You have a dataset with features such as location, size, number of bedrooms, and the corresponding house prices. You need to build a model to predict the price of a new house. Which approach fits best?
A
Unsupervised Learning
B
Reinforcement Learning
C
Supervised Learning (Regression)
D
Clustering
Explanation:
This is a supervised learning regression problem because:
Labeled Data: You have a dataset with features (location, size, number of bedrooms) and corresponding house prices (labels/target variable).
Prediction Task: The goal is to predict a continuous numerical value (house price) based on input features.
Regression vs Classification: Since the target variable (price) is continuous, this is a regression problem, not classification.
Why other options are incorrect:
A) Unsupervised Learning: Used for finding patterns in unlabeled data (e.g., clustering, dimensionality reduction). Here we have labeled data.
B) Reinforcement Learning: Used for decision-making problems where an agent learns through rewards/penalties in an environment (e.g., game playing, robotics).
D) Clustering: A specific type of unsupervised learning for grouping similar data points, not for predicting continuous values.
Key Machine Learning Concepts:
Supervised Learning: Training on labeled data to make predictions
Regression: Predicting continuous numerical values
Classification: Predicting discrete categories/classes
In AWS context, this could be implemented using services like Amazon SageMaker for building, training, and deploying machine learning models.
