CHEM: Estimating and Understanding Hallucinations in Deep Learning for Image Processing

The M3SR architecture, an advancement of the Mamba framework, has been introduced to enhance spectral reconstruction in hyperspectral imaging by addressing limitations in spatial perception and feature extraction. This multi-scale, multi-perceptual model integrates a fusion block within a U-Net structure to improve the analysis of complex image data.

A new deep learning model named ISLA (Ischemic Stroke Lesion Analyzer) has been introduced for the segmentation of acute ischemic stroke lesions in MRI scans. This model leverages the U-Net architecture and incorporates deep supervision, attention mechanisms, and domain adaptation, trained on over 1500 participants from multiple centers.

A recent study published on arXiv investigates the out-of-distribution generalization capabilities of deep-learning surrogates for two-dimensional partial differential equation (PDE) dynamics, particularly under small-data conditions. The research introduces a multi-channel U-Net architecture and evaluates its performance against various models, including ViT and PDE-Transformer, across different PDE families.

A recent study investigates the performance of a U-Net architecture in standalone end-to-end blind deconvolution of astronomical images, without prior knowledge of the Point Spread Function (PSF) or noise characteristics. The research evaluates the model against classical Tikhonov deconvolution and assesses its generalization capability under varying conditions.
