Class Evaluation

Known Subclasses:

music_halfspan.Formalism.Evaluation

Functions for evaluating tonal space paths and parse results.

Class Variables

tonal_space_alignment_costs = None
Performs an alignment of two tonal space paths and returns a dictionary of costs incurred in the optimal alignment.

tonal_space_distance = None
Performs an alignment of two tonal space paths and computes a distance metric between them.

tonal_space_alignment_costs

Performs an alignment of two tonal space paths and returns a dictionary of costs incurred in the optimal alignment. The values must include 'deletions', 'substitutions' and 'insertions' and may also include more fine-grained information, like 'root_subs' and 'function_subs'.

Value:

None

tonal_space_distance

Performs an alignment of two tonal space paths and computes a distance metric between them. The metric is assumed to be based on edit distance, so to have a minimum value of 0 (identity) and maximum the length of the longer sequence.

Value:

None
