DoDo-Code: a Deep Levenshtein Distance Embedding-based Code for IDS Channel and DNA Storage

no code implementations20 Dec 2023 Alan J. X. Guo, Sihan Sun, Xiang Wei, Mengyi Wei, Xin Chen

In this paper, we propose an innovative approach that utilizes deep Levenshtein distance embedding to bypass these mathematical challenges.

Levenshtein Distance Embedding with Poisson Regression for DNA Storage

no code implementations13 Dec 2023 Xiang Wei, Alan J. X. Guo, Sihan Sun, Mengyi Wei, Wei Yu

Under this embedding dimension, the Poisson regression is introduced by assuming the Levenshtein distance between sequences of fixed length following a Poisson distribution, which naturally aligns with the definition of Levenshtein distance.
