Soft GRAND under Channel Uncertainty: Minimax Posterior-Envelope Ordering and Gallager-Exponent Preservation
Behrooz Razeghi
Soft Guessing Random Additive Noise Decoding queries corrections in an observation-dependent order. For a known channel, the matched order ranks corrections by nonincreasing condit…
Soft GRAND under Channel Switching and Drift
Behrooz Razeghi
Under channel switching or drift, the posterior used to order Guessing Random Additive Noise Decoding (GRAND) queries can differ from the matched correction posterior, increasing q…
Tail-Calibrated Soft-Output GRAND for Finite-Memory Noise-Effect Posteriors
Behrooz Razeghi
In guessing random additive noise decoding (GRAND), memory in the hard-decision noise effect changes the likelihood order of candidate noise effects. In soft-output decoding, the s…
Low-Pathwidth GRAND: Exact Likelihood-Ordered Enumeration for BPSK Transmission over Correlated Gaussian Noise
Behrooz Razeghi
The finite-block maximum-likelihood (ML) guarantee of soft-input GRAND requires querying noise-effect patterns in nonincreasing conditional-likelihood order. Under correlated Gauss…
On the Capacity of Distinguishable Synthetic Identity Generation under Face Verification
Behrooz Razeghi
Synthetic face generators can produce many nominal identities, but nominal count does not determine how many are jointly distinguishable under a specified verification rule. We def…
On Perfect Obfuscation: Local Information Geometry Analysis
Behrooz Razeghi, Flavio. P. Calmon, Deniz Gunduz +1
We consider the problem of privacy-preserving data release for a specific utility task under perfect obfuscation constraint. We establish the necessary and sufficient condition to…
