Paraphrase the following text with advanced English words for a scientific paper: Neural network based methods have obtained great progress on a variety of natural language processing tasks. However, in most previous works, the models are learned based on single-task supervised objectives, which often suffer from insufficient training data. In this paper, we use the multi-task learning framework to jointly learn across multiple related tasks.

In recent years , neural network - based approaches have demonstrated remarkable advance ments in the field of natural language processing . However , the majority of prior research has focused on single - task super vised learning objectives , which are frequently constr ained by limited training data . In this study , we propose the util ization of a multi - task learning framework to con current ly learn across multiple related tasks . </s>
