Unsupervised Abnormal Stop Detection for Long Distance Coaches with Low-Frequency GPS
Jiaxin Deng, Junbiao Pang, Jiayu Xu +1
In our urban life, long distance coaches supply a convenient yet economic approach to the transportation of the public. One notable problem is to discover the abnormal stop of the…
Modeling the Popularity of Events on Web by Sparsity and Mutual-Excitation Guided Graph Neural Network
Jiaxin Deng, Linlin Jia, Junbiao Pang +1
The content of a webpage described or posted an event in the cyberspace inevitably reflects viewpoints, values and trends of the physical society. Mapping an event on web to the po…
Bilateral Sharpness-Aware Minimization for Flatter Minima
Jiaxin Deng, Junbiao Pang, Baochang Zhang +1
Sharpness-Aware Minimization (SAM) enhances generalization by reducing a Max-Sharpness (MaxS). Despite the practical success, we empirically found that the MAxS behind SAM's genera…
Asymptotic Unbiased Sample Sampling to Speed Up Sharpness-Aware Minimization
Jiaxin Deng, Junbiao Pang, Baochang Zhang
Sharpness-Aware Minimization (SAM) has emerged as a promising approach for effectively reducing the generalization error. However, SAM incurs twice the computational cost compared…
Pixel-Wise Symbol Spotting via Progressive Points Location for Parsing CAD Images
Junbiao Pang, Zailin Dong, Jiaxin Deng +2
Parsing Computer-Aided Design (CAD) drawings is a fundamental step for CAD revision, semantic-based management, and the generation of 3D prototypes in both the architecture and eng…
Effective Gradient Sample Size via Variation Estimation for Accelerating Sharpness aware Minimization
Jiaxin Deng, Junbiao Pang, Baochang Zhang +1
Sharpness-aware Minimization (SAM) has been proposed recently to improve model generalization ability. However, SAM calculates the gradient twice in each optimization step, thereby…
