Finite-Time Observability of Oscillatory Instabilities in Synchronous p-bit Dynamics
Naoya Onizawa, Shunsuke Koshita, Takahiro Hanyu
Synchronous update schemes in p-bit annealing offer a natural route to massive parallelism, but they can also induce period-2 oscillations that degrade optimization performance. In…
M-type penalized splines with auxiliary scale estimation
Ioannis Kalogridis, Stefan Van Aelst
Penalized spline smoothing is a popular and flexible method of obtaining estimates in nonparametric regression but the classical least-squares criterion is highly susceptible to mo…
Robust functional regression based on principal components
Ioannis Kalogridis, Stefan Van Aelst
Functional data analysis is a fast evolving branch of modern statistics and the functional linear model has become popular in recent years. However, most estimation methods for thi…
Fast Computation of Robust Subspace Estimators
Holger Cevallos-Valdiviezo, Stefan Van Aelst
Dimension reduction is often an important step in the analysis of high-dimensional data. PCA is a popular technique to find the best low-dimensional approximation of high-dimension…
Propagation of outliers in multivariate data
Fatemah Alqallaf, Stefan Van Aelst, Victor J. Yohai +1
We investigate the performance of robust estimates of multivariate location under nonstandard data contamination models such as componentwise outliers (i.e., contamination in each…
High-Breakdown Robust Multivariate Methods
Mia Hubert, Peter J. Rousseeuw, Stefan Van Aelst
When applying a statistical method in practice it often occurs that some observations deviate from the usual assumptions. However, many classical methods are sensitive to outliers.…
