Heuristic Algorithm for Univariate Stratification Problem
José Brito, Gustavo Semaan, Leonardo de Lima +1
In sampling theory, stratification corresponds to a technique used in surveys, which allows segmenting a population into homogeneous subpopulations (strata) to produce statistics w…
HELIX: Data-driven characterization of Brazilian land snails
Marcelo N. Almeida, Rodolfo Alves de Oliveira, Luiz Olmes +4
Decision-support systems benefit from hidden patterns extracted from digital information. In the specific domain of gastropod characterization, morphometrical measurements support…
