In Orange3 while only using its widgets, without writing Python code, I’ve implemented the following typical machine learning processes
- Train a training set, (1 file)
- Validating a validation set (e.g. using Naiive Bayes and kNN), and
- Testing the model with a test set.(another file)
I keep getting:
test and train datasets have different target variables
error message. This is despite using exact same formats and names (with different values of course). What did I do wrong?
