Underwater image restoration and enhancement are essential for correcting color distortion and restoring details in images, which are crucial for various underwater visual tasks. Current deep learning methods face challenges due to the lack of high-quality paired datasets, as pristine reference labels are hard to obtain in underwater environments. This paper proposes a novel approach that utilizes in-air natural images as reference targets, translating them into underwater-degraded versions to create synthetic datasets that provide authentic supervision for model training.

MicroEvoEval is introduced as a systematic evaluation framework aimed at predicting image-based microstructure evolution.

Flood prediction is essential for emergency planning and response to reduce human and economic losses. Traditional hydrodynamic models create high-resolution flood maps but are computationally intensive and impractical for real-time applications. Recent studies using convolutional neural networks for flood map super-resolution have shown good accuracy but lack generalizability. This paper introduces a novel approach using latent diffusion models to enhance coarse-grid flood maps, achieving fine-grid accuracy while significantly reducing inference time.

Meta-SimGNN is a novel WiFi localization system that combines graph neural networks with meta-learning to enhance localization generalization and robustness. It addresses the limitations of existing deep learning-based localization methods, which primarily focus on environmental variations while neglecting the impact of device configuration changes. By introducing a fine-grained channel state information (CSI) graph construction scheme, Meta-SimGNN adapts to variations in the number of access points (APs) and improves usability in diverse scenarios.

The Cross-Modal Compositional Self-Distillation (CCSD) framework has been proposed to enhance brain tumor segmentation from multi-modal MRI scans. This method addresses the challenge of missing modalities in clinical settings, which can hinder the performance of deep learning models. By utilizing a shared-specific encoder-decoder architecture and two self-distillation strategies, CCSD aims to improve the robustness and accuracy of segmentation, ultimately aiding in clinical diagnosis and treatment planning.

The paper presents a Doppler Invariant Convolutional Neural Network (CNN) designed for automatic signal classification in radio spectrum monitoring. It addresses the limitations of existing deep learning models that rely on Doppler augmentation, which can hinder training efficiency and interpretability. The proposed architecture utilizes complex-valued layers and adaptive polyphase sampling to achieve frequency bin shift invariance, demonstrating consistent classification accuracy with and without random Doppler shifts using a synthetic dataset.

This study investigates the impact of tokenizer design on the performance of time series foundation models for forecasting. It emphasizes the significance of scaling and quantization strategies, revealing that the configuration of tokenizers is crucial for the model's representational capacity and stability. The research demonstrates that pretrained models benefit from well-designed tokenizers, especially with smaller vocabularies, while misaligned tokenization can negate the advantages of pretraining.
