Many problems in pattern recognition are focused to learn one main task, Single Task Learning (STL). However, most of them can be formulated from learning several tasks related to the main task at the same time while using a shared representation, Multitask Learning (MTL). In this paper, a new MLT architecture is proposed and its performance is compared with those obtained from other previous schemes used in MTL. This new MTL scheme makes use of private subnetworks to induce a bias in the learning process. The results provided from artificial and real data sets show how the use of this private subnetworks in MTL produces a better generalization capabilities and a faster learning.
