Transfer learning via Regularized Linear Discriminant Analysis

no code implementations5 Jan 2025 Hongzhe Zhang, Arnab Auddy, Hongzhe Lee

In this paper, we present novel transfer learning methods via regularized random-effects linear discriminant analysis, where the discriminant direction is estimated as a weighted combination of ridge estimates obtained from both the target and source models.

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.

Proactive Resource Request for Disaster Response: A Deep Learning-based Optimization Model

no code implementations31 Jul 2023 Hongzhe Zhang, Xiaohang Zhao, Xiao Fang, Bintong Chen

Prior resource management research for disaster response overlooks the problem of deciding optimal quantities of resources requested by a local agency.

Transfer Learning with Random Coefficient Ridge Regression

no code implementations28 Jun 2023 Hongzhe Zhang, Hongzhe Li

This paper considers estimation and prediction of random coefficient ridge regression in the setting of transfer learning, where in addition to observations from the target model, source samples from different but possibly related regression models are available.
