Hello. I’d like to know if it’s possible in KNIME to learn a non-linear regression model that is capable of dealing with categorical variables. More specifically, my problem has the following variables:

Input variables:

- Position in the plate with 5 levels (categorical):

- Top left
- Top right
- Center
- Bottom left
- Bottom right

- Orientation with 4 levels (categorical):

- YZ
- ZY
- YZ45
- Y45Z

- Thickness (double)
- Energy density (integer)
- Pressure (double)
- Number of times reused (integer)

Output:

Mechanical resistance of the piece
