看improved_diffusion/train_util.py/run_loop(),代码似乎是死循环,再看博客IDDPM官方gituhb项目--训练_create_master_params_grads, master_param_to_train_-CSDN博客的评论区也说这里是要手动中止,看损失值合适了停。 defrun_loop(self):while(notself.lr_anneal_stepsorself.step+self.resume_step<self.lr_...
improved-diffusion作为一项关键的前期研究，强调了这些因素对于提升生成效果的重要性，是深入理解AIGC领域发展的重要起点。在improved-diffusion中，通过引入新的方差至目标函数，优化目标成为混合目标，从而提升了模型的似然度。这一策略改善了扩散过程中的噪音比例，采用线性添加噪音的方法，特别是在高分辨率图像...

We present a new regularization approach for Diffusion Basis Functions fitting to estimate in vivo brain the axonal orientation from Diffusion Weighted Magnetic Resonance Images. That method assumes that the observed Magnetic Resonance signal at each voxel is a linear combination of a given diffusion ba...
