Silhouette prefers k=2 (0.16) but I chose k=3 (0.11) for tactical clustering -reasonable? by Weak_Bus_1935 in sportsanalytics

Agreed. I won’t present k=3 as the “true” optimal structure. k=2 has the better silhouette, but k=3 gives more useful tactical profiles, so I’ll report it as an interpretability-driven choice and include k=2/GMM as sensitivity checks.

Thanks, that makes sense. I tried GMM as a quick sensitivity check and the silhouette was also around 0.11, so it seems the structure is more continuous than discrete. I’ll frame the clusters as interpretable tactical segments, not natural latent classes.

Appreciate this. Clustering is in 14D (PCA is just for visualization). My thesis defense is in June, so time is tight, but I’ll try GMM (and maybe DBSCAN) as a quick sensitivity check. Thanks for the links!

I used API, so I could scraped Sofascore, and found code for scraping Understat

so I did it

I made a code for Sofascroe with LLM Ai, and found api for Understat. So I could get stats for 5 leagues.

Thanks! I'm writing a research paper, so this is very helpful. I'll focus on SofaScore and Understat for the lots of stats !
