Prior land surface reflectance-based sandstorm detection from space using deep learning

no code implementations Frontiers in Earth Science 2022 Yu Qu, Lin Sun, Qing hua Su, Nan Ma, Zhi hui Wang, Xi rong Liu

Based on the dataset, the difference between the reflectance observed by the satellite and the corresponding LSR is generated, which is used as a characteristic parameter of sandstorm detection with the deep learning method.

Weakly Supervised Learning Meets Ride-Sharing User Experience Enhancement

no code implementations19 Jan 2020 Lan-Zhe Guo, Feng Kuang, Zhang-Xun Liu, Yu-Feng Li, Nan Ma, Xiao-Hu Qie

For example, in user experience enhancement from Didi, one of the largest online ride-sharing platforms, the ride comment data contains severe label noise (due to the subjective factors of passengers) and severe label distribution bias (due to the sampling bias).
