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.,
Z
2=0 for trivial (normal) insulators and
Z
2=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
