Anomaly Heterogeneity Learning for Open-set Supervised Anomaly Detection

1 code implementation19 Oct 2023 Jiawen Zhu, Choubo Ding, Yu Tian, Guansong Pang

Open-set supervised anomaly detection (OSAD) - a recently emerging anomaly detection area - aims at utilizing a few samples of anomaly classes seen during training to detect unseen anomalies (i. e., samples from open-set anomaly classes), while effectively identifying the seen anomalies.

DCPT: Darkness Clue-Prompted Tracking in Nighttime UAVs

1 code implementation19 Sep 2023 Jiawen Zhu, Huayi Tang, Zhi-Qi Cheng, Jun-Yan He, Bin Luo, Shihao Qiu, Shengming Li, Huchuan Lu

To address this, we propose a novel architecture called Darkness Clue-Prompted Tracking (DCPT) that achieves robust UAV tracking at night by efficiently learning to generate darkness clue prompts.

A Causal Inference Framework for Leveraging External Controls in Hybrid Trials

no code implementations15 May 2023 Michael Valancius, Herb Pang, Jiawen Zhu, Stephen R Cole, Michele Jonsson Funk, Michael R Kosorok

We consider the challenges associated with causal inference in settings where data from a randomized trial is augmented with control data from an external source to improve efficiency in estimating the average treatment effect (ATE).

Anomaly Detection under Distribution Shift

1 code implementation ICCV 2023 Tri Cao, Jiawen Zhu, Guansong Pang

Anomaly detection (AD) is a crucial machine learning task that aims to learn patterns from a set of normal training samples to identify abnormal samples in test data.

Visual Prompt Multi-Modal Tracking

1 code implementation CVPR 2023 Jiawen Zhu, Simiao Lai, Xin Chen, Dong Wang, Huchuan Lu

To inherit the powerful representations of the foundation model, a natural modus operandi for multi-modal tracking is full fine-tuning on the RGB-based parameters.

SRRT: Search Region Regulation Tracking

no code implementations10 Jul 2022 Jiawen Zhu, Xin Chen, Pengyu Zhang, Xinying Wang, Dong Wang, Wenda Zhao, Huchuan Lu

Trackers tend to lose the target object due to the limited search region or be interfered with by distractors due to the excessive search region.

High-Performance Transformer Tracking

1 code implementation25 Mar 2022 Xin Chen, Bin Yan, Jiawen Zhu, Huchuan Lu, Xiang Ruan, Dong Wang

First, we present a transformer tracking (named TransT) method based on the Siamese-like feature extraction backbone, the designed attention-based fusion mechanism, and the classification and regression head.
