# NormalizationScaler An estimator that normalizes the input values using a normalization strategy. ``` struct NormalizationScaler where Element : BinaryFloatingPoint, Element : Decodable, Element : Encodable ``` ## Topics ### Creating a scaler [`init(norm: NormalizationScaler.NormalizationStrategy)`](/documentation/CreateMLComponents/NormalizationScaler/init(norm:)) Creates a normalization scaler. [`enum NormalizationStrategy`](/documentation/CreateMLComponents/NormalizationScaler/NormalizationStrategy) A normalization strategy. ### Getting the normalization [`var norm: NormalizationScaler.NormalizationStrategy`](/documentation/CreateMLComponents/NormalizationScaler/norm) The normalization strategy. ### Fitting [`func fitted(to: S, eventHandler: EventHandler?) throws -> NormalizationScaler.Transformer`](/documentation/CreateMLComponents/NormalizationScaler/fitted(to:eventHandler:)) Fits a normalization scaler to a sequence of elements. ### Default Implementations [Estimator Implementations](/documentation/CreateMLComponents/NormalizationScaler/Estimator-Implementations) ## Relationships ### Conforms To [`Estimator`](/documentation/CreateMLComponents/Estimator) [`Sendable`](/documentation/Swift/Sendable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) --- Copyright © 2026 Apple Inc.
