Multi-task Learning & End-to-End

Combining two or more ABSA's subtasks in one framework to produce results is an intutively effective way for industrial application. There are three patterns of multi-task learning: pipeline, joint and end-to-end model. For pipeline pattern, the framework complete subtasks in more than one step, using the result of last step to guide the next step's output, which might lead to error propogation problem. Joint model processes the data with shared layers to extract universal semantic features for all subtasks. Then model outputs results of different tasks through task-specific layers. End-to-end model complete tasks like sequence labeling.
