Class BackoffBuilder

object --+
         |
        BackoffBuilder

Known Subclasses:

Defines the interface and common functions for models that assign a semantics directly to an input sequence.

The evaluation interface is similar to the Tagger interface.

Instance Methods

[hide private]

__init__(self, input, options={}, logger=None)
x.__init__(...) initializes x; see help(type(x)) for signature source code

_get_name(self)

source code

_get_input_length(self)
Should return the number of words (chords) in the input, or some other measure of input length appropriate to the type of input.

source code

jazzparser.formalisms.base.semantics.lambdacalc.Semantics subclass instance

get_tonal_space_path(self, rank=0)
This is the main interface method.

source code

get_all_paths(self)
Gets a list of all the tonal space paths, highest rank first.

init(self, input, options=`{}`, logger=None)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__: (inherited documentation)

get_tonal_space_path(self, rank=0)

source code

This is the main interface method.

Parameters:

rank (int) - the rank of the path the get, where 0 is the highest ranked path

Returns: jazzparser.formalisms.base.semantics.lambdacalc.Semantics subclass instance

the rankth highest ranked path through the tonal space for this sequence. Returns None if there is no path with this rank.

get_all_paths(self)

source code

Gets a list of all the tonal space paths, highest rank first. Just a convenience method to get all the paths using get_tonal_space_path for every rank (self.num_paths).

Get Method:: _get_input_length(self) - Should return the number of words (chords) in the input, or some other measure of input length appropriate to the type of input.
