Papers with average segmentation error
Segmenting Numerical Substitution Ciphers (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for deciphering historical substitution ciphers are difficult to crack . cipheries that are not segmented are still difficult to deciphere . |
| Approach: | They propose automatic methods to segment historical substitution ciphers using BPE and unigram language models. |
| Outcome: | The proposed methods achieve an average segmentation error of 2% on 100 monoalphabetic ciphers and 27% on 3 real historical homophonic cipheries. |
