关于About

我现在在创业，担任非雨（ThisRainIsNotARealRain）创始人/CEO。我们面向动漫内容生产的工业化升级，在RealRain上构建“可控、可编辑、可协作、可规模化”的 AIGC 多Agent 生产系统：将传统产线映射为可模拟/回放/调度的数字孪生产线，并用多模态资产管理与一致性控制沉淀长期内容资产。我的工程与研究经验来自计算机视觉/视觉语言与多模态、AI4Science 与 Physics ML，擅长把研究原型推进为可复现、可交付的系统。 I’m currently building ThisRainIsNotARealRain as Founder/CEO. With RealRain, we’re upgrading animation production via a controllable, editable, collaborative, and scalable AIGC multi-agent system: a digital-twin pipeline with simulation/replay/scheduling, plus multimodal asset management and consistency control for long-term content assets. My background spans computer vision/vision-language and multimodal learning, AI4Science, and physics ML—bridging research prototypes into reproducible, shippable systems.
