Binary prediction - surely it can't work if it needs a Y/N field as they default to a value?

I'm trying to set up a binary prediction as the number prediction just does nothing. It doesn't create the output columns in the table.

But the binary prediction seems to want a Yes/No field. But a Yes/No field has a default value, so you end up with a value in every field by default. As a result there are no blanks to predict.

So there is no way this can actually work is there?

I figured it out. Lack of Dataverse knowledge. You can create a Yes/No but as long as you don't interact with the cell it won't default to a value. At least I have the model to the point of training. If it goes like it did for the numerical prediction it won't actually create columns with predictions, but I hope it will.

And it won't publish. Of course. Does this AI Builder actually work? This thing seems really random. I have had issues with publishing before where it won't but the next day it does.

Your output variable is yes/no? Based on your input data, you want to predict yes/no out column?

It's now the next morning (Australia) and it publishes. I did not change anything overnight.

It has created a column called cr189_islateyesno - predicted (Prediction 18/11/20 but it has no values.

My input column is IsLateYesNo and is a Yes/No field. It was edited in Excel and has some blank values in it.

However there has been nothing written into the prediction column?

Yes the prediction column is a yes/no, and the outcome I am looking for is a yes/no.

Here is a screenshot of some data. I am not giving it a lot, but it is giving me an r-squared of B so I assume it can predict something. But it is not writing the prediction into the prediction column?
