在实践中,我发现这两种regularization的方法有一些subtle but critical details,在这里跟大家分享。 如何使用Spectral Normalization 假设,我们有一个包含Spectral Normalization的网络D。对于pytorch可以使用torch.nn.utils.spectral_norm(旧版),或torch.nn.utils.parametrizations.spectral_norm(新版) 实现。 根据习惯不同,...
原因也很简单,因为 Batch norm 的“除方差”和“乘以缩放因子”这两个操作很明显会破坏判别器的 Lipschitz 连续性。 // 五、GAN的谱归一化实现# google用tensorflow实现了谱归一化函数链接 pytorch中有实现好的谱归一化函数torch.nn.utils.spectral_norm(官方文档)(github) importtorch.nnasnnimporttorch# 对线性...
作者所有的实验主要基于PyTorch框架进行,使用了一台配备Nvidia GeForce GTX 3080 GPU的工作站。作者通过在区间{10−4,5×10−4,10−3,5×10−3} 上进行粗略的网格搜索来调整学习率和权重衰减的超参数。将迭代次数设置为500。采用了StepLR调度器,每20个epoch将学习率乘以0.9进行缩减。 另一个常被忽视的问...

Our experiments were conducted using the PyTorch framework in Python on a computing system equipped with a single NVIDIA GeForce RTX 3090 GPU with 24GB memory and an Intel(R) Xeon(R) Silver 4210R CPU. In SCNet, the ConvNeXtBlock is configured with two layers: the first layer has a kernel...
The study in this paper is implemented in the PyTorch environment, using an AMD EPYC 7543 32-Core Processor, 90-GB RAM, and an NVIDIA A40 48-GB GPU server. All experiments are randomly repeated 10 times to take the average to reduce experimental error. Figure 5 The classification ...

This repository contains Python scripts to preprocess MIDI data, train a pre-LayerNorm Music Transformer using PyTorch, as well as to generate MIDI files with a trained (or if you're brave, untrained) Music Transformer. It also contains three of my own trained Music Transformers that can be ...
