# UpdatableTemporalEstimator A temporal estimator that can be incrementally updated. ``` protocol UpdatableTemporalEstimator : TemporalEstimator ``` ## Topics ### Appending [`func appending(_:)`](/documentation/CreateMLComponents/UpdatableTemporalEstimator/appending(_:)) Composes this updatable temporal estimator with an updatable supervised temporal estimator. ### Adapting [`func adaptedAsSupervised(annotationType: Annotation.Type) -> UpdatableTemporalEstimatorToSupervisedAdaptor`](/documentation/CreateMLComponents/UpdatableTemporalEstimator/adaptedAsSupervised(annotationType:)) Exposes this temporal estimator as a supervised temporal estimator. ### Encoding and decoding [`func encodeWithOptimizer(Self.Transformer, to: inout any EstimatorEncoder) throws`](/documentation/CreateMLComponents/UpdatableTemporalEstimator/encodeWithOptimizer(_:to:)) Encodes the transformer and optimizer to an encoder. [`func decodeWithOptimizer(from: inout any EstimatorDecoder) throws -> Self.Transformer`](/documentation/CreateMLComponents/UpdatableTemporalEstimator/decodeWithOptimizer(from:)) Reads the encoded transformer and optimizer with a decoder. ### Transforming [`func makeTransformer() -> Self.Transformer`](/documentation/CreateMLComponents/UpdatableTemporalEstimator/makeTransformer()) Creates a default-initialized transformer suitable for incremental fitting. [`func update(inout Self.Transformer, with: InputSequence, eventHandler: EventHandler?) async throws`](/documentation/CreateMLComponents/UpdatableTemporalEstimator/update(_:with:eventHandler:)) Updates a transformer with a new sequence of examples. [`func update(inout Self.Transformer, with: InputSequence) async throws`](/documentation/CreateMLComponents/UpdatableTemporalEstimator/update(_:with:)) ## Relationships ### Conforming Types [`UpdatableEstimatorToTemporalAdaptor`](/documentation/CreateMLComponents/UpdatableEstimatorToTemporalAdaptor) [`TemporalTransformerToUpdatableEstimatorAdaptor`](/documentation/CreateMLComponents/TemporalTransformerToUpdatableEstimatorAdaptor) [`PreprocessingUpdatableTemporalEstimator`](/documentation/CreateMLComponents/PreprocessingUpdatableTemporalEstimator) ### Inherits From [`TemporalEstimator`](/documentation/CreateMLComponents/TemporalEstimator) --- Copyright © 2026 Apple Inc.
