A Pilot Study of Relating MYCN-Gene Amplification with Neuroblastoma-Patient CT Scans

no code implementations21 May 2022 Zihan Zhang, Xiang Xiang, Xuehua Peng, Jianbo Shao

Neuroblastoma is one of the most common cancers in infants, and the initial diagnosis of this disease is difficult.

Lightweight Human Pose Estimation Using Heatmap-Weighting Loss

no code implementations21 May 2022 Shiqi Li, Xiang Xiang

Recent research on human pose estimation exploits complex structures to improve performance on benchmark datasets, ignoring the resource overhead and inference speed when the model is actually deployed.

Coarse-To-Fine Incremental Few-Shot Learning

1 code implementation24 Nov 2021 Xiang Xiang, Yuwen Tan, Qian Wan, Jing Ma

Such images form a new training set (i. e., support set) so that the incremental model is hoped to recognize a basenji (i. e., query) as a basenji next time.

Entropy-based Optimization via A* Algorithm for Parking Space Recommendation

no code implementations19 Apr 2021 Xin Wei, Runqi Qiu, Houyu Yu, Yurun Yang, Haoyu Tian, Xiang Xiang

This paper addresses the path planning problems for recommending parking spaces, given the difficulties of identifying the most optimal route to vacant parking spaces and the shortest time to leave the parking space.

NormFace: L2 Hypersphere Embedding for Face Verification

3 code implementations21 Apr 2017 Feng Wang, Xiang Xiang, Jian Cheng, Alan L. Yuille

We show that both strategies, and small variants, consistently improve performance by between 0. 2% to 0. 4% on the LFW dataset based on two models.
