Factorization Machines Study notes (ii) model equations

     
    Recently learned an algorithm called Factorization Machines (FM), which can predict arbitrary real-valued vectors. The main advantages include: 1) can be used in highly sparse data scenarios, 2) with linear computational complexity. In this paper, the FM framework is briefly introduced, and its training algorithm-random gradient descent (SGD) method and alternating least squares (ALS) method are presented in detail.
