كيف تستخدم آلية الرفض داخل تطبيقات بايثون؟

from openmcr import OpenMCR
from sklearn.ensemble import RandomForestClassifier

# Initialize Open-MCR with a RandomForestClassifier
model = RandomForestClassifier()
mcr_model = OpenMCR(model, rejection_threshold=0.3)

# Train the model
mcr_model.fit(X_train, y_train)

# Make predictions with rejection
predictions = mcr_model.predict(X_test)
