• Abstract: The idea of using multi-task learning approaches to address the joint extraction of entity and relation is motivated by the relatedness between the entity recognition task and the relation classification task. Existing methods using multi-task learning techniques to address the problem learn interactions among the two tasks through a shared network, where the shared information is passed into the task-specific networks for prediction. However, such an approach hinders the model from learning explicit interactions between the two tasks to improve the performance on the individual tasks. As a solution, we design a multi-task learning model which we refer to as recurrent interaction network which allows the learning of interactions dynamically, to effectively model task-specific features for classification. Empirical studies on two real-world datasets confirm the superiority of the proposed model.

  Multitask learning enforces multiple learning tasks to share knowledge to improve their generalization abilities. Modern deep multitask learning can jointly learn latent features and task sharing, but they are obscure in task relation. This paper proposes a new multitask learning framework that jointly learns latent features and explicit task relations.

  Entity-relation extraction aims to jointly solve named entity recognition (NER) and relation extraction (RE) Recent approaches use either one-way sequential information propagation in a pipeline manner or two-way implicit interaction with a shared encoder. We propose a novel and unified cascade framework that combines the advantages of both sequential information propagation and implicit interaction.

  In dialog system, dialog act recognition and sentiment classification are two correlative tasks.

We propose a Deep Co-Interactive Relation Network (DCR-Net) to explicitly consider the cross-impact and model the interaction between the two tasks.

  Two common challenges in developing multi-task models are often overlooked in literature. First, enabling the model to be inherently incremental, continuously incorporating information from new tasks without forgetting the previously learned ones (incremental learning) Second, eliminating adverse interactions amongst tasks, which has been shown to significantly degrade the single-task performance in a multi-task setup (task interference)

  We introduce a cascade architecture for a multi-stage, coarse-to-fine HOI understanding. At each stage, an instance localization network progressively refines HOI proposals and feeds them into an interaction recognition network. With our carefully-designed human-centric relation features, these two modules work collaboratively towards effective interaction understanding.
