Unsupervised learning of phase transitions: from principal component analysis to variational autoencoderscond-mat.stat-mech

We employ unsupervised machine learning techniques to learn latent parameters which best describe states of the two-dimensional Ising model and the three-dimensional XY model. These methods range from principal component analysis to artificial neural network based variational autoencoders. The states are sampled using …
