Adaptive HMC: Improve Generation Quality of Score-based Generative Model 韓, 宇 中村, 和幸 人工知能と認知科学 Score-based Generative Modelss (SGMs) is increasingly gaining attention for its ease of training. Langevin MCMC is commonly used in SGMs, but it introduces inefficient random walks. Hamiltonian Monte Carlo (HMC) is a deterministic MCMC method that utilizes an auxiliary variable scheme. Suppressing the random walk is a significant feature of HMC. Therefore, in this study, we employ HMC during the generation process of SGMs. We will present the experimental results of the proposed approach. 情報処理学会 2024-03-01 jpn conference paper https://ipsj.ixsq.nii.ac.jp/records/235898 AN00349328 第86回全国大会講演論文集 2024 1 103 104 https://ipsj.ixsq.nii.ac.jp/record/235898/files/IPSJ-Z86-7C-02.pdf application/pdf 464.5 kB 2024-07-03
