"""Dueling DQN class
Paper: https://arxiv.org/abs/1511.06581
Attributes:
network (str): The network type of the Q-value function.
Supported types: ["cnn", "mlp"]
env (Environment): The environment that the agent is supposed to act on
batch_size (int): Mini batch size for loading experiences
gamma (float): The discount factor for rewards
layers (:obj:`tuple` of :obj:`int`): Layers in the Neural Network
of the Q-value function
lr_value (float): Learning rate for the Q-value function
replay_size (int): Capacity of the Replay Buffer
buffer_type (str): Choose the type of Buffer: ["push", "prioritized"]
max_epsilon (str): Maximum epsilon for exploration
min_epsilon (str): Minimum epsilon for exploration
epsilon_decay (str): Rate of decay of epsilon (in order to decrease
exploration with time)
seed (int): Seed for randomness
render (bool): Should the env be rendered during training?
device (str): Hardware being used for training. Options:
["cuda" -> GPU, "cpu" -> CPU]
