Thermodynamic Brainpower: Tiny-Energy Image Generation with Noise-Driven Computing

Scientists report a generative thermodynamic computer that uses thermal noise to produce images from random data, mimicking AI neural networks but with energy use orders of magnitude lower. By leveraging probabilistic computing and diffusion-like dynamics (via Langevin-based calculations) and tuning coupling strengths in a network, the system retrieves or creates images from noise, offering a physics-based path to energy-efficient AI-like tasks and new insights into learning.

AI diffusion model maps multiple synthesis routes to speed up materials discovery

MIT researchers trained a diffusion-based AI, DiffSyn, on 23,000 material-synthesis recipes to map a target structure to multiple viable synthesis routes, enabling rapid exploration of temperatures, times, and precursor ratios. In tests with zeolites, DiffSyn suggested promising pathways and helped synthesize a new zeolite with improved thermal stability, reducing trial‑and‑error to a rapid initial search. This one‑to‑many approach better matches experimental reality and could extend to other materials, though high‑quality data remain a bottleneck; future work includes autonomous experiments and broader material classes.

Apple Launches Innovative Coding Language Model

Apple released an open-source AI model called DiffuCode-7B-cpGRPO that uses a diffusion-based approach for code generation, allowing faster and more globally coherent code output by generating out of order and refining multiple chunks simultaneously, building on Alibaba's foundation model and recent research in diffusion architectures.

Researchers Reveal Secrets of AI Creativity

Researchers have discovered that the apparent creativity of diffusion models in AI image generation stems from deterministic imperfections in their denoising process, revealing that their 'creativity' is an inevitable outcome of their architecture, similar to biological morphogenesis processes. This insight could impact future AI development and our understanding of human creativity.

"New AI Techniques for Image Compression and Visual Question Answering"

Google researchers proposed a method that combines a standard autoencoder with a diffusion process to efficiently compress high-quality images using score-based generative models. The proposed method outperforms several recent generative approaches in terms of image quality and preserves details much better compared to state-of-the-art approaches. The study revealed specific details that can be useful for future research in this domain, such as the impact of noise schedule and the amount of noise injected during image generation.
