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:

Hello @EnzoSalvi
Are these weights used to select attributes? If so, you can use "Select by weights operator.0 -
Thank you, seems I'm getting the right way. Just another question, is there a way to firstly assign weights "automatically" (ex: by correlation, information gained, deviation etc.) and then apply my custom weights? Thank you in advance.

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.0
