* Currently this is specific to the case of discretizing a continuous action space. Can easily be adapted to other case by feeding the kNN otherwise, and removing the usage of a discretizing output action filter

<p>Coach supports many state-of-the-art reinforcement learning algorithms, which are separated into three main classes -
|
||
value optimization, policy optimization and imitation learning.
|
||
A detailed description of those algorithms can be found by navigating to each of the algorithm pages.</p>
