Marker-Delimited Codes for Short-Blocklength, High-Rate Coding over Multi-Read Edit Channels
Sinan Ates Yercan, Marc Antonini, Serge Kas Hanna
The read process of DNA-based data storage systems generates multiple noisy copies of the stored DNA sequences, affected by edit errors consisting of substitutions, deletions, and…
The Synthesis-Sequencing Channel for DNA-based Data Storage
Keshav Goyal, Samuel Pearson, João Ribeiro +1
We introduce and study the synthesis-sequencing channel, a two-stage model for DNA-based data storage that jointly captures synthesis and sequencing effects. The synthesis-sequenci…
DNA-MGC+: A versatile codec for reliable and resource-efficient data storage on synthetic DNA
Ramy Khabbaz, Jérémy Mateos, Marc Antonini +1
The biochemical processes underlying DNA data storage, including synthesis, amplification, and sequencing, are inherently noisy. Consequently, base-level insertion, deletion, and s…
On the Reliability of Information Retrieval From MDS Coded Data in DNA Storage
Serge Kas Hanna
This work presents a theoretical analysis of the probability of successfully retrieving data encoded with MDS codes (e.g., Reed-Solomon codes) in DNA storage systems. We study this…
Approximate Gradient Coding for Privacy-Flexible Federated Learning with Non-IID Data
Okko Makkonen, Sampo Niemelä, Camilla Hollanti +1
This work focuses on the challenges of non-IID data and stragglers/dropouts in federated learning. We introduce and explore a privacy-flexible paradigm that models parts of the cli…
GC+ Code: A Systematic Short Blocklength Code for Correcting Random Edit Errors in DNA Storage
Serge Kas Hanna
Storing digital data in synthetic DNA faces challenges in ensuring data reliability in the presence of edit errors--deletions, insertions, and substitutions--that occur randomly du…
