Hi Guys,
I realized that we don’t have a Linear interpolation node in KNIME. So, I made a simple one using a python inside a Component.

Just connect your dataset.
-
Select the columns you want to interpolate and the number of interpolations:
and Voila…!
NOTE: You can also see what happened with your data for verification:
Attached is the workflow.
Enjoy.

Also with minal changes in teh code you can also apply other interpolations such as:
| Type of Interpolation | Function Name |
|---|---|
| Polynomial Interpolation | BarycentricInterpolator |
| Polynomial Interpolation | KroghInterpolator |
| Univariate Spline Interpolation | UnivariateSpline |
| Interpolated Univariate Spline | InterpolatedUnivariateSpline |
| Least Squares Univariate Spline Interpolation | LSQUnivariateSpline |
| Cubic Spline Interpolation | CubicSpline |
| Rational Function Interpolation | RationalFunctionInterpolator |
| Piecewise Polynomial (PCHIP) | PchipInterpolator |
| Akima Interpolation | Akima1DInterpolator |
| Bivariate Spline for 2-D Data | RectBivariateSpline |
| Radial Basis Function Interpolation | Rbf |
| Nearest Neighbor Interpolation | NearestNDInterpolator |
| Multivariate Data Interpolation | griddata |
