Since Part 1 of this series, we have framed Reinforcement Learning as a Markov Decision Process environment with discrete states and actions with their corresponding state-action values Q(s,a) stored in a tabular manner. This means that you can imagine a 2-dimensional table, with a row index presented by states and a column index represented by actions. The table entries are then the array of Q(s,a) values. This simplified paradigm has allowed us to gain intuition about how a decision-making agent learns as it traverses through a bite-sized environment.

In real-world applications, however, there can either be an… Read the full blog for free on Medium.
