Label-guided Learning for Text Classification [article]

Xien Liu, Song Wang, Xiao Zhang, Xinxin You, Ji Wu, Dejing Dou
2020 arXiv   pre-print
Text classification is one of the most important and fundamental tasks in natural language processing. Performance of this task mainly dependents on text representation learning.  ...  That label-guided layer performs label-based attentive encoding to map the universal text embedding (encoded by a contextual information learner) into different label spaces, resulting in label-wise embeddings  ...  All of these text learning methods are based on modeling local contextual information between words to encode a piece of text into a universal embedding, without considering the difference of labels.  ...

Guiding Generative Language Models for Data Augmentation in Few-Shot Text Classification [article]

Aleksandra Edwards, Asahi Ushio, Jose Camacho-Collados, Hélène de Ribaupierre, Alun Preece
2021 arXiv   pre-print
Our aim is to analyse the impact the selection process of seed training examples have over the quality of GPT-generated samples and consequently the classifier performance.  ...  Our results show that fine-tuning GPT-2 in a handful of label instances leads to consistent classification improvements and outperform competitive baselines.  ...  Therefore, our aim is to improve the quality of generated artificial instances and thus improve classifiers by developing seed selection strategies to guide the generation process.  ...

Topic-Guided Abstractive Text Summarization: a Joint Learning Approach [article]

Chujie Zheng, Kunpeng Zhang, Harry Jiannan Wang, Ling Fan, Zhe Wang
2021 arXiv   pre-print
We introduce a new approach for abstractive text summarization, Topic-Guided Abstractive Summarization, which calibrates long-range dependencies from topic-level features with globally salient content.  ...  The idea is to incorporate neural topic modeling with a Transformer-based sequence-to-sequence (seq2seq) model in a joint learning framework.  ...  For text summarization, by incorporating the topic-level features into the summarization model, we believe it can improve model performance since it encourages the model to focus on both local relationships  ...
