Cheap-fake Detection with LLM using Prompt Engineering

no code implementations5 Jun 2023 Guangyang Wu, Weijie Wu, Xiaohong Liu, Kele Xu, Tianjiao Wan, Wenyi Wang

We enhance the baseline algorithm by incorporating a Large Language Model (LLM), GPT3. 5, as a feature extractor.

IDMS: Instance Depth for Multi-scale Monocular 3D Object Detection

no code implementations3 Dec 2022 Chao Hu, Liqiang Zhu, Weibing Qiu, Weijie Wu

Firstly, to enhance the model's processing ability for different scale targets, a multi-scale perception module based on dilated convolution is designed, and the depth features containing multi-scale information are re-refined from both spatial and channel directions considering the inconsistency between feature maps of different scales.

Spatio-Temporal-based Context Fusion for Video Anomaly Detection

no code implementations18 Oct 2022 Chao Hu, Weibin Qiu, Weijie Wu, Liqiang Zhu

Motion features are used multiple targets in the video frame to construct spatial context simultaneously, re-encoding the target appearance and motion features, and finally reconstructing the above features through the spatio-temporal dual-stream network, and using the reconstruction error to represent the abnormal score.

Normal Learning in Videos with Attention Prototype Network

1 code implementation25 Aug 2021 Chao Hu, Fan Wu, Weijie Wu, Weibin Qiu, Shengxin Lai

With models trained on the normal data, the reconstruction errors of anomalous scenes are usually much larger than those of normal ones.

Quadratic Optimization with Orthogonality Constraints: Explicit Lojasiewicz Exponent and Linear Convergence of Line-Search Methods

no code implementations5 Oct 2015 Huikang Liu, Weijie Wu, Anthony Man-Cho So

To determine the convergence rate of these methods, we give an explicit estimate of the exponent in a Lojasiewicz inequality for the (non-convex) set of critical points of the aforementioned class of problems.
