Framework for Multi-task Multiple Kernel Learning and Applications in Genome Analysis

no code implementations30 Jun 2015 Christian Widmer, Marius Kloft, Vipin T Sreedharan, Gunnar Rätsch

We present a general regularization-based framework for Multi-task learning (MTL), in which the similarity between tasks can be learned or refined using $\ell_p$-norm Multiple Kernel learning (MKL).
