Which AI/ML concept best describes the learning approach for this use case?

Generative AI, because the system creates a new sentiment label for each review.

Reinforcement learning, because the model improves by receiving rewards after each customer review is processed.

Unsupervised learning, because the system analyzes text without requiring human interaction at prediction time.

Supervised learning, because the model learns from examples that include both inputs and known labels.
