Partner-Aware Algorithms in Decentralized Cooperative Bandit Teams

no code implementations2 Oct 2021 Erdem Biyik, Anusha Lalitha, Rajarshi Saha, Andrea Goldsmith, Dorsa Sadigh

Our results show that the proposed partner-aware strategy outperforms other known methods, and our human subject studies suggest humans prefer to collaborate with AI agents implementing our partner-aware strategy.

Parallelism versus Latency in Simplified Successive-Cancellation Decoding of Polar Codes

no code implementations24 Dec 2020 Seyyed Ali Hashemi, Marco Mondelli, Arman Fazeli, Alexander Vardy, John Cioffi, Andrea Goldsmith

In particular, when the number of processing elements $P$ that can perform SSC decoding operations in parallel is limited, as is the case in practice, the latency of SSC decoding is $O\left(N^{1-1/\mu}+\frac{N}{P}\log_2\log_2\frac{N}{P}\right)$, where $N$ is the block length of the code and $\mu$ is the scaling exponent of the channel.

Bayesian Algorithms for Decentralized Stochastic Bandits

no code implementations20 Oct 2020 Anusha Lalitha, Andrea Goldsmith

Specifically, we study an information assimilation algorithm that can be combined with existing Bayesian algorithms, and using this, we propose a decentralized Thompson Sampling algorithm and decentralized Bayes-UCB algorithm.

We consider the problem of joint source and channel coding of structured data such as natural language over a noisy channel.

Neural Network Detection of Data Sequences in Communication Systems

no code implementations31 Jan 2018 Nariman Farsad, Andrea Goldsmith

We consider detection based on deep learning, and show it is possible to train detectors that perform well without any knowledge of the underlying channel models.

Detection Algorithms for Communication Systems Using Deep Learning

no code implementations22 May 2017 Nariman Farsad, Andrea Goldsmith

The design and analysis of communication systems typically rely on the development of mathematical models that describe the underlying communication channel, which dictates the relationship between the transmitted and the received signals.
