报告简介：

Deep Learning has emerged as a powerful tool for addressing complex scientific challenges, particularly in the domains of image generation, parameter estimation, and large-scale data analysis within gravitational theory and cosmological research. Meanwhile, extracting information about the universe directly from observational and simulated datasets, without relying on prior assumptions, has become increasingly significant. This presentation provides an overview of the recent advancements made by our research group in applying novel deep learning methodologies to cosmological studies. Specifically, I will introduce the recently proposed Branch-Corrected Denoising Diffusion Model and its application in black hole image generation. Furthermore, I will discuss the reconstruction of the Hubble parameter based on the Ef-KAN model recently developed by our team, along with our research on enhancing cosmological parameter estimation using Long Short-Term Memory Networks.
