Rumor Detection with Diverse Counterfactual Evidence

1 code implementation18 Jul 2023 Kaiwei Zhang, Junchi Yu, Haichao Shi, Jian Liang, Xiao-Yu Zhang

Our intuition is to exploit the diverse counterfactual evidence of an event graph to serve as multi-view interpretations, which are further aggregated for robust rumor detection results.

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.

Implicit Neural Representation Learning for Hyperspectral Image Super-Resolution

no code implementations20 Dec 2021 Kaiwei Zhang

Therefore, in this work, we propose a novel HSI reconstruction model based on INR which represents HSI by a continuous function mapping a spatial coordinate to its corresponding spectral radiance values.
