全称《Improving regularized singular value decomposition for collaborative filtering》发布于07年的KDD,作者是 A. Paterek。是一种用于评分预测的factored item-item CF方法,以RMSE方法为evaluation。 通过学习两个low-rank的矩阵P和Q, P\in R^{m *
for k = max(i-floor(rmin),1):min(i+floor(rmin),nelx) for l = max(j-floor(rmin),1):min(j+floor(rmin),nely)(floor为向下取整函数。此处两个for循环作用是遍历附近单元,附近单元即为距离当前中心单元距离小于等于rmin的所有单元,但是具体是怎么做到遍历附近单元的我还是比较模糊。以下将对附近单元...

临时性泄露,指的是该释放的内存资源没有及时释放,对应的内存资源仍然有机会在更晚些时候被释放,即便如此在内存资源紧张情况下,也会是个问题。这类主要是string、slice底层buffer的错误共享,导致无用数据对象无法及时释放,或者defer函数导致的资源没有及时释放。
