Semisupervised score based matching algorithm to evaluate the effect of public health interventions

no code implementations19 Mar 2024 Hongzhe Zhang, Jiasheng Shi, Jing Huang

We proposed a novel one-to-one matching algorithm based on a quadratic score function $S_{\beta}(x_i, x_j)= \beta^T (x_i-x_j)(x_i-x_j)^T \beta$.

Bias of AI-Generated Content: An Examination of News Produced by Large Language Models

no code implementations18 Sep 2023 Xiao Fang, Shangkun Che, Minjia Mao, Hongzhe Zhang, Ming Zhao, Xiaohang Zhao

We then apply each examined LLM to generate news content with headlines of these news articles as prompts, and evaluate the gender and racial biases of the AIGC produced by the LLM by comparing the AIGC and the original news articles.
