Papers with cross-lingual model
AdvPicker: Effectively Leveraging Unlabeled Data via Adversarial Discriminator for Cross-Lingual NER (2021.acl-long)
Copied to clipboard
| Challenge: | Named entity recognition models rely on expensive labeled data for training, which is not always available across languages. |
| Approach: | They propose an adversarial approach where an encoder learns entity domain knowledge from labeled source-language data and better shared features are captured via adversarially trained discriminators. |
| Outcome: | The proposed approach outperforms existing state-of-the-art methods on standard benchmark datasets and outperformed existing methods on the target language. |

| Challenge: | Complex Word Identification (CWI) is the task of identifying which words or phrases in a sentence are difficult to understand by a specific type of reader. |
| Approach: | They propose to use monolingual and cross-lingual CWI models to make predictions for languages not seen during training. |
| Outcome: | The proposed models perform as well as (or better than) most models submitted to the latest CWI Shared Task. |
Parallel Data Helps Neural Entity Coreference Resolution (2023.findings-acl)
Copied to clipboard
| Challenge: | Current neural coreference models are trained on monolingual annotated data but annotating such coreference information is expensive and challenging. |
| Approach: | They propose a simple yet effective model to exploit coreference knowledge from parallel data. |
| Outcome: | The proposed model improves on the OntoNotes 5.0 English dataset by 1.74 percentage points . it is based on an unsupervised module learning coreference from annotations . |
Masked Language Model Scoring (2020.acl-main)
Copied to clipboard
| Challenge: | Pretrained masked language models require finetuning for most tasks. |
| Approach: | They evaluate pretrained masked language models out of the box via their pseudo-log-likelihood scores (PLLs) they attribute this success to PLL’s unsupervised expression of linguistic acceptability without a left-to-right bias, greatly improving on scores from GPT-2 . |
| Outcome: | The proposed model outperforms autoregressive language models in a variety of tasks. |
GradSim: Gradient-Based Language Grouping for Effective Multilingual Training (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing studies show that not all languages positively influence each other . multilingual training can help in those cases by sharing knowledge across languages . |
| Approach: | They propose a gradient similarity-based language grouping method for multilingual training that is better correlated with cross-lingual model performance. |
| Outcome: | The proposed method leads to the largest performance gains on a multilingual dataset and is better correlated with cross-lingual model performance. |
Hybrid Knowledge Transfer for Improved Cross-Lingual Event Detection via Hierarchical Sample Selection (2023.acl-long)
Copied to clipboard
| Challenge: | Recent efforts to train cross-lingual models on source language fail to take advantage of data transfer . current methods focus on learning task-specific information from syntactical features or word-label relations in target language. |
| Approach: | They propose a hybrid knowledge-transfer approach that leverages a teacher-student framework . the model is evaluated on a distinct target language for which there is no labeled data . |
| Outcome: | The proposed model achieves state-of-the-art results on 9 morphologically-diverse target languages across 3 distinct datasets. |
VECO: Variable and Flexible Cross-lingual Pre-training for Language Understanding and Generation (2021.acl-long)
Copied to clipboard
| Challenge: | Existing work in multilingual pretraining relies on the shared vocabulary and bilingual contexts to encourage the correlation across languages. |
| Approach: | They propose to plug a cross-attention module into a Transformer encoder to explicitly build the interdependence between languages. |
| Outcome: | The proposed model outperforms existing models on XTREME and English-to-French translation datasets. |
Detecting Languages Unintelligible to Multilingual Models through Local Structure Probes (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Recent advances in multilingual pretrained models have proven effective at zero-shot transfer to a wide variety of languages, but this transfer is not universal, with many languages not currently understood by multilingual approaches. |
| Approach: | They propose a general approach that requires only unlabelled text to detect which languages are not well understood by a cross-lingual model. |
| Outcome: | The proposed model can detect which languages are not well understood by a multilingual model on 350 low-resource languages. |
Data Augmentation with Adversarial Training for Cross-Lingual NLI (2021.acl-long)
Copied to clipboard
| Challenge: | Existing approaches to train cross-lingual models with labeled data are subpar, resulting in subpar results. |
| Approach: | They propose a data augmentation strategy that enriches data to reflect more diversity in a semantically faithful way and leverages adversarial training regimens to achieve greater robustness. |
| Outcome: | The proposed approach improves cross-lingual inference by leveraging the data to reflect more diversity in a semantically faithful way. |
Macedon: Minimizing Representation Coding Rate Reduction for Cross-Lingual Natural Language Understanding (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Existing approaches to learn cross-lingual models require limited data to perform cross-linguistic tasks. |
| Approach: | They propose a method to remove language-associated information via minimizing representation coding rate reduction. |
| Outcome: | The proposed model outperforms state-of-the-art models on cross-lingual tasks. |
