FRODO: Free rejection of Out-of-distribution samples
use FRODO simply by
import model
from tf_frodo import FRODO
model_with_frodo = FRODO(model).fit(x_validation)
results = model_with_frodo.predict(x_test)
assert results["model_outputs"] == model(x_test)
results["FRODO"] # Rejection scores for each sample in x_test
