<h2>Scikit-Learn Code Example</h2>
<pre><code>from sklearn.ensemble import RandomForestClassifier
from sklearn.model_selection import train_test_split
Initialize the model
n_estimators = number of trees
clf = RandomForestClassifier(n_estimators=100, max_depth=2, random_state=0)
Fit to training data
clf.fit(X_train, y_train)
Predict class labels
y_pred = clf.predict(X_test)
Exam Tip: Always check your feature_importances_ attribute to understand which variables are driving your model's decisions. This is crucial for model explainability.
