updating estimates of value (v^(st​)) using estimates of other states’ values (v^(st+1​)). 2. What does the hat over the v in v^(st​) denote for a value function? ➥That it is an estimate, not the true value. 3. How should we interpret the two terms of the TD Update Equation,v^(st​) ← (1−α) v^ (st​)
