Suppose you are working on weather prediction, and use a learning algorithm to predict tomorrow's temperature (in degrees Centigrade/Fahrenheit). Would you treat this as a classification or a regression problem?

• Regression

• Classification

• None of the Above

What is the main goal of machine learning?

• To make computers intelligent

• To automate manual tasks

• To enable computers to learn from data

• To create self-aware machines

What is the purpose of regularization in linear regression?

• To make the model more complex

• To avoid underfitting

• To encourage overfitting

• To reduce the complexity of the model

What is the primary goal of feature engineering in supervised machine learning?

• To reduce model complexity 

• To improve model interpretability 

• To enhance model performance

• To increase the number of training samples
