Fast Channel Simulation via Error-Correcting Codes

Sharang M. Sriramu, Rochelle Barsz, Elizabeth Polito, Aaron B. Wagner

NeurIPS 2024poster

We consider the design of practically-implementable schemes for the task of channel simulation. Existing methods do not scale with the number of simultaneous uses of the channel and are therefore unable to harness the amortization gains associated with simulating many uses of the channel at once. W…

Principal Bit Analysis: Autoencoding with Schur-Concave Loss

Sourbh Bhadane, Aaron B Wagner, Jayadev Acharya

ICML 2021spotlight

We consider a linear autoencoder in which the latent variables are quantized, or corrupted by noise, and the constraint is Schur-concave in the set of latent variances. Although finding the optimal encoder/decoder pair for this setup is a nonconvex optimization problem, we show that decomposing the…
