关于DL4J

关于《DL4J实战》系列

本篇概览

  1. 确定环境和版本信息
  2. 创建名为<font color="blue">dl4j-tutorials</font>的maven工程作为父工程,后面整个系列的代码都是dl4j-tutorial的子工程
  3. 创建名为<font color="blue">commons</font>的子工程,这里面是一些常用的工具代码,例如下载数据集、绘图等

  1. DataUtilities:下载和解压指定地址对应的文件
  2. DownloaderUtility:DL4J为我们准备了丰富的数据集(例如150个鸢尾花数据,带标签),这些内容保存在云端(AZURE),通过DownloaderUtility可以很方便的下载和解压这些数据集
  3. PlotUtil:绘制二维图形
  4. VAEPlotUtil:绘制变分自编码图形
