SparseDM: Toward Sparse Efficient Diffusion Models

no code implementations16 Apr 2024 Kafeng Wang, Jianfei Chen, He Li, Zhenpeng Mi, Jun Zhu

Diffusion models have been extensively used in data generation tasks and are recognized as one of the best generative models.

Toward Efficient Automated Feature Engineering

no code implementations26 Dec 2022 Kafeng Wang, Pengyang Wang, Chengzhong Xu

Specifically, we construct the AFE pipeline based on reinforcement learning setting, where each feature is assigned an agent to perform feature transformation \com{and} selection, and the evaluation score of the produced features in downstream tasks serve as the reward to update the policy.

SenseMag: Enabling Low-Cost Traffic Monitoring using Non-invasive Magnetic Sensing

no code implementations24 Oct 2021 Kafeng Wang, Haoyi Xiong, Jie Zhang, Hongyang Chen, Dejing Dou, Cheng-Zhong Xu

Extensive experiment based on real-word field deployment (on the highways in Shenzhen, China) shows that SenseMag significantly outperforms the existing methods in both classification accuracy and the granularity of vehicle types (i. e., 7 types by SenseMag versus 4 types by the existing work in comparisons).
