Article Title: Who is calling? Optimizing source identification from marmoset vocalizations with hierarchical machine learning classifiers
doi: 10.1098/rsif.2023.0399
Figure Lengend Snippet: Comparing non-hierarchical and hierarchical approaches for classifying calls based on source identity. Mean ± s.d. precisions and recalls with corresponding p -values for testing the hypotheses: mean precisions/recalls of non-hierarchical = hierarchical. Both approaches were tested using the Balanced-X datasets.
Article Snippet: We first trained AdaBoost (using MATLAB's ‘fitcensemble’, ‘AdaboostM1′, and ‘AdaboostM2′ functions) on Imbalanced-X, Balanced-X, Balanced197-X, and Balanced99-X datasets to classify calls based on source identity—as a direct or ‘non-hierarchical approach’ (in contrast to the hierarchical approach that was used later)—to determine source identity from calls.
