Q&A

What is linear regression?

Linear regression is a learning algorithm that fits linear models to predict values based on input features.

How can linear regression predict house prices?

Linear regression analyzes factors such as size and number of bedrooms to predict house prices based on historical data.

What is the hypothesis in linear regression?

The hypothesis is a linear function that maps input features to predicted output values.

What is the cost function in linear regression?

The cost function measures the squared difference between predicted and actual output values, allowing for optimization of parameter values.

How does gradient descent work in linear regression?

Gradient descent is an iterative algorithm that adjusts parameter values to minimize the cost function and find optimal model performance.
