目录 引 主要结果 定理2,3 定理4 直观解释 Recovering Low-Rank Matrices From Few Coefficients In Any Basis-David Gross 引 依旧是一个重构矩阵的问题,这篇论文的符号有些奇怪,注意一下.假设有一个矩阵\(\rho \in \mathbb{R}^{n \times n}\),其秩为\(r \ll n\).有一组基\(w_a, a=1,\ldots, n^2\),是已知的.假设我们观测到的是,一组内积\(\{ (\rho,…

一.向量化:低秩矩阵分解 之前我们介绍了协同过滤算法,本节介绍该算法的向量化实现,以及说说有关该算法可以做的其他事情. 举例:1.当给出一件产品时,你能否找到与之相关的其它产品.2.一位用户最近看上一件产品,有没有其它相关的产品,你可以推荐给他. 我们将要做的是:实现一种选择的方法,写出协同过滤算法的预测情况. 我们有关于五部电影的数据集,我将要做的是,将这些用户的电影评分,进行分组并存到一个矩阵中. 我们有五部电影,以及四位用户,那么 这个矩阵…

目录 前言 文章概述 固定\(\widetilde{\mathrm{v}}\) 固定\(\widetilde{\mathrm{u}}\) Adjusted Variance 前言 这篇文章用的也是交替算法,不得不说,这个东西太好用了,变来变去怎么都能玩出花来.这篇论文的关键之处,我感觉是对adjusted variance的算法,比较让人信服. 文章概述 \(X是中心化的样本矩阵\) 考虑下面的一个最优分解(F-范数). 本文采取的也是一种搜索算法,每次计算一个载荷向量,所以,每次都处理的是ra…

如上图中的predicted ratings矩阵可以分解成X与ΘT的乘积,这个叫做低秩矩阵分解. 我们先学习出product的特征参数向量,在实际应用中这些学习出来的参数向量可能比较难以理解,也很难可视化出来,但是它们是做为区分不同电影的特征 怎么来区分电影i与电影j是否相似呢?就是判断X(i)与X(j)之间的距离是否小来判断.这样在一个用户看了或者买了一部电影后,我们可以给他推荐相似的电影. 总结: 1>用向量化的计算来对所有的用户所有的电影进行评分计算 2>通过学习特征参数,如何找到相关的…
