Hi,
I'll just ask on how to use the "Replace Missing Values" operator. After the Apply Model operator, I am dropping some predictions using "Drop Uncertain Predictions" leading to a "?" value on the prediction(class) attribute.
What I want to do is change this "?" to a different string. What I've done so far, which unfortunately is not working is the ff:
1. Use
Replace Missing Values operator
2. Set the attribute filter type to
"single" 3. On the attribute field, I inputted
"prediction(class)" 4. I ticked the
"include special attributes" check box
5. On the default field, i selected
"none". I also tried
"zero" and
"value". But none of them work as I expected
6. Edit the columns field and place prediction(calss) and value on the
"attribute" and
"replace with fields", respectively.
7. Under replinishment value, i placed there the string that will changed the "?" value. (e.g. "vague")
How should I do this? Your ideas are greatly appreciated.
Thank you!
