Question 1
What happens if the step-size (ΞΌ) is set too high in the LMS algorithm?
- It converges too quickly
- The algorithm may diverge
- It remains stable
π‘ Hint: Consider the balance between speed and stability.
Question 2
True or False: Choosing a very small ΞΌ guarantees fast convergence in the LMS algorithm.
- True
- False
π‘ Hint: Think about the extremes of adjustment size.
