Abstract
Embodiments describing an approach to aligning multiple time series. Calculating an indicator function. Estimating a coefficient vector based on the indicator function. Updating the coefficient vector. Determining if a change in the coefficient vector is less than a predetermined value, and responsive to determining the change in the coefficient vector is less than the predetermined value, outputting a target time series for controlling aluminum smelting.
Claims20
A method for optimizing aluminum smelting control, the method comprising:
- aligning, by one or more processors, multiple time series;
- calculating, by the one or more processors, an indicator function;
- estimating, by the one or more processors, a coefficient vector based on the indicator function;
- updating, by the one or more processors, the coefficient vector;
- determining, by the one or more processors, if a change in the coefficient vector is less than a predetermined value;
- and
- responsive to determining the change in the coefficient vector is less than the predetermined value, outputting, by the one or more processors, a target time series for controlling aluminum smelting.
