Webprising nding of this paper is that when Q-learning is applied to games, a pure greedy value-based approach causes Q-learning to endlessly \ ail" in some games instead of converging. For the rst time, we provide a detailed picture of the behavior of Q-learning with -greedy exploration across the full spectrum of 2-player 2-action games. WebIn DeepMind's paper on Deep Q-Learning for Atari video games ( here ), they use an epsilon-greedy method for exploration during training. This means that when an action is selected in training, it is either chosen as the action with the highest q-value, or a random action.
WebSep 17, 2024 · Q learning is a value-based off-policy temporal difference (TD) reinforcement learning. Off-policy means an agent follows a behaviour policy for choosing the action to reach the next state... WebNext we need a way to update the Q-Values (value per possible action per unique state), which brought us to: If you're like me, mathematic formulas like that make your head spin. Here's the formula in code: new_q = (1 - LEARNING_RATE) * current_q + LEARNING_RATE * (reward + DISCOUNT * max_future_q) That's a little more legible to me!

However, is behavior policy can be anything that continues to visit all state action pairs during learning. One possible policy is epsilon greedy. The difference here between the target and behavior policies confirms that Q-learning is off-policy. brashland chestWebThe epsilon-greedy approach is very popular.
