Resnet 50 downsample
WebApr 13, 2024 · 在2016年,何恺明等人提出了ResNet,就很优雅地解决了训练过程中梯度消失的问题 [6]。其基本思想是在网络中引入这样的Residual block: 在前馈的过程中,将输入与输出加和。这使得在反馈过程中计算梯度时,梯度值是大于1的: WebSummary ResNet 3D is a type of model for video that employs 3D convolutions. This model collection consists of two main variants. The first formulation is named mixed convolution (MC) and consists in employing 3D convolutions only in the early layers of the network, with 2D convolutions in the top layers. The rationale behind this design is that motion …
