How to import samples

Sample file csv layout

An example file is located here. It consists of 5 columns. Columns x1 through x4 are the input columns and column y is the value returned from the 4D spherical function.

In general the csv file must contain a single header row with the names of the input parameters and all outputs. Each run of the model/function is a row in the file. All inputs and outputs must be scalar values.


These instructions reference the csv file located here. This file contains 120 samples of the 4D spherical function. The inputs are labeled x1 through x4 and the function value is in the column y.

  1. Click on the 'New Project' button in the project browser Responsive image
  2. Fill out the dialog box as shown. It is important that the input names and ranges match those in the csv file Responsive image
  3. Click the next button. Responsive image

  5. Click the "Run" button which will build the GP model. Responsive image
  6. Once the GP model is done building the response selector dialog will appear. There is an option for each output, whether you want to minimize, maximize or ignore it. For the spherical function we want to minimize it. Then click the "Ok" button which will open the main Tuner project window. Responsive image
  7. By default, no response is selected. To select the response, click the controls tab. Then in the "Response 1" combo box, select "y" as the output.
