An introduction to frequent subgraph mining

Posted on 2017-01-30 by Philippe Fournier-Viger

In this blog post, I will give an introduction to an interesting data mining task called frequent subgraph mining, which consists of discovering interesting patterns in graphs. This task is important since data is naturally represented as graph in many domains (e.g. … Continue reading →
