8 categories × 20 noisy samples with random sensory dropout. Flat ART clustering — with the right vigilance, both a general "fish" hub and species-level hubs emerge without any forced hierarchy.
Items: pine, oak, rose, daisy, robin, canary, sunfish, salmon Pools: Color, Locomotion, Covering, BodyParts, Habitat Note: Some samples have missing values (dropout) filled with 0 — expect noisy similarity per pool.
