这个残差网络结构非常的经典,所以有不少后续的研究都是基于这个网络的改进,这一篇就来说一说其中的一个经典改进:随机动态网络——Stochastic Depth。 论文:Deep Networks with Stochastic Depth 论文提供了基于lua的代码:github.com/yueatsprogra 基本结构 论文的基本出发点还是想解决如下几个深度网络中的关键问题: 梯度...
时间来到2016年,也就是ResNet被提出的下一年,清华的黄高(也是DenseNet的提出者)在EECV会议上提出了Stochastic Depth(随机深度网络)。这个网络主要是针对ResNet训练时做了一些优化,即随机丢掉一些层,优化了速度和性能(有点类似于Dropout的效果?)。论文原文见附录。 背景 ResNet这个里程碑式的创新对AI领域带来了深远的...
一、论文核心 Deep Networks with Stochastic Depth 这篇论文主要提出了一种训练 ResNet 的新方式,即随机深度(Stochastic Depth)的方式。Stochastic Depth 的理念和 Dropout 类似,将 ResNet 看作多个 ResNet 的集合,只不过后者是在训练时随机失活一些神经元,测试时使用完整的网络;前者是随机失活一些卷积层,或者更准...
本项目是基于Stochastic Depth的基于cifar10数据集的ResNet110模型在 Paddle 2.x上的开源实现。该模型有3个Layer,每个Layer分别由18个BasicBlock组成,每个BasicBlock由两个conv-bn-relu和skip connection组成,其中按论文在每个mini-batch进行按照论文公式计算出的linear_decay的各block的drop_rate(论文中是保留率,1-dro...
From Table 1, we can have the following observations.First, our proposed PID optimizer achieves lower test errors than SGD-Momentum for all the used CNN architectures on both the two CIFAR datasets, except for ResNet with depth 1202. Second, PID optimizer converges faster (with less Epochs) ...
Sideways[Sideways: Depth-parallel training of video models,Gradient forward-propagation for large-scale temporal video modelling]中,每当有新激活可用时,就会覆盖原始激活,但这只能应用于因果模型。这也可以降低内存消耗。 方案动机 实验观察 作者们展示了在Kinetics-400上的视频Swin的激活图和梯度图。作者们假设完...
