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…
Free energy of bipartite spherical Sherrington--Kirkpatrick model
Jinho Baik, Ji Oon Lee
We consider the free energy of the bipartite spherical Sherrington--Kirkpatrick model. We find the critical temperature and prove the limiting free energy for all non-critical temp…
Local law and Tracy-Widom limit for sparse random matrices
Ji Oon Lee, Kevin Schnelli
We consider spectral properties and the edge universality of sparse random matrices, the class of random matrices that includes the adjacency matrices of the Erdos-Renyi graph mode…
Ground State Energy of Dilute Bose Gas in Small Negative Potential Case
Ji Oon Lee
It is well known that the ground state energy of a three dimensional dilute Bose gas in the thermodynamic limit is when the particles interact via a non-negative, finite…
