The three-dimensional Anderson model is a well-studied model of disordered electron systems that shows the delocalization–localization transition. As in our previous papers on two- and three-dimensional (2D, 3D) quantum phase transitions [ J. Phys. Soc. Jpn. 85 , 123706 (2016) , 86 , 044708 (2017) ], we used an image recognition algorithm based on a multilayered convolutional neural network. However, in contrast to previous papers in which 2D image recognition was used, we applied 3D image recognition to analyze entire 3D wave functions. We show that a full phase diagram of the disorder-energy plane is obtained once the 3D convolutional neural network has been trained at the band center. We further demonstrate that the full phase diagram for 3D quantum bond and site percolations can be... drawn by training the 3D Anderson model at the band center.
