Within group theory, geometric group theory studies groups by equipping them with a metric and thus regarding them as metric spaces.
For finitely generated groups this is typically done by regarding the group’s elements as the vertices of a graph – the Cayley graph – whose edges connect elements related by multiplication with a generator. The corresponding graph distance then equips the group with a metric.
The methods of geometric group theory overlap with kernel methods in machine learning.
