About

More about me →

I'm an AI infrastructure and speech-language systems architect with ~10 years building production AI. Previously a core AI architect of Alibaba's Tmall Genie, where I designed the NLU domain-classification engine and end-to-end ASR architecture. Primary author of standalone TensorBoard, first inventor on two granted patents, and a former Apache MXNet PMC member.

Selected work

Standalone TensorBoard

Primary author of dmlc/tensorboard. Decoupled TensorBoard from TensorFlow so MXNet and PyTorch teams could inspect training without framework lock-in. Adopted by AWS as the basis for mxboard; referenced by PyTorch's tensorboardX.

Indicator Loss for Context-Aware ASR

First inventor on patent CN113808593B. Explicit, step-level supervised gating for personalized speech recognition — deployed on Tmall Genie at national scale, enabling real-time bias-list updates without weeks-long retraining.

Memory-Network NLU for Tmall Genie

First inventor on patent CN112002313B. Replaced brittle rule-template routing with a memory-network architecture fusing rules and learned representations, raising production domain-classification accuracy from ~65% to ~85%.
