Question 1: True or false

mediumAI-checkedPolicy Gradient & Actor-Critic

REINFORCE with baseline updates θ←θ+α (Gt−b(St)) ∇θln⁡π(At∣St,θ)\theta \leftarrow \theta + \alpha\,\big(G_t - b(S_t)\big)\,\nabla_\theta \ln \pi(A_t \mid S_t, \theta). True or false: subtracting b(St)b(S_t) biases the expected update unless b(St)b(S_t) equals the true state value vπ(St)v_\pi(S_t).
