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.”

Time-Aware Adaptive Side Information Fusion for Sequential Recommendation

Published:Dec 30, 2025 14:15
1 min read
ArXiv

Analysis

This paper addresses key limitations in sequential recommendation models by proposing a novel framework, TASIF. It tackles challenges related to temporal dynamics, noise in user sequences, and computational efficiency. The proposed components, including time span partitioning, an adaptive frequency filter, and an efficient fusion layer, are designed to improve performance and efficiency. The paper's significance lies in its potential to enhance the accuracy and speed of recommendation systems by effectively incorporating side information and temporal patterns.
Reference

“TASIF integrates three synergistic components: (1) a simple, plug-and-play time span partitioning mechanism to capture global temporal patterns; (2) an adaptive frequency filter that leverages a learnable gate to denoise feature sequences adaptively; and (3) an efficient adaptive side information fusion layer, this layer employs a "guide-not-mix" architecture.”

AI for Primordial CMB B-Mode Signal Reconstruction

Published:Dec 27, 2025 19:20
1 min read
ArXiv

Analysis

This paper introduces a novel application of score-based diffusion models (a type of generative AI) to reconstruct the faint primordial B-mode polarization signal from the Cosmic Microwave Background (CMB). This is a significant problem in cosmology as it can provide evidence for inflationary gravitational waves. The paper's approach uses a physics-guided prior, trained on simulated data, to denoise and delens the observed CMB data, effectively separating the primordial signal from noise and foregrounds. The use of generative models allows for the creation of new, consistent realizations of the signal, which is valuable for analysis and understanding. The method is tested on simulated data representative of future CMB missions, demonstrating its potential for robust signal recovery.
Reference

“The method employs a reverse SDE guided by a score model trained exclusively on random realizations of the primordial low $\ell$ B-mode angular power spectrum... effectively denoising and delensing the input.”
