MUI-TARE: Multi-Agent Cooperative Exploration with Unknown Initial Position

no code implementations22 Sep 2022 Jingtian Yan, Xingqiao Lin, Zhongqiang Ren, Shiqi Zhao, Jieqiong Yu, Chao Cao, Peng Yin, Ji Zhang, Sebastian Scherer

To intelligently balance the robustness of sub-map merging and exploration efficiency, we develop a new approach for lidar-based multi-agent exploration, which can direct one agent to repeat another agent's trajectory in an \emph{adaptive} manner based on the quality indicator of the sub-map merging process.

SphereVLAD++: Attention-based and Signal-enhanced Viewpoint Invariant Descriptor

no code implementations6 Jul 2022 Shiqi Zhao, Peng Yin, Ge Yi, Sebastian Scherer

Our previous work provides a viewpoint-invariant descriptor to deal with viewpoint differences; however, the global descriptor suffers from a low signal-noise ratio in unsupervised clustering, reducing the distinguishable feature extraction ability.

An End-to-End Deep Learning Approach for Epileptic Seizure Prediction

no code implementations17 Aug 2021 Yankun Xu, Jie Yang, Shiqi Zhao, Hemmings Wu, Mohamad Sawan

Conventional seizure prediction works usually rely on features extracted from Electroencephalography (EEG) recordings and classification algorithms such as regression or support vector machine (SVM) to locate the short time before seizure onset.
