The regression model is a fundamental type of supervised machine learning algorithm that is specifically designed to make numeric predictions. In regression tasks, the goal is to predict a continuous numerical value based on input features. This contrasts with classification, which predicts discrete labels.

According to AWS documentation:

“Regression models are used for predicting a continuous value. Examples include predicting house prices, stock market prices, or customer credit limits.”

Option A (Diffusion) relates to generative models and is not primarily used for numeric prediction.

Option C (Transformer) is a neural network architecture, often used for sequence modeling tasks (e.g., NLP).

Option D (Multi-modal) describes a model handling multiple data types, not specifically numeric prediction.
