【论文笔记】Training Very Deep Networks - Highway Networks

目标: 怎么训练很深的神经网络 然而过深的神经网络会造成各种问题,梯度消失之类的,导致很难训练 作者利用了类似LSTM的方法,通过增加gate来控制transform前和transform后的数据的比例,称为Highway network 至于为什么会有效...大概和LSTM会有效的原因一样吧. 方法: 首先是普通的神经网络,每一层H从输入x映射到输出y,H通常包含一个仿射变换和一个非线性变换,如下 在这个基础上,highway network添加了两个gate 1)T:trasform gat…

Deep Networks : Overview

Overview In the previous sections, you constructed a 3-layer neural network comprising an input, hidden and output layer. While fairly effective for MNIST, this 3-layer model is a fairly shallow network; by this, we mean that the features (hidden lay…

Quantization aware training 量化背后的技术——Quantization and Training of Neural Networks for Efficient Integer-Arithmetic-Only Inference

1,概述 模型量化属于模型压缩的范畴,模型压缩的目的旨在降低模型的内存大小,加速模型的推断速度(除了压缩之外,一些模型推断框架也可以通过内存,io,计算等优化来加速推断). 常见的模型压缩算法有:量化,剪枝,蒸馏,低秩近似以及紧凑模型设计(如mobileNet)等操作.但在这里有些方法只能起到缩减模型大小,而起不到加速的作用,如稀疏化剪枝.而在现代的硬件设备上,其实更关注的是模型推断速度.今天我们就讲一种既能压缩模型大小,又能加速模型推断速度:量化. 量化一般可以分为两种模式:训练后的量化(po…
