NOH-NMS: Improving Pedestrian Detection by Nearby Objects Hallucination

1 code implementation27 Jul 2020 Penghao Zhou, Chong Zhou, Pai Peng, Junlong Du, Xing Sun, Xiaowei Guo, Feiyue Huang

Greedy-NMS inherently raises a dilemma, where a lower NMS threshold will potentially lead to a lower recall rate and a higher threshold introduces more false positives.

Anomaly Detection via Graphical Lasso

1 code implementation10 Nov 2018 Haitao Liu, Randy C. Paffenroth, Jian Zou, Chong Zhou

Accordingly, we propose a novel optimization problem that is similar in spirit to Robust Principal Component Analysis (RPCA) and splits the sample covariance matrix $M$ into two parts, $M=F+S$, where $F$ is the cleaned sample covariance whose inverse is sparse and computable by Graphical Lasso, and $S$ contains the outliers in $M$.

Generative Adversarial Active Learning for Unsupervised Outlier Detection

2 code implementations28 Sep 2018 Yezheng Liu, Zhe Li, Chong Zhou, Yuanchun Jiang, Jianshan Sun, Meng Wang, Xiangnan He

In this paper, we approach outlier detection as a binary-classification issue by sampling potential outliers from a uniform reference distribution.
