Exploring Authorial Signatures in Brazilian Modernist Poetry through Stylometric Representations Using Machine Learning

This record contains the versioned reproducibility package for a study of authorship attribution in a balanced corpus of 250 poems by five Brazilian modernist poets. It includes source code, corpus and bibliographic metadata, predefined splits, repeated-cross-validation assignments, fold-specific feature matrices, matrices for reported ablations, and derived experimental outputs. Full poem texts are not redistributed because the source editions may remain protected by copyright. Page-level and constituent-work locators were not retained for all documents.
