On Uniform Consistency of Spectral Embeddings
Ruofei Zhao, Songkai Xue, Yuekai Sun
In this paper, we study the convergence of the spectral embeddings obtained from the leading eigenvectors of certain similarity matrices to their population counterparts. We opt to…
Minimax optimal approaches to the label shift problem in non-parametric settings
Subha Maity, Yuekai Sun, Moulinath Banerjee
We study the minimax rates of the label shift problem in non-parametric classification. In addition to the unsupervised setting in which the learner only has access to unlabeled ex…
Statistical Convergence of the EM Algorithm on Gaussian Mixture Models
Ruofei Zhao, Yuanzhi Li, Yuekai Sun
We study the convergence behavior of the Expectation Maximization (EM) algorithm on Gaussian mixture models with an arbitrary number of mixture components and mixing weights. We sh…
Exact post-selection inference, with application to the lasso
Jason D. Lee, Dennis L. Sun, Yuekai Sun +1
We develop a general approach to valid inference after model selection. At the core of our framework is a result that characterizes the distribution of a post-selection estimator c…
On model selection consistency of regularized M-estimators
Jason D. Lee, Yuekai Sun, Jonathan E. Taylor
Regularized M-estimators are used in diverse areas of science and engineering to fit high-dimensional models with some low-dimensional structure. Usually the low-dimensional struct…
