Machine-Learned Phase Diagrams of Generalized Kitaev Honeycomb Magnets

1 code implementation1 Feb 2021 Nihal Rao, Ke Liu, Marc Machaczek, Lode Pollet

We use a recently developed interpretable and unsupervised machine-learning method, the tensorial kernel support vector machine (TK-SVM), to investigate the low-temperature classical phase diagram of a generalized Heisenberg-Kitaev-$\Gamma$ ($J$-$K$-$\Gamma$) model on a honeycomb lattice.

Learning multiple order parameters with interpretable machines

2 code implementations11 Oct 2018 Ke Liu, Jonas Greitemann, Lode Pollet

Furthermore, we discuss an intrinsic parameter of SVM, the bias, which allows for a special interpretation in the classification of phases, and its utility in diagnosing the existence of phase transitions.
