init

TypeScript
static init(inputWindowSize: number, forecastWindowSize: number): LinearTimeSeriesForecasterConfiguration
Swift declaration
init(inputWindowSize: Int, forecastWindowSize: Int)

Creates a configuration. - Parameters: - inputWindowSize: The number of input samples. - forecastWindowSize: The number prediction samples.

inputWindowSize

TypeScript
get inputWindowSize(): number
Swift declaration
var inputWindowSize: Int

The number of input samples.

set · iOS 18.0+

inputWindowSize

TypeScript
set inputWindowSize(value: number)

maximumIterationCount

TypeScript
get maximumIterationCount(): number
Swift declaration
var maximumIterationCount: Int

The maximum number of allowed passes through the data. More passes over the data can result in a more accurately trained model. Consider increasing this if the training accuracy is low. Defaults to 25. - Note: This parameter is only used by the `fitted` method. When using the `update` method it's up to you to decide when to stop.

maximumIterationCount

TypeScript
set maximumIterationCount(value: number)
Swift declaration
var maximumIterationCount: Int

The maximum number of allowed passes through the data. More passes over the data can result in a more accurately trained model. Consider increasing this if the training accuracy is low. Defaults to 25. - Note: This parameter is only used by the `fitted` method. When using the `update` method it's up to you to decide when to stop.

earlyStoppingTolerance

TypeScript
get earlyStoppingTolerance(): number
Swift declaration
var earlyStoppingTolerance: Float

The early-stopping tolerance. The tolerance is used by the `fitted` method to decide when progress is no longer being made, in which case the training process will stop before the specified maximum number of iterations (known as early stopping). Significant progress happens when the validation loss decreases by at least the tolerance. Defaults to 0.01. - Note: Early stopping only happens when using the `fitted` method with validation data.

earlyStoppingTolerance

TypeScript
set earlyStoppingTolerance(value: number)
Swift declaration
var earlyStoppingTolerance: Float

The early-stopping tolerance. The tolerance is used by the `fitted` method to decide when progress is no longer being made, in which case the training process will stop before the specified maximum number of iterations (known as early stopping). Significant progress happens when the validation loss decreases by at least the tolerance. Defaults to 0.01. - Note: Early stopping only happens when using the `fitted` method with validation data.

earlyStoppingIterationCount

TypeScript
get earlyStoppingIterationCount(): number
Swift declaration
var earlyStoppingIterationCount: Int

The number of iterations to use when evaluating whether to stop early. The `fitted` method will stop if no significant progress is made for this many iterations. Significant progress happens when the validation error decreases by at least `convergenceThreshold`. - Note: Early stopping only happens when using the `fitted` method with validation data.

earlyStoppingIterationCount

TypeScript
set earlyStoppingIterationCount(value: number)
Swift declaration
var earlyStoppingIterationCount: Int

The number of iterations to use when evaluating whether to stop early. The `fitted` method will stop if no significant progress is made for this many iterations. Significant progress happens when the validation error decreases by at least `convergenceThreshold`. - Note: Early stopping only happens when using the `fitted` method with validation data.

batchSize

TypeScript
get batchSize(): number
Swift declaration
var batchSize: Int

The number of examples in each training batch. - Note: This parameter is only used by the `fitted` method.

set · iOS 18.0+

batchSize

TypeScript
set batchSize(value: number)
Swift declaration
var batchSize: Int

The number of examples in each training batch. - Note: This parameter is only used by the `fitted` method.
