The tidal marsh and tidal flats in the intertidal zones of Chiloé, Chile are highly productive ecosystems that provide essential ecosystem services and preserve local biodiversity. However, they face increasing pressure from human activities. This study evaluated the cumulative r...

A new perspective on centroid algorithms for unsupervised discrete clustering in Riemannian manifolds: an approach via optimization

Abstract Clustering is an unsupervised learning technique used to discover hidden structures in data. By identifying patterns and similarities among objects, this methodology enables the organization of datasets into homogeneous groups. This work presents a new perspective on a s...
