Centrality of Topics and Areas

The (degree and betweenness) centrality of the vertices - areas and topics - is depicted in a table.

Below, the image of the resulting network shows how the relationships between areas and topics are distributed. Numbers refer to the 79 topics (see their descriptions here).

It is possible to see the, not surprising, prominence of reinforcement learning. However, other conclusions can be drawn:

• Most of the 10 areas paired with (MA)RL

• Coordination and control remain popular topics

• Most areas retain their main respective focusses (i.e., are paired with their original topics)

• GT: seems to have a weak relation to MARL
