Data Augmentation in Intent Classification: An Introduction

Data Augmentation can boost the performance of an intent classifier. In this post, we will introduce a data augmentation method.

This method is proposed in paper: New Intent Discovery with Pre-training and Contrastive Learning

How to implement data augmentation in intent classification?

This method is simple, it is:

As to a sentence, we can use some words to replace wods in this sentence randomly.

However, there is a problem, how many words should be replaced in a sentence?

From this paper, we can find 25% words that are replaced will make the model get a good performance.
