The accuracy of random forest is over 0.99

[Kevin mei]

I fit the easy random forest model，just like this
from sklearn.ensemble import RandomForestClassifier
RandomForestClassifier(n_estimators=10, random_state=2019)

TABLE IV. High-level features in yours paper

How much of the training data did you use?

I tried just using 1 file (~20k events, so granted it might not be enough), and only got up to ~80% test accuracy. On the other hand, if I use the training data, then it's >99% accuracy.

How is the validation accuracy defined here?
