Papers with multi-task architecture
LATEX-Numeric: Language Agnostic Text Attribute Extraction for Numeric Attributes (2021.naacl-industry)
Copied to clipboard
| Challenge: | Existing methods for training numeric attributes are based on manual labeling and distant supervision leads to incomplete training annotations. |
| Approach: | They propose a multi-task learning architecture to deal with missing attribute values in training data, removing dependency on manual annotations. |
| Outcome: | The proposed framework improves on 20 numeric attributes extracted from 5 product categories and 3 english marketplaces with language-agnostic performance. |
Exploiting Entity BIO Tag Embeddings and Multi-task Learning for Relation Extraction with Imbalanced Data (P19-1)
Copied to clipboard
| Challenge: | Existing methods to perform relation extraction are feature-based or kernel-based, but the results of our study show that they can improve the performance of a baseline model with more than 10% absolute increase in F1-score. |
| Approach: | They propose a multi-task architecture which jointly trains a model to perform relation identification with cross-entropy loss and relation classification with ranking loss. |
| Outcome: | The proposed model outperforms the state-of-the-art models on ACE 2005 Chinese and English corpus and significantly improves the performance of a baseline model with more than 10% increase in F1-score. |
HSCNN: A Hybrid-Siamese Convolutional Neural Network for Extremely Imbalanced Multi-label Text Classification (2020.emnlp-main)
Copied to clipboard
| Challenge: | Existing approaches to solve the data imbalance problem are limited in extremely imbalanced data. |
| Approach: | They propose a hybrid approach which adapts general networks for head categories and few-shot techniques for tail categories. |
| Outcome: | The proposed approach improves the performance of Single networks with diverse loss objectives on tail or entire categories. |
