Uses functionality provided in a Jupyter notebook to embed documents from a topic-space representation into 2D Euclidean space. The embedding is done using scikit-learn's implementation of the t-SNE algorithm.
The Jupyter Notebook seemingly did not make it into the final workflow, but it should be this one:
And also if one would put it into a subfolder in the workflow the relative KNIME path should look something like this:
