I want to contribute to the open source deep learning community, so that it reaches to more and more engineers. Figure 1: Screen shots from five Atari 2600 Games: (Left-to-right) Pong, Breakout, Space Invaders, Seaquest, Beam Rider an experience replay mechanism [13] which randomly samples previous transitions, and thereby smooths the training distribution over many past behaviors. The authors define an example quantitative measure of gamer engagement and incorporate that into the DQN learning reward function. However, sometimes you don't care about fair comparisons. You can vote up the examples you like or vote down the ones you don't like. Experiments by: Ashish Budhiraja. dqn、trpo、a3cの3つの強化学習アルゴリズムで実験していて、攻撃方法はfgsmです。 下図はPongというAtariのゲームの例です。 ボールは図中の矢印の方向に動こうとしているので、paddleを下に動かせばボールをとらえることができるという状況です。. /ale -game_controller rlglue -use_starting_actions true-random_seed time -display_screen true-frame_skip 4 /tmp/pong.

DQN 超 分析 [Sprague 2015] 図 [Sprague 2015] 引用 DQN( [Mnih et al. The "well-tuned proposed model and not-very-well-tuned baseline" is something I feel nearly every researcher is guilty of, including myself :) It's especially pronounced however when people compare to a baseline from paper X (usually by copying and pasting the number) which may be a year or more old. Initialize DQN parameter with random values Initialize replay memory Mwith capacity N for each episode do Initialize state s.
