                 WeightedChordLabelInput

Input wrapper for a lattice of chord labels, including a set of chord labels for each timestep, each with a probability. The labels themselves are similar to the chord in a DbInput and are represented using jazzparser.misc.chordlabel.data.ChordLabels.

The lattice should be a list of timesteps. Each timestep should be a list of (label,prob) tuples, where label is a ChordLabel and prob is a probability.

source code

slice(self, start=None, end=None)
Subclasses should provide a way of slicing (taking a subsequence of) the input that returns an input of the original type.

source code

apply_ratio_beam(self, ratio=0.0001)
Applies a beam to remove all values from the lattice whose probability is less than the given ratio of the highest probability for that timestep.
