## Conceptual

### ISLR Section 5.4

• 2 (a-f), and calculate $$e^{-1}$$ to a few decimal places for comparison
• 3

• 2
• 5

## Optional

The remaining exercises are option and will not be graded.

### Mathematics practice

• Can resampling methods be useful for addressing OOD generalization? If not, then why? If so, then how?

• Write out the objective function of the lasso for the case of linear regression with one predictor variable. Use calculus to find an expression for the solution (hint: you may need to consider cases)

### Applied practice

• ISLR Section 5.4, problem 8

• ISLR Section 6.6, problem 9 (a-d)

• ISLR Section 7.9, problem 9 (a-c)
