Recurrent Neural Network for Text Classification with ...

Figure 2: Three architectures for modelling text with multi-task learning. Motivated by the success of multi-task learning [Caruana, 1997], we propose three multi-task models to leverage super-vised data from many related tasks. Deep neural model is well suited for multi-task learning since the features learned from a task may be useful for ...
