Online-Updating Regularized Kernel Matrix Factorization Models for Large-Scale Recommender Systems Steffen Rendle, Lars Schmidt-Thieme Machine Learning Lab Institute for Computer Science University of Hildesheim, Germany {srendle, schmidt-thieme}@ismll.uni-hildesheim.de ABSTRACT Regularized matrix factorization models are known to gen- kernel matrix to represent a descriptor set demonstrates its superiority. Given a set of d-dimensional descriptors, a d Г— d kernel matrix is computed with a predeп¬Ѓned kernel function, where each entry is the kernel value between the realization of two descriptor components in this set.

Thus the kernel of A is the same as the solution set to the above homogeneous equations. Subspace properties. The kernel of a m Г— n matrix A over a field K is a linear subspace of K n. That is, the kernel of A, the set Null(A), has the following three properties: Null(A) always contains the zero vector, since A0 = 0. Random Features for Large-Scale Kernel Machines Ali Rahimi and Ben Recht Abstract To accelerate the training of kernel machines, we propose to map the input data to a randomized low-dimensional feature space and then apply existing fast linear methods. Our randomized features are designed so that the inner products of the
