Reinforcement Learning is one of the most intricate fields of Machine Learning, due to its mathematical complexity, as well as the ambitious tasks it tries to achieve.Simply put, the final goal of a RL algorithm is to make an agent capable of acting in an environment as to max...
SARSA agents use the following training algorithm. To configure the training algorithm, specify options using anrlSARSAAgentOptionsobject. Initialize the criticQ(S,A;ϕ) with random parameter values inϕ. For each training episode: Get the initial observationSfrom the environment. ...
In this paper, we investigate the application of reinforcement learning in the learning of chasing behaviours of non-player characters (NPCs). One popular method for encoding intelligent behaviours in game is by scripting where the behaviours on the scen
