Federated One-Shot Learning with Data Privacy and Objective-Hiding

Rüdiger Urbanke

Privacy in federated learning is crucial, encompassing two key aspects: safeguarding the privacy of clients' data and maintaining the privacy of the federator's objective from the clients. While the first aspect has been extensively studied, the second has ...

Analysis of Coupled Scalar Systems by Displacement Convexity

Rüdiger Urbanke, Nicolas Macris, Rafah El-Khatib

Potential functionals have been introduced recently as an important tool for the analysis of coupled scalar systems (e.g. density evolution equations). In this contribution we investigate interesting properties of this potential. Using the tool of displace ...

On the dependency between the code symmetries and the decoding efficiency

Rüdiger Urbanke, Kirill Ivanov

A framework of monomial codes is considered, which includes linear codes generated by the evaluation of certain monomials. Polar and Reed-Muller codes are the two best-known representatives of such codes and can be considered as two extreme cases. Reed-Mul ...

Polar Codes: Robustness of the Successive Cancellation Decoder with Respect to Quantization

Rüdiger Urbanke, Seyed Hamed Hassani

Polar codes provably achieve the capacity of a wide array of channels under successive decoding. This assumes infinite precision arithmetic. Given the successive nature of the decoding algorithm, one might worry about the sensitivity of the performance to ...

High Symbol Rate Coherent Optical Transmission Systems: 80 and 107 Gbaud

Luis Salamanca Miño, Rüdiger Urbanke

We demonstrate high speed optical transmission systems using digital coherent detection at all-electronically multiplexed symbol rates of 80 and 107 Gbaud. At 107 Gbaud, we demonstrate a single-carrier polarization division multiplexed quadrature phase shi ...

The Least Degraded and the Least Upgraded Channel with respect to a Channel Family

Rüdiger Urbanke, Seyed Hamed Hassani, Wei Liu, Wei Liu

Given a family of binary-input memoryless output-symmetric (BMS) channels having a fixed capacity, we derive the BMS channel having the highest (resp.lowest) capacity among all channels that are degraded (resp. upgraded) with respect to the whole family. W ...

A mobile world of security

Rüdiger Urbanke, Christina Fragouli, Panagiotis Papadimitratos, Christine Neuberg

We propose a novel approach to establish crypto- graphic keys among mobile users and a networking infrastruc- ture. Our approach comes at a low cost and can either be used as an alternative to existing solutions or can be employed in a complementary way. O ...
