Question 1
You notice that as you increase the data size, both training and validation scores of your model plateau at low values. What should you assess about this model, and what corrective measures could you take?
π‘ Hint: Reflect on the reasons why models may not fit data well.
Question 2
While examining Validation Curves for your Random Forest model, you see that validation accuracy peaks at max_depth=10 and then falls sharply. How would you interpret this, and what recommendations would you make?
π‘ Hint: Consider what happens when you add complexity beyond optimal limits.
