# FullyConnectedNetworkMultiLabelClassifier A classifier that uses a multi-label fully-connected network. ``` struct FullyConnectedNetworkMultiLabelClassifier where Scalar : MLShapedArrayScalar, Scalar : BinaryFloatingPoint, Scalar : Decodable, Scalar : Encodable, Label : Comparable, Label : Decodable, Label : Encodable, Label : Hashable ``` ## Topics ### Creating a classifier [`init(labels: Set, configuration: FullyConnectedNetworkConfiguration)`](/documentation/CreateMLComponents/FullyConnectedNetworkMultiLabelClassifier/init(labels:configuration:)) Creates a full-connected network multi-label classifier. ### Getting the properties [`var configuration: FullyConnectedNetworkConfiguration`](/documentation/CreateMLComponents/FullyConnectedNetworkMultiLabelClassifier/configuration) The fully-connected network configuration. [`static var defaultConfiguration: FullyConnectedNetworkConfiguration`](/documentation/CreateMLComponents/FullyConnectedNetworkMultiLabelClassifier/defaultConfiguration) The default fully-connected network configration. [`var labels: Set`](/documentation/CreateMLComponents/FullyConnectedNetworkMultiLabelClassifier/labels) The set of possible labels. ### Fitting a classifier [`func fitted(to: Input, eventHandler: EventHandler?) async throws -> FullyConnectedNetworkMultiLabelClassifierModel`](/documentation/CreateMLComponents/FullyConnectedNetworkMultiLabelClassifier/fitted(to:eventHandler:)) Fits a fully-connected network multi-label classifier model to a sequence of examples. [`func fitted(to: Input, validateOn: Validation, eventHandler: EventHandler?) async throws -> FullyConnectedNetworkMultiLabelClassifierModel`](/documentation/CreateMLComponents/FullyConnectedNetworkMultiLabelClassifier/fitted(to:validateOn:eventHandler:)) Fits a fully-connected network multi-label classifier model to a sequence of examples. [`typealias Annotation`](/documentation/CreateMLComponents/FullyConnectedNetworkMultiLabelClassifier/Annotation) The annotation type. [`typealias Transformer`](/documentation/CreateMLComponents/FullyConnectedNetworkMultiLabelClassifier/Transformer) The transformer type created by this estimator. ### Default Implementations [SupervisedEstimator Implementations](/documentation/CreateMLComponents/FullyConnectedNetworkMultiLabelClassifier/SupervisedEstimator-Implementations) [UpdatableSupervisedEstimator Implementations](/documentation/CreateMLComponents/FullyConnectedNetworkMultiLabelClassifier/UpdatableSupervisedEstimator-Implementations) ## Relationships ### Conforms To [`UpdatableSupervisedEstimator`](/documentation/CreateMLComponents/UpdatableSupervisedEstimator) [`Copyable`](/documentation/Swift/Copyable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`SupervisedEstimator`](/documentation/CreateMLComponents/SupervisedEstimator) [`Sendable`](/documentation/Swift/Sendable) [`Escapable`](/documentation/Swift/Escapable) --- Copyright © 2026 Apple Inc.
