Clustering Algorithms for Sepak Bola Team Performance Analisiss

Clustering algorithms group football teams based on similarity across multiple performance dimensions, revealing natural team archetypes that inform prediction models.

K-Means Clustering for Team Archetypes

K-means clustering partitions teams into k groups based on their multi-dimensional performance profiles. When applied to features like possession percentage, pressing intensity, passing directness, and defensive line height, k-means typically identifies 4-6 natural team archetypes: dominant possession teams, direct counter-attacking teams, high-pressing aggressive teams, low-block defensive teams, balanced mid-table teams, and chaotic high-scoring/high-conceding teams.

Tactical Matchup Analysis

Clustering enables sophisticated tactical matchup analysis. Historical data shows that certain team archetypes perform significantly better or worse against specific opposition styles. Low-block defensive teams historically perform well against high-possession teams (who struggle to break down organized defenses) but poorly against direct teams (who bypass the press with long balls).

Hierarchical Clustering for League Profiling

Hierarchical clustering — which builds a tree of nested clusters — is valuable for understanding how leagues and teams relate to each other. Applied across multiple European leagues, hierarchical clustering reveals which leagues share similar playing styles (the Premier League and Bundesliga cluster together due to high intensity, while La Liga and Serie A cluster together due to tactical emphasis). These league-level clusters help calibrate cross-league predictions for European competition.

Dynamic Clustering Throughout the Season

Team playing styles are not static: a managerial change, key injury, or tactical evolution can shift a team's cluster membership mid-season.
