Nonlinear Noise2Noise for HDR Image Denoising

Published:Dec 31, 2025 11:30
1 min read
ArXiv

Analysis

This paper addresses a key limitation of the Noise2Noise method, which is the bias introduced by nonlinear functions applied to noisy targets. It proposes a theoretical framework and identifies a class of nonlinear functions that can be used with minimal bias, enabling more flexible preprocessing. The application to HDR image denoising, a challenging area for Noise2Noise, demonstrates the practical impact of the method by achieving results comparable to those trained with clean data, but using only noisy data.
Reference

“The paper demonstrates that certain combinations of loss functions and tone mapping functions can reduce the effect of outliers while introducing minimal bias.”

Multipliers for Stability and Power Gain in Lurye Systems

Published:Dec 30, 2025 20:22
1 min read
ArXiv

Analysis

This paper investigates the use of dynamic multipliers for analyzing the stability and performance of Lurye systems, particularly those with slope-restricted nonlinearities. It extends existing methods by focusing on bounding the closed-loop power gain, which is crucial for noise sensitivity. The paper also revisits a class of multipliers for guaranteeing unique and period-preserving solutions, providing insights into their limitations and applicability. The work is relevant to control systems design, offering tools for analyzing and ensuring desirable system behavior in the presence of nonlinearities and external disturbances.
Reference

“Dynamic multipliers can be used to guarantee the closed-loop power gain to be bounded and quantifiable.”

Kalman Filter for Steer-by-Wire Disturbance Estimation

Published:Dec 29, 2025 16:44
1 min read
ArXiv

Analysis

This paper addresses a practical problem in steer-by-wire systems: mitigating high-frequency disturbances caused by driver input. The use of a Kalman filter is a well-established technique for state estimation, and its application to this specific problem is novel. The paper's contribution lies in the design and evaluation of a Kalman filter-based disturbance observer that estimates driver torque using only motor state measurements, avoiding the need for costly torque sensors. The comparison of linear and nonlinear Kalman filter variants and the analysis of their performance in handling frictional nonlinearities are valuable. The simulation-based validation is a limitation, but the paper acknowledges this and suggests future work.
Reference

“The proposed disturbance observer accurately reconstructs driver-induced disturbances with only minimal delay 14ms. A nonlinear extended Kalman Filter outperforms its linear counterpart in handling frictional nonlinearities.”

Renormalization Group Analysis of Graphene Bilayers

Published:Dec 29, 2025 10:21
1 min read
ArXiv

Analysis

This paper applies a nonperturbative renormalization group (NPRG) approach to study thermal fluctuations in graphene bilayers. It builds upon previous work using a self-consistent screening approximation (SCSA) and offers advantages such as accounting for nonlinearities, treating the bilayer as an extension of the monolayer, and allowing for a systematically improvable hierarchy of approximations. The study focuses on the crossover of effective bending rigidity across different renormalization group scales.
Reference

“The NPRG approach allows one, in principle, to take into account all nonlinearities present in the elastic theory, in contrast to the SCSA treatment which requires, already at the formal level, significant simplifications.”

Data-Driven Economic Predictive Control for Nonlinear Systems

Published:Dec 29, 2025 03:25
1 min read
ArXiv

Analysis

This paper presents a novel data-driven control approach for optimizing economic performance in nonlinear systems, addressing the challenges of nonlinearity and constraints. The use of neural networks for lifting and convex optimization for control is a promising combination. The application to industrial case studies strengthens the practical relevance of the work.
Reference

“The online control problem is formulated as a convex optimization problem, despite the nonlinearity of the system dynamics and the original economic cost function.”

Comparing Noise Models for Simulating Westerly Wind Bursts in ENSO

Published:Dec 27, 2025 21:44
1 min read
ArXiv

Analysis

This paper investigates different noise models to represent westerly wind bursts (WWBs) within a recharge oscillator model of ENSO. It highlights the limitations of the commonly used Gaussian noise and proposes Conditional Additive and Multiplicative (CAM) noise as a better alternative, particularly for capturing the sporadic nature of WWBs and the asymmetry between El Niño and La Niña events. The paper's significance lies in its potential to improve the accuracy of ENSO models by better representing the influence of WWBs on sea surface temperature (SST) dynamics.
Reference

“CAM noise leads to an asymmetry between El Niño and La Niña events without the need for deterministic nonlinearities.”
