虽然文件名称是TestOther.java,但是由于主方法是在Demo类中,所以执行时直接执行java Demo命令即可,找的是生成后的*.class文件。 (3)public static void main(String args[])是程序的主方法,即所有的程序都会以此方法作为起点并运行下来。 (4)“int num=10”意思是定义一个整型变量num,int 表示变量的类型是整型,...
所以batch size其实是为了保证说 你选取的样本量 足够多使得这个batch计算得到的梯度跟你用所有sample计算...
极端情况下，一个batch里只有一个类别——不极端的情况下，一个batch也有可能覆盖不了所有类别。
