Generative-Ai

Date: April 2023 Locations: Stuttgart · Tübingen · Zurich The Cyber Valley AI Startup Bootcamp is one of Europe’s most prestigious AI entrepreneurship programs, organized by Cyber Valley — Germany’s largest research consortium for artificial intelligence, headquartered across Stuttgart and Tübingen. About the Program The bootcamp brought together researchers, engineers, and entrepreneurs from across Europe to explore the intersection of cutting-edge AI research and real-world product development. Sessions spanned Stuttgart and Tübingen (home to the Max Planck Institute and University of Tübingen) before culminating in Zurich, giving participants exposure to both the academic and startup ecosystems in the DACH region. ...

A diffusion model learns to generate data by reversing a controlled corruption process. During training, clean examples are mixed with noise at different intensities. A neural network learns what noise was added—or, in equivalent parameterizations, what clean sample or velocity produced the noisy input. During generation, the model begins with random noise and repeatedly transforms it into a structured sample. That description is simple, but three details matter: Training does not run the entire noising chain for every example. Any noise level can be sampled directly. The reverse transition is learned because the exact reverse distribution depends on the unknown data distribution. Generation is iterative. Computation within one step is parallelizable, but the denoising steps themselves are sequential. The formulation was introduced by Sohl-Dickstein et al. and made practical for high-quality image synthesis by Ho, Jain, and Abbeel. This article develops the discrete-time DDPM formulation first, then connects it to modern architectures and samplers. ...
