DeFT-X: Denoised Sparse Fine-Tuning for Zero-Shot Cross-Lingual Transfer (2025.findings-emnlp)

Copied to clipboard

Challenge: Prior studies have explored multiple approaches to combine task knowledge from task-specific data in a (high-resource) source language with language knowledge from unlabeled text in 'low-resourced' target language.
Approach: They propose a composable sparse fine-tuning approach that learns task-specific and language-specific sparsen masks to select a subset of the pretrained model's parameters.
Outcome: The proposed approach performs at par or outperforms SFT and other prominent cross-lingual transfer baselines.
Composable Sparse Fine-Tuning for Cross-Lingual Transfer (2022.acl-long)

Copied to clipboard

Challenge: Adapters and sparse fine-tuning have been developed to improve transfer learning . a number of approaches have been proposed to improve performance of fine-untuners .
Approach: They propose a method that fine-tunes the entire set of parameters of a large pretrained model . they use adapters and sparse fine-uning to improve model efficiency .
Outcome: The proposed method outperforms adapters in cross-lingual transfer benchmarks.
Unifying Cross-Lingual Transfer across Scenarios of Resource Scarcity (2023.emnlp-main)

Copied to clipboard

Challenge: Existing approaches to deal with resource scarcity have not been developed to deal effectively with the problem.
Approach: They propose to use a set of tools to harness data from one or more high-resource "source" languages to compensate for a shortage of data in low-resourced "target" languages.
Outcome: The proposed technique can be easily adapted to unseen languages, extending the range of the proposed technique and translation-based transfer more broadly.
AmericasNLI: Evaluating Zero-shot Natural Language Understanding of Pretrained Multilingual Models in Truly Low-resource Languages (2022.acl-long)

Copied to clipboard

Challenge: Pretrained multilingual models can perform cross-lingual transfer in a zero-shot setting, even for unseen languages.
Approach: They propose to extend XNLI to 10 indigenous languages of the Americas and test multiple zero-shot and translation-based approaches.
Outcome: The proposed model can perform cross-lingual transfer in a zero-shot setting even for languages unseen during pretraining.
