Using Vectors deriving from BERT Embedder inside a linear regression learner

[aworker]

Hi @rickybordon & welcome to the KNIME community forum

As mentioned by @Daniel_Weikert, you most probably can split your column of “vector-like” type into separated columns, for instance using the -Split Collection Column- node.

The following workflow shows how to do it on a column of type bit vector (but the node can normally split any type of vector data):

Similarity matrix (Tanimoto)

Hi @adesinoh and welcome to the KNIME community ! Below you will find a workflow which provides a full Tanimoto matrix distance: [image] 20220216 Pikairos Tanimoto Similarity Matrix.knwf (110.1 KB) The extra work needed here was to transform a Half-Diagonal Distance matrix provided by the -Distance Matrix Calculate- node into a full Distance Matrix with “Ones” diagonal included. This can be generalized to a Euclidean Distance Matrix where the diagonal should be made of Zeros. Hope it help…

If this example doesn’t help, please upload here an example of your data on a KNIME workflow so that we can take the problem from there and help you further.

Best,
