Query: Phase diagram of disordered higher-order topological insulator: A
  machine learning study   A higher-order topological insulator is a new concept of topological states
of matter, which is characterized by the emergent boundary states whose
dimensionality is lower by more than two compared with that of the bulk, and
draws a considerable interest. Yet, its robustness against disorders is still
unclear. Here we investigate a phase diagram of higher-order topological
insulator phases in a breathing kagome model in the presence of disorders, by
using a state-of-the-art machine learning technique. We find that the corner
states survive against the finite strength of disorder potential as long as the
energy gap is not closed, indicating the stability of the higher-order
topological phases against the disorders.
