Inference and Uncertainty Quantification for Streaming -PCA
Haoshu Xu, Hongzhe Li
We address two open questions in streaming PCA via Oja's algorithm: sharp operator-norm convergence for general rank under sub-Gaussian data, and distributional inference for the r…
CGEarthEye:A High-Resolution Remote Sensing Vision Foundation Model Based on the Jilin-1 Satellite Constellation
Zhiwei Yi, Xin Cheng, Jingyu Ma +5
Deep learning methods have significantly advanced the development of intelligent rinterpretation in remote sensing (RS), with foundational model research based on large-scale pre-t…
Test of partial effects for Frechet regression on Bures-Wasserstein manifolds
Haoshu Xu, Hongzhe Li
We propose a novel test for assessing partial effects in Fréchet regression with responses lying on the Bures-Wasserstein manifold. Under the null hypothesis, we show that the stat…
Wasserstein F-tests for Fréchet regression on Bures-Wasserstein manifolds
Haoshu Xu, Hongzhe Li
This paper considers the problem of regression analysis with random covariance matrix as outcome and Euclidean covariates in the framework of Fréchet regression on the Bures-Wasser…
