Analyze the Robustness of Classifiers under Label Noise

no code implementations12 Dec 2023 Cheng Zeng, YiXuan Xu, Jiaqi Tian

This study explores the robustness of label noise classifiers, aiming to enhance model resilience against noisy data in complex real-world scenarios.

Analyze the robustness of three NMF algorithms (Robust NMF with L1 norm, L2-1 norm NMF, L2 NMF)

no code implementations3 Dec 2023 Cheng Zeng, Jiaqi Tian, YiXuan Xu

Non-negative matrix factorization (NMF) and its variants have been widely employed in clustering and classification tasks (Long, & Jian , 2021).

AOP-Net: All-in-One Perception Network for Joint LiDAR-based 3D Object Detection and Panoptic Segmentation

no code implementations2 Feb 2023 YiXuan Xu, Hamidreza Fazlali, Yuan Ren, Bingbing Liu

In this method, a dual-task 3D backbone is developed to extract both panoptic- and detection-level features from the input LiDAR point cloud.

A Versatile Multi-View Framework for LiDAR-based 3D Object Detection with Guidance from Panoptic Segmentation

no code implementations CVPR 2022 Hamidreza Fazlali, YiXuan Xu, Yuan Ren, Bingbing Liu

In our method, the 3D object detection backbone in Bird's-Eye-View (BEV) plane is augmented by the injection of Range-View (RV) feature maps from the 3D panoptic segmentation backbone.

SMAC-Seg: LiDAR Panoptic Segmentation via Sparse Multi-directional Attention Clustering

no code implementations31 Aug 2021 Enxu Li, Ryan Razani, YiXuan Xu, Liu Bingbing

Thus, we propose to use a novel centroid-aware repel loss as an additional term to effectively supervise the network to differentiate each object cluster with its neighbours.
