Checking the Relevance of the Inputs (ASCMO-DYNAMIC)

During the data import you can check the relevance of the inputs for the outputs.

If you do so, a polynomial stepwise regression is done with the inputs and outputs. The stepwise regression ignores inputs with a significance < 5% and can find dependent inputs.

If, for example, the training data contains the inputs speed, load and speed + load, then one of the inputs has a low significance.

The order of the inputs is important. After the stepwise regression, the inputs are permuted column by column, and a pseudo RMSE is calculated per input, to get a heuristic of the input's relevance. The findings are then plotted in the "Relevance of Inputs" window.

To check the relevance of the inputs

  1. In the "Available Channels" field,

    Note  

    Only channels selected as inputs or outputs will be considered by the relevance check.

  2. Select Extras > Find Relevant Inputs.

    The "Relevance of Inputs" window opens. It visualizes the influence of the inputs on the outputs.

  3. Optionally: Click Show Table to display the results as a data table in the "Relevance of Inputs Table" window.

  4. Optionally: Refine your inputs and outputs selections based on the results.
