群、电网等系统的感知、建模、参数优化与最优控制。没有机理模型或机理模型仅定性准确。通常使用强数据驱动+专家先验嵌入的方式建模。
- 简单物理系统:天线、结构、材料、电路等领域的代理仿真与逆向设计。机理模型和实际系统对应良好。可以使用数值计算的语言,深度融合机理和数据驱动模型。
从研究角度,我们提出了首个基于学习的端到端的PDE网格移动优化方法;设计了首个端到端可微分的量子输运仿真器,可处理上万自由度的半导体器件优化问题。我对 Deep Learning for Science 的整体理解(标红为我们的工作):
