»An adaptive subsampled trust-region method for machine learning problems«

We propose a new algorithm for solving large-scale non-convex machine learning problems. The algorithm is based on the classical trust-region framework and incorporates gradient and hessian information of the objective function obtained through subsampling. The subsample size is adaptively increased during the optimization process. We present a theoretical convergence result and compare the empirical performance of the algorithm on convex and non-convex machine learning problems to existing methods.


Hierzu ergeht herzliche Einladung.
