Consistent Covariance estimation for stratum imbalances under minimization method for covariate-adaptive randomization
Zixuan Zhao, Yanglei Song, Wenyu Jiang +1
Pocock and Simon's minimization method is a popular approach for covariate-adaptive randomization in clinical trials. Valid statistical inference with data collected under the mini…
Truncated LinUCB for Stochastic Linear Bandits
Yanglei Song, Meng zhou
This paper considers contextual bandits with a finite number of arms, where the contexts are independent and identically distributed -dimensional random vectors, and the expecte…
Stratified incomplete local simplex tests for curvature of nonparametric multiple regression
Yanglei Song, Xiaohui Chen, Kengo Kato
Principled nonparametric tests for regression curvature in are often statistically and computationally challenging. This paper introduces the stratified incomplete…
Approximating high-dimensional infinite-order -statistics: statistical and computational guarantees
Yanglei Song, Xiaohui Chen, Kengo Kato
We study the problem of distributional approximations to high-dimensional non-degenerate -statistics with random kernels of diverging orders. Infinite-order -statistics (IOUS…
Change Acceleration and Detection
Yanglei Song, Georgios Fellouris
A novel sequential change detection problem is proposed, in which the goal is to not only detect but also accelerate the change. Specifically, it is assumed that the sequentially c…
Sequential multiple testing with generalized error control: an asymptotic optimality theory
Yanglei Song, Georgios Fellouris
The sequential multiple testing problem is considered under two generalized error metrics. Under the first one, the probability of at least mistakes, of any kind, is controlled…
Asymptotically optimal, sequential, multiple testing procedures with prior information on the number of signals
Yanglei Song, Georgios Fellouris
Assuming that data are collected sequentially from independent streams, we consider the simultaneous testing of multiple binary hypotheses under two general setups; when the number…
Scalable Topical Phrase Mining from Text Corpora
Ahmed El-Kishky, Yanglei Song, Chi Wang +2
While most topic modeling algorithms model text corpora with unigrams, human interpretation often relies on inherent grouping of terms into phrases. As such, we consider the proble…
Scalable and Robust Construction of Topical Hierarchies
Chi Wang, Xueqing Liu, Yanglei Song +1
Automated generation of high-quality topical hierarchies for a text collection is a dream problem in knowledge engineering with many valuable applications. In this paper a scalable…
