Abstract

fetched live from OpenAlex

Music genre classification is a challenging problem due to the subjective and complex nature of music perception. This project explores three complementary approaches to genre classification: audio-based classification using Mel-spectrograms and Convolutional Neural Networks (CNN), lyrics-based classification using RoBERTa for natural language processing, and a multimodal classification approach that integrates both modalities. The audio-based approach achieved remarkable performance improvements through augmentation techniques, while the lyrics-based model demonstrated effective text comprehension using pre-trained transformers. Finally, a multimodal approach that combines Mel-spectrograms and lyrics through concatenation achieved the highest accuracy, underscoring the advantages of integrating diverse data modalities. These results demonstrate the potential of multimodal deep learning for complex classification tasks, opening the way to improved music retrieval systems.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
