UCTB: An Urban Computing Tool Box for Spatiotemporal Crowd Flow Prediction

1 code implementation7 Jun 2023 Liyue Chen, Di Chai, Leye Wang

To address these issues, we design and implement a spatiotemporal crowd flow prediction toolbox called UCTB (Urban Computing Tool Box), which integrates multiple spatiotemporal domain knowledge and state-of-the-art models simultaneously.

Secure Forward Aggregation for Vertical Federated Neural Networks

no code implementations28 Jun 2022 Shuowei Cai, Di Chai, Liu Yang, Junxue Zhang, Yilun Jin, Leye Wang, Kun Guo, Kai Chen

In this paper, we focus on SplitNN, a well-known neural network framework in VFL, and identify a trade-off between data security and model performance in SplitNN.
