Function of a Sequence Notation ($s(\bar{\mathbf{y}}_1 \dots \bar{\mathbf{y}}_{k-1})$)

Evaluation Model for Predicted Sequences

Example of a Sequence of Predicted Future Values

An automated system is monitoring a factory machine's temperature. The current time step is recorded as $i=100$. The system uses a model to forecast the temperature for the next four time steps. Which of the following correctly represents the sequence of these four forecasted temperatures?

Interpreting Model Output

A forecasting model produces the term $\hat{y}_{i+t}$ as part of its output. Match each component of this notation to its correct description.
