Paper

playing atari with deep reinforcement learning (NIPS 2013)
Human-Level Control through Deep Reinforcement Learning (NIPS 2015)

TO DO

Test: Atari
- more complex ConvNet model
use TensorBoard
- average loss
- average q
- average reward (consecutive 100 episode)
- episode reward

Model

1. MLPv1

hidden layer (16, 64, 32)
AdamOptimizer

2. ConvNetv1

2 Fully Connected Layers (hidden_size [128, 32])
AdamOptimizer

3. ConvNetv2

5 Conv + MaxPool Layers (kernel_size [7, 5, 3, 3, 3], filters [126, 256, 512, 512, 512]
