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