Section I: Matrix Factorization matrix factorization主要用于rec sys中的collaborative filtering中,他被用来给已经构造好的user-item matrix通过分解成两个matrix with latent factor的方式降维度。 matrix factorization in graphical explanation 下面介绍三种matrix decomposition的technique: ...
Matrix Factorization is simply a mathematical tool for playing around with matrices. The Matrix Factorization techniques are usually more effective, because they allow users to discover the latent (hidden)features underlying the interactions between users and items (books). We use singular value decompos...
One hopes then to find a new representation space in which two data points are sufficiently close to each other if they are connected in the graph. To achieve this, we design a new matrix factorization objective function and incorporates the graph structure into it. We also develop a ...

In particular, semi-nonnegative matrix factorization (semi-NMF) has shown promising results in data representation. In this section, we briefly review semi-NMF. Given a nonnegative data matrix X=[x1,x2,⋯,xn]∈Rd×n, NMF aims to find two matrices Z∈ Rd× k and H∈ Rk× n which ...
However, in doing compression, we wish to preserve both the non-negativity and structure of the data. To this end, we explore a recent iterative technique called non-negative matrix factorization (NMF) [1], [4], [5], [6]. This technique preserves much of the structure of the original ...
