Can anyone let me know how to solve the problem with my predictor node which shows the error that “Learning column XXX not found in the input data to be predicted”.
I have created a model for text processing and then used decision tree to train the model to categorize the documents into two categories. The first part has worked perfectly with 98.9% accuracy. However, when i wanted to use the same learning model on new data it is showing error as described above.
Can anyone please help me to solve this issue.
I am sharing a link to download my KNIME workflow.
Look forward to replies.
