Augmenting Ground-Level PM2.5 Prediction via Kriging-Based Pseudo-Label Generation

no code implementations16 Jan 2024 Lei Duan, Ziyang Jiang, David Carlson

We show that the proposed data augmentation strategy helps enhance the performance of the state-of-the-art convolutional neural network-random forest (CNN-RF) model by a reasonable amount, resulting in a noteworthy improvement in spatial correlation and a reduction in prediction error.

Causal Mediation Analysis with Multi-dimensional and Indirectly Observed Mediators

no code implementations13 Jun 2023 Ziyang Jiang, Yiling Liu, Michael H. Klein, Ahmed Aloui, Yiman Ren, Keyu Li, Vahid Tarokh, David Carlson

This is important in many scientific applications to identify the underlying mechanisms of a treatment effect.

Domain Adaptation via Rebalanced Sub-domain Alignment

no code implementations3 Feb 2023 Yiling Liu, Juncheng Dong, Ziyang Jiang, Ahmed Aloui, Keyu Li, Hunter Klein, Vahid Tarokh, David Carlson

To address this limitation, we propose a novel generalization bound that reweights source classification error by aligning source and target sub-domains.

Estimating Causal Effects using a Multi-task Deep Ensemble

1 code implementation26 Jan 2023 Ziyang Jiang, Zhuoran Hou, Yiling Liu, Yiman Ren, Keyu Li, David Carlson

A number of methods have been proposed for causal effect estimation, yet few have demonstrated efficacy in handling data with complex structures, such as images.
