Reinforcement learning has achieved remarkable results in areas such as simulated robotics or at playing Atari computer games. As reinforcement learning agents learn through exploration by trial-and-error, training in the real world would result in undesirable actions leading to possible damage to the system and its environment. To train a reinforcement learning agent using functional approximations such as the neural network, the agent interacts with the world, the world returns a reward if the action used was good or penalty, if not. This reward is used to train the network. During training, the reward function must increase and the loss function should converge to zero. A poor choice of hyperparameters such as the architecture of the network can lead to bad results. Therefore we may have to tune the hyperparameters several times to get a better result. Every time we tune the parameters, we have to restart the training. A big challenge in training an agent in the real world is learning from limited samples. Almost all of these real systems are either slow, fragile or so expensive that the data they generate is expensive, and policy learning must be data efficient. Off-policy reinforcement learning aims to leverage experience collected from prior policies for sample-efficient learning.

Task

The goal of this work is to train a driving policy efficiently by using an off-policy reinforcement learning algorithm. To drive a car safely to its destination.
