The A3C algorithm was published in June 2016 by the combined team of Google DeepMind and MILA. It is simpler and has a lighter framework that used the asynchronous gradient descent to optimize the deep neural network. It was faster and was able to show good results on the multi-core CPU instead of GPU. One of A3C's big advantages is that it can work on continuous as well as discrete action spaces. As a result, it has opened the gateway for many new challenging problems that have complex state and action spaces.
We will discuss it at a high note here, but we will dig deeper in Chapter 6, Asynchronous Methods. Let's start with the name, that is, asynchronous advantage actor-critic (A3C) algorithm and unpack ...
