Neural Networks:Momentum

一、目的

加快参数的收敛速度。

二、做法

另第t次的权重更新对第t+1次的权重更新造成影响。

从上式可看出,加入momentum后能够保持权重的更新方向,同时加快收敛。通常alpha的取值为[0.7, 0.95]

论文笔记之:Learning Multi-Domain Convolutional Neural Networks for Visual Tracking

Learning Multi-Domain Convolutional Neural Networks for Visual Tracking CVPR 2016 本文提出了一种新的CNN 框架来处理跟踪问题.众所周知,CNN在很多视觉领域都是如鱼得水,唯独目标跟踪显得有点“慢热”,这主要是因为CNN的训练需要海量数据,纵然是在ImageNet 数据集上微调后的model 仍然不足以很好的表达要跟踪地物体,因为Tracking问题的特殊性,至于怎么特殊的,且听细细道来. 目标跟踪之所以很少被 C
