Class Imbalance in Anomaly Detection: Learning from an Exactly Solvable Model
F. S. Pezzicoli, V. Ros, F. P. Landes +1
Class imbalance (CI) is a longstanding problem in machine learning, slowing down training and reducing performances. Although empirical remedies exist, it is often unclear which on…
Memory and rejuvenation in spin glasses: aging systems are ruled by more than one length scale
Janus Collaboration, M. Baity-Jesi, E. Calore +22
Memory and rejuvenation effects in the magnetic response of off-equilibrium spin glasses have been widely regarded as the doorway into the experimental exploration of ultrametricit…
Inherent Structures in m-component Spin Glasses
M. Baity-Jesi, G. Parisi
We observe numerically the properties of the infinite-temperature inherent structures of m-component vector spin glasses in three dimensions. An increase of m implies a decrease of…
The three dimensional Ising spin glass in an external magnetic field: the role of the silent majority
Janus Collaboration, M. Baity-Jesi, R. A. Banos +22
We perform equilibrium parallel-tempering simulations of the 3D Ising Edwards-Anderson spin glass in a field. A traditional analysis shows no signs of a phase transition. Yet, we e…
Phase Transition in 3d Heisenberg Spin Glasses with Strong Random Anisotropies, through a Multi-GPU Parallelization
M. Baity-Jesi, L. A. Fernandez, V. Martin-Mayor +1
We characterize the phase diagram of anisotropic Heisenberg spin glasses, finding both the spin and the chiral glass transition. We remark the presence of strong finite-size effect…
Dynamical transition in the D = 3 Edwards-Anderson spin glass in an external magnetic field
Janus Collaboration, M. Baity-Jesi, R. Alvarez Baños +22
We study the off-equilibrium dynamics of the three-dimensional Ising spin glass in the presence of an external magnetic field. We have performed simulations both at fixed temperatu…
Reconfigurable computing for Monte Carlo simulations: results and prospects of the Janus project
Janus Collaboration, M. Baity-Jesi, R. A. Banos +24
We describe Janus, a massively parallel FPGA-based computer optimized for the simulation of spin glasses, theoretical models for the behavior of glassy materials. FPGAs (as compare…
