Papers with feature augmentation
Integrating Semantic Knowledge to Tackle Zero-shot Text Classification (N19-1)
Copied to clipboard
| Challenge: | Existing approaches to classify text documents of emerging classes are ineffective because of insufficient or even unavailable training data. |
| Approach: | They propose a two-phase framework with data augmentation and feature augmentation to deal with unseen classes effectively using four kinds of semantic knowledge. |
| Outcome: | The proposed framework achieves the best overall accuracy compared with baselines and recent approaches in classifying real-world texts under the zero-shot scenario. |
Semi-supervised Domain Adaptation for Dependency Parsing via Improved Contextualized Word Representations (2020.coling-main)
Copied to clipboard
| Challenge: | Recent advances in deep neural network models have improved parsing performance on in-domain texts . however, the problem is to improve performance on out-of-domain text data when there is only a small-scale out-domain labeled data. |
| Approach: | They propose to use adversarial learning and fine-tuning BERT to improve contextualized word representations on out-of-domain texts. |
| Outcome: | The proposed models achieve consistent improvement and fine-tune BERT processes boost parsing accuracy by a large margin. |
AccentDB: A Database of Non-Native English Accents to Assist Neural Speech Recognition (2020.lrec-1)
Copied to clipboard
| Challenge: | aaron e. sanchez and joe saunders: automatic speech recognition still faces a major challenge . they say accents are a way of pronouncing a language, and speakers always have manner of speaking . esassen: accents can be used to identify non-native speakers of a speech . |
| Approach: | They propose to create a database of speech samples in non-native accents for ASR testing . they also propose to introduce accent neutralization of non- native accents to native accent . |
| Outcome: | The proposed model is compared against human-labelled accent classes and is generalized against human data. |
