Judo Attack Combinations as Networks in R
Visualizing Combos in Judo in R
A data scientist and martial artist applies network analysis to Judo, modeling throwing techniques as nodes and their combinations as directed edges. Using R and the igraph package, he visualizes an interactive network of attack sequences and analyzes degree centrality to identify key initiators and finishers. Fitting degree distributions reveals a truncated power law, indicating a few highly connected techniques with natural limits. The post offers insights for both Judo enthusiasts and network scientists, with links to ecological applications.
The truncated power law provided the best fit for the degree distribution, suggesting that while a few techniques are highly connected within attack sequences, there’s a natural limit to how dominant any single technique can be.
