| Challenge: | obfuscation-by-transfer is a method of obliging writing style using sequence models . a side effect of this approach is the frequent major alterations to the semantic content of the input . |
| Approach: | They propose obfuscation-by-invariance and investigate to what extent models trained to be explicitly style-independent preserve semantics. |
| Outcome: | The proposed model performs better than models trained to be explicitly style-invariant, while human evaluation shows a trade-off between the level of obfuscation and the quality of the output. |
