Published in 2017 at "Journal of Mathematical Imaging and Vision"

DOI: 10.1007/s10851-017-0747-z

Abstract: The aim of this paper was to introduce and study a two-step debiasing method for variational regularization. After solving the standard variational problem, the key idea is to add a consecutive debiasing step minimizing the… read more here.

Published in 2023 at "Statistics"

DOI: 10.1080/02331888.2023.2201504

Abstract: In this paper, we reconstruct the local linear threshold estimator for the drift coefficient of a semimartingale with jumps. Under mild conditions, we provide the asymptotic normality of our estimator in the presence of finite… read more here.

Published in 2022 at "IEEE Internet of Things Journal"

DOI: 10.1109/jiot.2022.3194897

Abstract: This article develops a robust source localization method using time delay and Doppler shift measurements, where the sensor motion effect accompanied by sensor location errors cannot be ignored. We begin by transforming the time delay… read more here.

Published in 2019 at "Statistical Methods in Medical Research"

DOI: 10.1177/0962280218771717

Abstract: The reduction of the mean or median bias of the maximum likelihood estimator in regular parametric models can be achieved through the additive adjustment of the score equations. In this paper, we derive the adjusted… read more here.
