A "Guess the Clustering Algorithm" quiz is circulating on X: four scatter plots (A/B/C/D) show different clusterings of the same two-spirals-plus-blob dataset, one including noise points labeled -1, challenging readers to identify which algorithm produced each. It tests intuition for how methods like K-Means, DBSCAN, spectral clustering, and GMM behave on different data shapes.
