Improving Privacy Guarantee and Efficiency of Latent Dirichlet Allocation Model Training Under Differential Privacy (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Latent Dirichlet allocation (LDA) is a widely used topic model to discover the latent semantic of text data. |
| Approach: | They propose to combine a subsampling method with CGS to improve efficiency while amplifying privacy by using a novel metric, the efficiency–privacy function. |
| Outcome: | The proposed algorithm improves efficiency while amplifying privacy while subsampling in CGS increases efficiency while preserving privacy. |
