urn:hdl:2445/195455 Supervised learning of few dirty bosons with variable particle number Mujal Torreblanca, Pere Martínez Miguel, Alex Polls Martí, Artur Juliá-Díaz, Bruno Pilati, Sebastiano Bosons Física de partícules Teoria quàntica Bosons Particle physics Quantum theory We investigate the supervised machine learning of few interacting bosons in optical speckle disorder via artificial neural networks. The learning curve shows an approximately universal power-law scaling for different particle numbers and for different interaction strengths. We introduce a network architecture that can be trained and tested on heterogeneous datasets including different particle numbers. This network provides accurate predictions for all system sizes included in the training set and, by design, is suitable to attempt extrapolations to (computationally challenging) larger sizes. Notably, a novel transfer-learning strategy is implemented, whereby the learning of the larger systems is substantially accelerated and made consistently accurate by including in the training set many small-size instances. 2023-03-17T15:52:01Z 2023-03-17T15:52:01Z 2021-03-24 2023-03-17T15:52:01Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.21468/SciPostPhys.10.3.073 SciPost Physics, 2021, vol. 10, num. 3, p. 73-89 https://doi.org/10.21468/SciPostPhys.10.3.073 cc-by (c) Mujal Torreblanca, Pere et al., 2021 https://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess SciPost Foundation Articles publicats en revistes (Física Quàntica i Astrofísica)
