# UpdatableEstimator Implementations ## Topics ### Instance Methods [`func decodeWithOptimizer(from: inout any EstimatorDecoder) throws -> StandardScaler.Transformer`](/documentation/CreateMLComponents/StandardScaler/decodeWithOptimizer(from:)) Reads the encoded transformer with a decoder. [`func encodeWithOptimizer(StandardScaler.Transformer, to: inout any EstimatorEncoder) throws`](/documentation/CreateMLComponents/StandardScaler/encodeWithOptimizer(_:to:)) Encodes the transformer to an encoder. [`func makeTransformer() -> StandardScaler.Transformer`](/documentation/CreateMLComponents/StandardScaler/makeTransformer()) Creates a default-initialized transformer suitable for incremental fitting. [`func update(inout StandardScaler.Transformer, with: some Sequence, eventHandler: EventHandler?)`](/documentation/CreateMLComponents/StandardScaler/update(_:with:eventHandler:)) Updates a transformer with a new sequence of examples. --- Copyright © 2026 Apple Inc.
