Detection of cheating by decimation algorithm
Shogo Yamanaka, Masayuki Ohzeki, Aurelien Decelle
We expand the item response theory to study the case of "cheating students" for a set of exams, trying to detect them by applying a greedy algorithm of inference. This extended mod…

High-precision phase diagram of spin glasses from duality analysis with real-space renormalization and graph polynomials
Masayuki Ohzeki, Jesper Lykke Jacobsen
We propose a duality analysis for obtaining the critical manifold of two-dimensional spin glasses. Our method is based on the computation of quenched free energies with periodic an…
