Abstract

fetched live from OpenAlex

Music notation represents what a composer creates. This research is concerned with the problem of compression, without distortion, of complete scores of musical pieces. The musical score source has many interesting characteristics which set it apart from other information sources; for example, it is a collection of parallel 'parts'; the durations of symbols (notes) are variable; and the transitions between notes in different parts need not be simultaneous. These distinguishing features are discussed and incorporated into the procedure described in this work. The research consists of three parts. The first is the design of a representation system allowing musical scores to be stored on digital media. The second is the development of a simple music editor and the compilation of two pieces of music. The third is the design and implementation of a compression algorithm. Significantly higher compression ratios are achieved using the designed algorithm vis-a-vis those achieved using a standard general data compression algorithm.

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.
