Give custom weights to my ExampleSet
Hi. I am trying to run a decision tree algorithm on my dataset, which is highly "inaccurate" and "weak".
To solve this problem, I want to assign custom weights to my features but I don't know how to achieve that.
I found the "Weight by user specification" operator, which gives "weights" as output. What operator should get the weights object as input? How can I tell to my process that these weights are related to the ExampleSet?
This is my current situation:

Yes, you can, search the operator's tab with "weight" as a keyword, you have many ways there. Here is the image taht shows some available operators.
Hope this helps.
Hope this helps.
Are these weights used to select attributes? If so, you can use "Select by weights operator.
