Partitioned List Decoding of Polar Codes: Analysis and Improvement of Finite Length Performance
Seyyed Ali Hashemi, Marco Mondelli, S. Hamed Hassani +2
Polar codes represent one of the major recent breakthroughs in coding theory and, because of their attractive features, they have been selected for the incoming 5G standard. As suc…
Learning to Use Learners' Advice
Adish Singla, Hamed Hassani, Andreas Krause
In this paper, we study a variant of the framework of online learning using expert advice with limited/bandit feedback. We consider each expert as a learning entity, seeking to mor…
Capacity-Achieving Rate-Compatible Polar Codes for General Channels
Marco Mondelli, S. Hamed Hassani, Ivana Marić +2
We present a rate-compatible polar coding scheme that achieves the capacity of any family of channels. Our solution generalizes the previous results [1], [2] that provide capacity-…
Near-optimal Bayesian Active Learning with Correlated and Noisy Tests
Yuxin Chen, S. Hamed Hassani, Andreas Krause
We consider the Bayesian active learning and experimental design problem, where the goal is to learn the value of some unknown target variable through a sequence of informative, no…
Unified Scaling of Polar Codes: Error Exponent, Scaling Exponent, Moderate Deviations, and Error Floors
Marco Mondelli, S. Hamed Hassani, Rüdiger Urbanke
Consider the transmission of a polar code of block length and rate over a binary memoryless symmetric channel and let be the block error probability under success…
Alignment of Polarized Sets
Joseph M. Renes, David Sutter, S. Hamed Hassani
Arıkan's polar coding technique is based on the idea of synthesizing channels from the instances of the physical channel by a simple linear encoding transformation. Each sy…
