An Online Algorithm for Chance Constrained Resource Allocation

no code implementations6 Mar 2023 Yuwei Chen, Zengde Deng, Yinzhi Zhou, Zaiyi Chen, Yujie Chen, Haoyuan Hu

This paper studies the online stochastic resource allocation problem (RAP) with chance constraints.

Range Resolution Enhanced Method with Spectral Properties for Hyperspectral Lidar

no code implementations3 Mar 2023 Yuhao Xia, Shilong Xu, Hui Shao, Ahui Hou, Jiajie Fang, Fei Han, Youlong Chen, Jiaqi Wen, Yuwei Chen, Yihua Hu

We use one single skew-normal distribution (SND) model to fit waveforms of all spectral channels first and count the geometric center position distribution of the echoes to decide whether it contains multi-targets.

T-SNE Is Not Optimized to Reveal Clusters in Data

no code implementations6 Oct 2021 Zhirong Yang, Yuwei Chen, Jukka Corander

Second, we check the assumptions in the clustering guarantee of t-SNE and find they are often violated for real-world data sets.
