Can Public Large Language Models Help Private Cross-device Federated Learning? (2024.findings-naacl)
Copied to clipboard
| Challenge: | Recent studies have shown that public data can be used to improve privacy-utility trade-offs for large and small language models. |
| Approach: | They propose to use large-scale public data to help differentially private FL training . they propose a distribution matching algorithm with theoretical grounding to sample public data close to private data distribution . |
| Outcome: | The proposed method is efficient and effective for training private models by taking advantage of public data. |
Better Alignment with Instruction Back-and-Forth Translation (2024.findings-emnlp)
Copied to clipboard
| Challenge: | et al., 2023) proposes a method to improve instruction-tuning data . e.g., we generate synthetic instructions using the backtranslation approach . |
| Approach: | They propose a method to improve instruction-tuning data using web-based inputs . they generate synthetic instructions using the backtranslation approach and filter the generated data . |
| Outcome: | The proposed method improves the quality of instruction-tuning data based on preprocessed texts . it yields better AlpacaEval win rates than direct distillation . |
