STATISTICAL INFERENCE FOR LOW-RANK TENSORS: HETEROSKEDASTICITY, SUBGAUSSIANITY, AND APPLICATIONS
Journal article Annals of Statistics · June 1, 2026 In this paper, we consider inference and uncertainty quantification for low Tucker rank tensors with additive noise in the high-dimensional regime. Focusing on the output of the higher-order orthogonal iteration (HOOI) algorithm, a commonly used algorithm ... Full text CiteIntegrated analysis for electronic health records with structured and sporadic missingness.
Journal article J Biomed Inform · November 2025 OBJECTIVES: We propose a novel imputation method tailored for Electronic Health Records (EHRs) with structured and sporadic missingness. Such missingness frequently arises in the integration of heterogeneous EHR datasets for downstream clinical application ...

Journal article Genome Biol · December 19, 2024 Longitudinal studies are crucial for understanding complex microbiome dynamics and their link to health. We introduce TEMPoral TEnsor Decomposition (TEMPTED), a time-informed dimensionality reduction method for high-dimensional longitudinal data that treat ... Full text Link to item CiteRecent Grants
