We apply machine learning techniques to solve a specific classification
problem in 4D F-theory. For a divisor $D$ on a given complex threefold base, we
want to read out the non-Higgsable gauge group on it using local geometric
information near $D$. The input features are the triple intersection numbers
among divisors near $D$ and the output label is the non-Higgsable gauge group.
We use decision tree to solve this problem and achieved 85%-98% out-of-sample
accuracies for different classes of divisors, where the data sets are generated
from toric threefold bases without (4,6) curves. We have explicitly generated a
large number of analytic rules directly from the decision tree and proved a
small number of them. As a crosscheck, we applied these decision trees on bases
with (4,6) curves as well and achieved high accuracies. Additionally, we have
trained a decision tree to distinguish toric (4,6) curves as well. Finally, we
present an application of these analytic rules to construct local base
configurations with interesting gauge groups such as SU(3).
