Recently, neuralbased models for multi-task learning have become very popular, ranging from computer vision (Misra et al., 2016;Zhang et al., 2014) to natural language processing (Collobert and Weston, 2008;Luong et al., 2015), since they provide a convenient way of combining information from multiple tasks.
