What is the main difference between supervised and unsupervised learning?

Supervised learning trains models based on a combination of labeled and unlabeled data, while unsupervised learning uses only labeled data.

Supervised learning uses labeled data, while unsupervised learning uses unlabeled data. (correct)

Supervised learning classifies new samples by similarity, while unsupervised learning groups objects based on similarities.

Supervised learning builds models based on similarities, while unsupervised learning uses reinforcement signals.

Which type of learning involves learning behavior from the environment to maximize rewards?

Reinforcement learning (correct)

Supervised learning

Unsupervised learning
