Feed Embeddings to autoML node

Hi,

I want to try to train the following workflow model

However, I encounter a challenge. In my CSV file, there’s a column containing arrays (embeddings) that I need to input into the AutoML node:

Could you please guide me on how to accomplish this task?

Thank you.

Hi @mee888 and welcome to the forum.

Seems like you need to do some preprocessing on your embeddings first, since they are being imported into KNIME from your CSVs as strings.

I would try a String Cleaner to get rid of the brackets, followed by a Split Collection Column on spaces, then some type conversion to doubles, followed by a Create Collection Column to get a proper KNIME collection.

Uploading a data sample for us to play with would be helpful.
