MRGAN: Multi-Criteria Relational GAN for Lyrics-Conditional Melody Generation
Bibliographic record
Abstract
Music generation, as a creativity problem, attracts growing attention from artificial intelligence researchers. Among the challenging tasks, lyrics-conditional melody generation aims to leverage natural language processing (NLP) techniques to generate music from texts, for which Generative Adversarial Networks (GAN) has become a promising unsupervised solution. The adversarial training of two agents, i.e., generator and discriminator, allows GAN to achieve a better generation performance and has been proven effective in conditional generation tasks. In this paper, we propose the multi-criteria relational GAN (MRGAN), which includes a relation memory-based generator and two discriminators with a unique discrimination criterion each. The relational memory in the generator is adopted for long-time dependency modeling. Meanwhile, the two discriminators can judge both musical quality and conditional correspondence. Based on the bilingual evaluation understudy (BLEU) score, a new metric, named Music-BLEU, has also be designed to evaluate the lyrics-conditional melody generation. Experimental results verify that MRGAN outperforms existing approaches in related key metrics.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
