addLabelDefinitions
Add label definitions to labeled signal set
Description
Examples
Add Label Definition
Load a labeled signal set containing recordings of whale songs.
load whales
lss
lss = labeledSignalSet with properties: Source: {2x1 cell} NumMembers: 2 TimeInformation: "sampleRate" SampleRate: 4000 Labels: [2x3 table] Description: "Characterize wave song regions" Use labelDefinitionsHierarchy to see a list of labels and sublabels. Use setLabelValue to add data to the set.
Create a label definition that specifies whether a signal corresponds to a calf or to an adult whale.
calf = signalLabelDefinition("Calf", ... LabeldataType="logical",DefaultValue=false, ... Description="Is the specimen a calf, or an adult?")
calf = signalLabelDefinition with properties: Name: "Calf" LabelType: "attribute" LabelDataType: "logical" ValidationFunction: [] DefaultValue: 0 Sublabels: [0x0 signalLabelDefinition] Tag: "" Description: "Is the specimen a calf, or an adult?" Use labeledSignalSet to create a labeled signal set.
Add the definition to the labeled signal set. Retrieve the names of the labels.
addLabelDefinitions(lss,calf) getLabelNames(lss)
ans = 4x1 string
"WhaleType"
"MoanRegions"
"TrillRegions"
"Calf"
Create a label definition that specifies the sex of the whale. Add the label to the set as a sublabel of 'WhaleType'
.
sx = signalLabelDefinition("Sex",LabelDataType="categorical", ... Categories=["male" "female"]); addLabelDefinitions(lss,sx,"WhaleType") labelDefinitionsHierarchy(lss)
ans = 'WhaleType Sublabels: Sex MoanRegions Sublabels: [] TrillRegions Sublabels: TrillPeaks Calf Sublabels: [] '
Input Arguments
lss
— Labeled signal set
labeledSignalSet
object
Labeled signal set, specified as a labeledSignalSet
object.
Example:
specifies a two-member set of random
signals containing the attribute labeledSignalSet
({randn(100,1)
randn(10,1)},signalLabelDefinition('female'))'female'
.
lbldefs
— Signal label definitions
signalLabelDefinition
object | vector of signalLabelDefinition
objects
Signal label definitions, specified as a signalLabelDefinition
object or
a vector of signalLabelDefinition
objects.
Example:
can label a region of a signal in which a patient is asleep.signalLabelDefinition
("Asleep",'LabelType','roi','LabelDataType','logical')
lblname
— Label name
character vector | string scalar
Label name, specified as a character vector or a string scalar.
Example: signalLabelDefinition("Asleep",'LabelType','roi')
specifies a label of name "Asleep"
for a region of a signal in which
a patient is asleep during a clinical trial.
