• ls是单词list的简写，Linux有些命令的名字大多采用单词简写，比如rm命令是remove的简写，而mv命令则是move的简写，还有cp=copy，chown=change owner等等。

在神经网络中，我们知道卷积层通过卷积核和原始特征的线性结合得到输出特征，由于卷积核通常是局部的，为了增加感受野，往往采取堆叠卷积层的方式，实际上这种处理方式并不高效。同时，计算机视觉的很多任务都是由于语义信息不足从而影响最终的性能。自注意力机制通过捕捉全局的信息来获得更大的感受野和上下文信息。

命令行参数(这定义贼TM神奇)

在欧式空间中，这个问题显然是“只有一条”，然而在非欧空间中，这个问题就不一定了。
马鞍形的双曲抛物面，就是一个非欧空间的例子。现实中，非欧空间的例子还很多。
下图中，粉色和黄色线都平行于蓝线，且都经过同一点。更重要的是，蓝色和黄色的平行线并非
与欧式空间中的平行线一样处处距离相等。

IoU threshold

(1)produce many object proposals

when the IoU threshold is small,such as 0.1,the result is that two boxes will become one box

when the IoU threshold is large,such as 0.6,so that getting the wrong result
