Weak convergence of Bayes estimators under general loss functions
Robin Requadt, Housen Li, Axel Munk
We investigate the asymptotic behavior of parametric Bayes estimators under a broad class of loss functions that extend beyond the classical translation-invariant setting. To this…
Online jump and kink detection in segmented linear regression: Statistical optimality meets computational efficiency
Annika Hüselitz, Housen Li, Axel Munk
We consider the problem of sequential (online) estimation of a single change point in a piecewise linear regression model under a Gaussian setup. We demonstrate that certain CUSUM-…
Adaptive monotonicity testing in sublinear time
Housen Li, Zhi Liu, Axel Munk
Modern large-scale data analysis increasingly faces the challenge of achieving computational efficiency as well as statistical accuracy, as classical statistically efficient method…
Distributional limits of graph cuts on discretized grids
Leo Suchan, Housen Li, Axel Munk
Graph cuts are among the most prominent tools for clustering and classification analysis. While intensively studied from geometric and algorithmic perspectives, graph cut-based sta…
