This tutorial shows how to find descriptive parameters (short formulas) for the prediction of
topological phase transitions. As an example, we address the topological classification of
two-dimensional functionalized honeycomb-lattice materials, which are formally described by
- the $Z_2$ topological invariant, i.e., $Z_2=0$ for trivial (normal) insulators and $Z_2=1$ for two-dimensional
+ the Z2 topological invariant, i.e., Z2=0 for trivial (normal) insulators and Z2=1 for two-dimensional
topological insulators (quantum spin Hall insulators).
Using a recently developed machine learning based on compressed sensing, we then derive a map of
these materials, in which metals, trivial insulators, and quantum spin Hall insulators are separated
