Small sample learning and its application in the US group scene

Each business of Meituan has a wealth of NLP scenarios, and the construction of models in these scenarios requires a lot of annotation resources and is costly. Small sample learning is dedicated to training a better model when data resources are scarce. This article introduces some existing methods from active learning, data enhancement, semi-supervised learning, domain migration, integrated learning & self-training, and experiments in the Meituan scene, and the effect has also been improved. I hope to be helpful or inspiring to students who are engaged in related research.
