PyTorch中定义模型时,有时候会遇到self.register_buffer('name', Tensor)的操作,该方法的作用是定义一组参数,该组参数的特别之处在于:模型训练时不会更新(即调用 optimizer.step() 后该组参数不会变化,只可人为地改变它们的值),但是保存模型时,该组参数又作为模型参数不可或缺的一部分被保存。 说明: 也就是写...

Our implementations are done in PyTorch Lightning56 with MONAI57, and we trained all tasks on an Nvidia GeForce RTX 3090 GPU using the Adam optimizer with batch-size 64 and learning rate \(10^{-4}\). We add one linear layer to the pre-trained encoder. Only the linear layer is ...
We deploy the ADAM [24] optimizer with a learn- ing rate of 0.0002, 0.5 for β1, and 0.999 for β2. We use the batch size as 32 for all experiments. Besides, the length of the generated video is 16 as did [35, 38]. For weighting parameters o...
