Polar Codes Do Not Have Many Affine Automorphisms

Kirill Ivanov, Rüdiger Urbanke

Polar coding solutions demonstrate excellent performance under the list decoding that is challenging to implement in hardware due to the path sorting operations. As a potential sol…

Noether: The More Things Change, the More Stay the Same

Grzegorz Głuch, Rüdiger Urbanke

Symmetries have proven to be important ingredients in the analysis of neural networks. So far their use has mostly been implicit or seemingly coincidental. We undertake a systemati…

On the efficiency of polar-like decoding for symmetric codes

Kirill Ivanov, Rüdiger Urbanke

The recently introduced polar codes constitute a breakthrough in coding theory due to their capacityachieving property. This goes hand in hand with a quasilinear construction, enco…

Adversarial Robustness: What fools you makes you stronger

Grzegorz Głuch, Rüdiger Urbanke

We prove an exponential separation for the sample complexity between the standard PAC-learning model and a version of the Equivalence-Query-learning model. We then show that this s…

Capacity-achieving codes: a review on double transitivity

Kirill Ivanov, Rüdiger L. Urbanke

Recently it was proved that if a linear code is invariant under the action of a doubly transitive permutation group, it achieves the capacity of erasure channel. Therefore, it is o…

Query complexity of adversarial attacks

Grzegorz Głuch, Rüdiger Urbanke

There are two main attack models considered in the adversarial robustness literature: black-box and white-box. We consider these threat models as two ends of a fine-grained spectru…
