SoftBinary Coding: A New Information-Theoretic Neural Compression Paradigm
Ezgi Ozyilkan, Sharang M. Sriramu, Elza Erkip +2
Neural compression is currently dominated by Nonlinear Transform Coding (NTC), which maps data to real-valued latents via continuous transforms. Despite its success, NTC suffers fr…
Exact Redundancy for Symmetric Rate-Distortion
Sharang M. Sriramu, Aaron B. Wagner
For variable-length coding with an almost-sure distortion constraint, Zhang et al. show that for discrete sources the redundancy is upper bounded by and lower bounded (i…
The Redundancy of Non-Singular Channel Simulation
Gergely Flamich, Sharang M. Sriramu, Aaron B. Wagner
Channel simulation is an alternative to quantization and entropy coding for performing lossy source coding. Recently, channel simulation has gained significant traction in both the…
Optimal Redundancy in Exact Channel Synthesis
Sharang M. Sriramu, Aaron B. Wagner
We consider the redundancy of the exact channel synthesis problem under an i.i.d. assumption. Existing results provide an upper bound on the unnormalized redundancy that is logarit…
