2. Reinforcement Learning
​

3. Q-Learning
● ​Define Q-function using Bellman Equation
● Take action that gives you the maximum reward or Q-value

4. Deep Q-Network

5. Keras
Architecture

6. Improvements & Optimizations
● Experience Replay
○ Q-Learning may not be stable sometimes
○ Can also use human gameplay
● Exploration Vs. Exploitation ​
○ ε-Greedy Exploration
○ Decrease ε exponentially
● Initialization Strategy

7. Training the Deep Q-Network
