  "Description": "Fits a Classifier Chain Network (CCN) for multi-label\nbinary classification. The model jointly learns label\ndependencies through a chain structure and optimizes an Lq norm\naggregated cross-entropy loss. Provides methods for prediction,\nmodel summary, and k-fold cross-validation with grid search\nover hyperparameters. The methodology is described in Touw and\nVan de Velden (2025) <doi:10.1016/j.eswa.2025.128048>.",
