Unified Description of Learning Dynamics in the Soft Committee Machine from Finite to Ultra-Wide Regimes
Assem Afanah, Bernd Rosenow
We study the learning dynamics of the soft committee machine (SCM) with Rectified Linear Unit (ReLU) activation using a statistical-mechanics approach within the annealed approxima…
BBP Phase Transition for an Extensive Number of Outliers
Niklas Forner, Alexander Maloney, Bernd Rosenow
Random-matrix theory helps disentangle signal from noise in large data sets. We analyze rectangular matrices in which the noise generates a Marchenko…
Edge Reconstruction in a Quantum Spin Hall Insulator
Rahul Soni, Matthias Thamm, Gonzalo Alvarez +2
We study interaction-driven edge reconstruction in a quantum spin Hall insulator described by the Bernevig-Hughes-Zhang model with Kanamori-Hubbard interactions using the real-spac…
Berezinskii-Kosterlitz-Thouless Renormalization Group Flow at a Quantum Phase Transition
Matthias Thamm, Harini Radhakrishnan, Hatem Barghathi +4
We present a controlled numerical study of the Berezinskii-Kosterlitz-Thouless (BKT) transition in the one-dimensional Bose-Hubbard model at unit filling, providing evidence of the…
