Weak detection in the spiked Wigner model
Hye Won Chung, Ji Oon Lee
We consider the weak detection problem in a rank-one spiked Wigner data matrix where the signal-to-noise ratio is small so that reliable detection is impossible. We propose a hypot…

Parity Queries for Binary Classification
Hye Won Chung, Ji Oon Lee, Doyeon Kim +1
Consider a query-based data acquisition problem that aims to recover the values of binary variables from parity (XOR) measurements of chosen subsets of the variables. Assume th…

Fundamental Limits on Data Acquisition: Trade-offs between Sample Complexity and Query Difficulty
Hye Won Chung, Ji Oon Lee, Alfred O. Hero
We consider query-based data acquisition and the corresponding information recovery problem, where the goal is to recover binary variables (information bits) from parity measur…
