Charging and Discharging a Hubbard-Holstein Quantum Battery: Specific Mechanisms and General Insights
Emil Östberg, Arvid Steen, Najmeh Abiri +2
A Hubbard-Holstein dimer functions as a correlation-driven quantum battery, with ergotropy robustly stored, under some conditions, even in the presence of dissipation. We find that…
Latent Space Score-based Diffusion Model for Probabilistic Multivariate Time Series Imputation
Guojun Liang, Najmeh Abiri, Atiye Sadat Hashemi +3
Accurate imputation is essential for the reliability and success of downstream tasks. Recently, diffusion models have attracted great attention in this field. However, these models…
Establishing strong imputation performance of a denoising autoencoder in a wide range of missing data problems
Najmeh Abiri, Björn Linse, Patrik Edén +1
Dealing with missing data in data analysis is inevitable. Although powerful imputation methods that address this problem exist, there is still much room for improvement. In this st…
Variational auto-encoders with Student's t-prior
Najmeh Abiri, Mattias Ohlsson
We propose a new structure for the variational auto-encoders (VAEs) prior, with the weakly informative multivariate Student's t-distribution. In the proposed model all distribution…
