Reducing cohort bias in natural language understanding systems with targeted self-training scheme (2023.acl-industry)
Copied to clipboard
| Challenge: | In deep learning models, it is hard to capture all the variations of the language that different users can use. |
| Approach: | They propose a framework that uses four active learning strategies to identify important samples coming from new users and a self training phase where a teacher model is trained from the first phase to expand the training data with relevant cohort utterances. |
| Outcome: | The proposed framework reduces the bias related to new customers in a digital voice assistant system by using two phases: a fixing phase and a self training phase. |
