CoD: A Diffusion Foundation Model for Image Compression

Recent advancements in AI, particularly with generative models like StyleGAN2 and Stable Diffusion, have raised concerns about the authenticity of satellite imagery, which is crucial for scientific and security analyses. A study has compared Convolutional Neural Networks (CNNs) and Vision Transformers (ViTs) for detecting AI-generated satellite images, revealing that ViTs outperform CNNs in accuracy and robustness.

SYNAPSE is a newly introduced framework that integrates an adapter and fine-tuning techniques to enhance high-fidelity EEG synthesis from a CLIP-aligned encoder. This two-stage approach aims to improve the representation of EEG signals, addressing challenges such as noise and inter-subject variability that have hindered previous image generation methods based on brain signals.

The paper presents DICE, a novel approach that distills Classifier-Free Guidance (CFG) into text embeddings, significantly reducing computational complexity while maintaining high-quality image generation in text-to-image diffusion models. This method addresses the common issue of misalignment between text prompts and generated images, which has been a challenge in the field.

A new paradigm called SpecDiff has been introduced to accelerate diffusion model inference by utilizing self-speculation, which incorporates future information alongside historical data. This approach aims to enhance accuracy and speed in the inference process by employing a training-free multi-level feature caching strategy, including a feature selection algorithm based on self-speculative information.

A new generative model named VeilGen has been proposed to address the challenge of veiling glare in compact optical systems, which is often exacerbated by stray-light scattering from non-ideal surfaces. This model learns to simulate veiling glare by estimating optical transmission and glare maps from target images in an unsupervised manner, marking a significant advancement in lens performance enhancement.

A new framework called SAE Debias has been introduced to address gender bias in text-to-image (T2I) generation models, particularly those that generate stereotypical associations between professions and gendered subjects. This model-agnostic approach utilizes a k-sparse autoencoder to identify and suppress biased directions during image generation, aiming for more gender-balanced outputs without requiring model-specific adjustments.
