Optimal Pricing Schemes in the Presence of Social Learning and Costly Reporting

no code implementations14 Nov 2022 Kaiwei Zhang, Xi Weng, Xienan Cheng

A monopoly platform sells either a risky product (with unknown utility) or a safe product (with known utility) to agents who sequentially arrive and learn the utility of the risky product by the reporting of previous agents.

Deep Multi-Branch Aggregation Network for Real-Time Semantic Segmentation in Street Scenes

no code implementations8 Mar 2022 Xi Weng, Yan Yan, Genshun Dong, Chang Shu, Biao Wang, Hanzi Wang, Ji Zhang

This shows that DMA-Net provides a good tradeoff between segmentation quality and speed for semantic segmentation in street scenes.
