最近,本人要做个小东西,使用SVM对8类三维数据进行分类,搜索网上,发现大伙讨论的都是二维数据的二分类问题,遂决定自己研究一番。本人首先参考了opencv的tutorial,网址是:http://docs.opencv.org/doc/tutorials/ml/non_linear_svms/non_linear_svms.html#nonlinearsvms,这也是二维数据的二分类问题。然后通过...

Given an array of integers, every element appears three times except for one. Find that single one.
Note:
Your algorithm should have a linear runtime complexity. Could you implement it without u...

为啥会有SPM→ScSPM呢?原因之一是为了寻找better coding + better pooling的方式提高性能,原因之二就是提高速度。如何提高速度?这里的速度,不是Coding+Pooling的速度,而是分类器的速度。SPM设计的是一个Linear feature,在文章中作者用于实验则...
