struct TimeSeriesForecasterAnnotatedWindows<Scalar> where Scalar : MLShapedArrayScalar

A sequence of forecasting windows on a time series shaped array. A time-series forecaster takes a series of samples and produces a prediction of the next samples. For example the sequence `[1, 2, 3, 4]` could predict `[5, 6]`. The shape of each feature in the sequence is `[inputWindowSize, featureSize]` and the shape of each annotation is `[forecastWindowSize, annotationSize]`. The sequence will return as many feature-annotation examples as fit in the input. For example an input sequence of size of 10 with an input sample count of 4, a prediction sample count of 2, and a stride of 1 will produce 5 annotated windows: ``` feature: [1, 2, 3, 4], annotation: [5, 6] feature: [2, 3, 4, 5], annotation: [6, 7] feature: [3, 4, 5, 6], annotation: [7, 8] feature: [4, 5, 6, 7], annotation: [8, 9] feature: [5, 6, 7, 8], annotation: [9, 10] ``` Note that 9 and 10 are never used as features because there would be no annotations for those samples.
