机器学习笔记1——深度学习的数据库和目前一些流行的软件

一、首先我先查阅了深度学习的数据库：

1、mnist手写字符库

2、cifar10(caffe.theano)数据集分为5个训练块和1个测试块，每个块有10000个图像。测试块包含从每类随机选择的1000个图像。训练块以随机的顺序包含这些图像，但一些训练块可能比其它类包含更多的图像。训练块每类包含5000个图像。类与类之间完全互斥。

airplane,automobile,bird,cat,deer,dog,frog,horse,ship,truck

3、cifar100（有python版，matlab版，和用于c++的二值化版本）

数据集包含100小类，每小类包含600个图像，其中有500个训练图像和100个测试图像。100类被分组为20个大类。每个图像带有1个小类的“fine”标签和1个大类“coarse”标签。

4、imagenet
大规模视觉识别挑战的识别任务之一便是对 1000 类、120 万张互联网图像进行分类。

物体检测是视觉挑战中最难的任务，它要求从四万张图像中准确检测到 200 类物体的具体位置，并且一幅图像往往包含多个不同类别的物体。
