Robust Relative Error Estimation [PDF]

open access: yesEntropy, 2018
Relative error estimation has been recently used in regression analysis. A crucial issue of the existing relative error estimation procedures is that they are sensitive to outliers.

Robust Optical Flow Estimation [PDF]

open access: yesImage Processing On Line, 2013
n this work, we describe an implementation of the variational method proposed by Brox etal. in 2004, which yields accurate optical flows with low running times.

Robust Estimation via Robust Gradient Estimation [PDF]

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2020
SummaryWe provide a new computationally efficient class of estimators for risk minimization. We show that these estimators are robust for general statistical models, under varied robustness settings, including in the classical Huber ε-contamination model, and in heavy-tailed settings.

Robust ΔΔct estimate

open access: yesGenomics, 2021
The ΔΔct method estimates fold change in gene expression data from RT-PCR assay. The ΔΔct estimate aggregates replicates using mean and standard deviation (sd) and is not robust to outliers which are in practice often removed before the non-outlying replicates are aggregated. The alternative of using robust statistics such as median and median absolute

Robust Estimation of Optical Phase Varying as a Continuous Resonant Process [PDF]

open access: yes, 2013
It is well-known that adaptive homodyne estimation of continuously varying optical phase provides superior accuracy in the phase estimate as compared to adaptive or non-adaptive static estimation.

Robust Loop Closure Selection Based on Inter-Robot and Intra-Robot Consistency for Multi-Robot Map Fusion

open access: yesRemote Sensing, 2023
In multi-robot simultaneous localization and mapping (SLAM) systems, the system must create a consistent global map with multiple local maps and loop closures between robot poses.

Sub-Bottom Sediment Classification Using Reliable Instantaneous Frequency Calculation and Relaxation Time Estimation

open access: yesRemote Sensing, 2021
The shift in IF (instantaneous frequency) series and the corresponding relaxation time have the potential to characterize sediment properties. However, these attributes derived from SBP (sub-bottom profiler) data are seldom used for offshore site ...

Robust Direction Estimation

open access: yesThe Annals of Statistics, 1992
The study of the stability of parameter estimates for directional data dates back to the late sixties and this paper is an interesting contribution to this domain. The authors consider rotationally symmetric models for directional data with axis of rotation \(\mu\) and concentration parameter \(\kappa\). The prototype is the von Mises distribution. The

Msplit Estimation Approach to Modeling Vertical Terrain Displacement from TLS Data Disturbed by Outliers

open access: yesRemote Sensing, 2022
Terrestrial laser scanning (TLS) is a modern measurement technique that provides a point cloud in a relatively short time. TLS data are usually processed using different methods in order to obtain the final result (infrastructure or terrain models ...
