Recent Projects

Actually, model compression is a kind of technique for developing portable deep neural networks with lower memory and computation costs. I have done several projects in Huawei including some smartphones' applications in 2019 and 2020 (e.g. Mate 30 and Honor V30). Currently, I am leading the AdderNet project, which aims to develop a series of deep learning models using only additions (Discussions on Reddit).

GhostNet on MindSpore: SOTA Lightweight CV Networks

Huawei Connect (HC) 2020 | MindSpore Hub

The initial verison of GhostNet was accepted by CVPR 2020, which achieved SOTA performance on ImageNet: 75.7% top1 acc with only 226M FLOPS. In the current version, we release a series computer vision models (e.g. int8 quantization, detection, and larger networks) on MindsSpore 1.0 and Mate 30 Pro (Kirin 990).

AI on Ascend: Real-Time Video Style Transfer

  

Huawei Developer Conference (HDC) 2020 | Online Demo

This project aims to develop a video style transfer system on the Huawei Atlas 200 DK AI developer Kit. The latency of the original model for processing one image is about 630ms. After accelerating it using our method, the lantency now is about 40ms.

Research

I'm interested in devleoping efficient models for computer vision (e.g. classification, detection, and super-resolution) using pruning, quantization, distilaltion, NAS, etc.
