Counterfactual Explanation for Auto-Encoder Based Time-Series Anomaly Detection
Abhishek Srinivasan, Varun Singapuri Ravi, Juan Carlos Andresen +1
The complexity of modern electro-mechanical systems require the development of sophisticated diagnostic methods like anomaly detection capable of detecting deviations. Conventional…
Ensemble Neural Networks for Remaining Useful Life (RUL) Prediction
Ahbishek Srinivasan, Juan Carlos Andresen, Anders Holst
A core part of maintenance planning is a monitoring system that provides a good prognosis on health and degradation, often expressed as remaining useful life (RUL). Most of the cur…
Modular Federated Learning
Kuo-Yun Liang, Abhishek Srinivasan, Juan Carlos Andresen
Federated learning is an approach to train machine learning models on the edge of the networks, as close as possible where the data is produced, motivated by the emerging problem o…
The Effect of Intrinsic Quantum Fluctuations on the Phase Diagram of Anisotropic Dipolar Magnets
Tomer Dollberg, Juan Carlos Andresen, Moshe Schechter
The rare-earth material is believed to be an experimental realization of the celebrated (dipolar) Ising model, and upon the inclusion of a transverse field …
Numerical observation of a glassy phase in the three-dimensional Coulomb glass
Amin Barzegar, Juan Carlos Andersen, Moshe Schechter +1
The existence of an equilibrium glassy phase for charges in a disordered potential with long-range electrostatic interactions has remained controversial for many years. Here we con…
Pauling entropy, metastability and equilibrium in DyTiO spin ice
S. R. Giblin, M. Twengström, L. Bovo +17
Determining the fate of the Pauling entropy in the classical spin ice material DyTiO with respect to the third law of thermodynamics has become an important test case f…
Random-field-induced disordering mechanism in a disordered ferromagnet: Between the Imry-Ma and the standard disordering mechanism
Juan Carlos Andresen, Helmut G. Katzgraber, Moshe Schechter
Random fields disorder Ising ferromagnets by aligning single spins in the direction of the random field in three space dimensions, or by flipping large ferromagnetic domains at dim…
Existence of a Thermodynamic Spin-Glass Phase in the Zero-Concentration Limit of Anisotropic Dipolar Systems
Juan Carlos Andresen, Helmut G. Katzgraber, Vadim Oganesyan +1
The nature of ordering in dilute dipolar interacting systems dates back to the work of Debye and is one of the most basic, oldest and as-of-yet unsettled problems in magnetism. Whi…
Boolean decision problems with competing interactions on scale-free networks: Equilibrium and nonequilibrium behavior in an external bias
Zheng Zhu, Juan Carlos Andresen, M. A. Moore +1
We study the equilibrium and nonequilibrium properties of Boolean decision problems with competing interactions on scale-free networks in an external bias (magnetic field). Previou…
Charge avalanches and depinning in the Coulomb glass: The role of long-range interactions
Juan Carlos Andresen, Yohanes Pramudya, Helmut G. Katzgraber +3
We explore the stability of far-from-equilibrium metastable states of a three-dimensional Coulomb glass at zero temperature by studying charge avalanches triggered by a slowly vary…
Self-Organized Criticality in Glassy Spin Systems Requires a Diverging Number of Neighbors
Juan Carlos Andresen, Zheng Zhu, Ruben S. Andrist +3
We investigate the conditions required for general spin systems with frustration and disorder to display self-organized criticality, a property which so far has been established on…
Novel disordering mechanism in ferromagnetic systems with competing interactions
Juan Carlos Andresen, Creighton K. Thomas, Helmut G. Katzgraber +1
Ferromagnetic Ising systems with competing interactions are considered in the presence of a random field. We find that in three space dimensions the ferromagnetic phase is disorder…
Critical behavior and universality in Levy spin glasses
Juan Carlos Andresen, Katharina Janzen, Helmut G. Katzgraber
Using large-scale Monte Carlo simulations that combine parallel tempering with specialized cluster updates, we show that Ising spin glasses with Levy-distributed interactions share…
