Results

An intro spiel here...

(For mathematical definitions of the various metrics, please see 2018:Patterns_for_Prediction#Evaluation_Procedure.)

SymMono

Here are some results (cf. Figures 1-3), and some interpretation. Don't forget these as well (Figures 4-6), showing something.

Remarks on runtime appropriate here too.

SymPoly

And so on.

Figures

SymMono

2017 Mono R est.png

Figure 1. Establishment recall averaged over each piece/movement. Establishment recall answers the following question. On average, how similar is the most similar algorithm-output pattern to a ground-truth pattern prototype?

2017 Mono P est.png

Figure 2. Establishment precision averaged over each piece/movement. Establishment precision answers the following question. On average, how similar is the most similar ground-truth pattern prototype to an algorithm-output pattern?

2017 Mono F1 est.png

Figure 3. Establishment F1 averaged over each piece/movement. Establishment F1 is an average of establishment precision and establishment recall.

2017 Mono R occ 75.png

Figure 4. Occurrence recall () averaged over each piece/movement. Occurrence recall answers the following question. On average, how similar is the most similar set of algorithm-output pattern occurrences to a discovered ground-truth occurrence set?

2017 Mono P occ 75.png

Figure 5. Occurrence precision () averaged over each piece/movement. Occurrence precision answers the following question. On average, how similar is the most similar discovered ground-truth occurrence set to a set of algorithm-output pattern occurrences?

2017 Mono F1 occ75.png

Figure 6. Occurrence F1 () averaged over each piece/movement. Occurrence F1 is an average of occurrence precision and occurrence recall.

2017 Mono R3.png

Figure 7. Three-layer recall averaged over each piece/movement. Rather than using as a similarity measure (which is the default for establishment recall), three-layer recall uses , which is a kind of F1 measure.

2017 Mono P3.png

Figure 8. Three-layer precision averaged over each piece/movement. Rather than using as a similarity measure (which is the default for establishment precision), three-layer precision uses , which is a kind of F1 measure.

2017 Mono TLF1.png

Figure 9. Three-layer F1 (TLF) averaged over each piece/movement. TLF is an average of three-layer precision and three-layer recall.

Mono Coverage.png

Figure 10. Coverage of the discovered patterns of each piece/movement. Coverage measures the fraction of notes of a piece covered by discovered patterns.

2017 Mono LC.png

Figure 11. Lossless compression achieved by representing each piece/movement in terms of patterns discovered by a given algorithm. Next to patterns and their repetitions, also the uncovered notes are represented, such that the complete piece could be reconstructed from the compressed representation.

SymPoly

2017 Poly R est.png

Figure 12. Establishment recall averaged over each piece/movement. Establishment recall answers the following question. On average, how similar is the most similar algorithm-output pattern to a ground-truth pattern prototype?

Figure 13. Establishment precision averaged over each piece/movement. Establishment precision answers the following question. On average, how similar is the most similar ground-truth pattern prototype to an algorithm-output pattern?

2017 Poly F1 est.png

Figure 14. Establishment F1 averaged over each piece/movement. Establishment F1 is an average of establishment precision and establishment recall.

2017 Poly R occ 75.png

Figure 15. Occurrence recall () averaged over each piece/movement. Occurrence recall answers the following question. On average, how similar is the most similar set of algorithm-output pattern occurrences to a discovered ground-truth occurrence set?

2017 Poly F1 occ 75.png

Figure 17. Occurrence F1 () averaged over each piece/movement. Occurrence F1 is an average of occurrence precision and occurrence recall.

Figure 18. Three-layer recall averaged over each piece/movement. Rather than using as a similarity measure (which is the default for establishment recall), three-layer recall uses , which is a kind of F1 measure.
