different tree for the same data set

Asked 2022-Feb-21 at 19:57

I am working on Pima Indians Diabetes Database in Weka. I noticed that for decision tree J48 the tree is smaller as compared to the Random Tree. I am unable to understand why it is like this? Thank you.

...

ANSWER

Answered 2022-Feb-21 at 19:57

Though they both are decision trees, they employ different algorithms for constructing the tree, which will (most likely) give you a different outcome:

J48 prunes the tree by default after it built its tree (Wikipedia).
RandomTree (when using default parameters) inspects a maximum of log2(num_attributes) attributes for generating splits.

Remove duplicates from a tuple

doc.ents is not a list of strings. It is a list of Span objects. When you print one, it prints its contents, but they are indeed individual objects, which is why set doesn't see they are duplicates. The clue to that is there are no quote marks in your print statement. If those were strings, you'd see quotation marks.

You should try using doc.words instead of doc.ents. If that doesn't work for you, for some reason, you can do:

What happens?

Code works well, but iterates to fast and elements your looking for are not present in the moment you try to find them.

How to fix?

Use selenium waits to check if elements are present in the DOM:

It's not very clear what is delta and df in your code. I am assuming they are the same data frame.

You can use the result from svm.predict , here we leave it as blank '' if not outlier:

How can I change the order of the attributes in Weka?

Asked 2021-Oct-08 at 00:07

I was doing a machine learning task in Weka and the dataset has 486 attributes. So, I wanted to do attribute selection using chi-square and it provides me ranked attributes like below:

Now, I also have a testing dataset and I have to make it compatible. But how can I reorder the test attributes in the same manner that can be compatible with the train set?

...

ANSWER

Answered 2021-Oct-08 at 00:07

Changing the order of attributes (e.g., when using the Ranker in conjunction with an attribute evaluator) will probably not have much influence on the performance of your classifier model (since all the attributes will stay in the dataset). Removing attributes, on the other hand, will more likely have an impact (for that, use subset evaluators).

If you want the ordering to get applied to the test set as well, then simply define your attribute selection search and evaluation schemes in the AttributeSelectedClassifier meta-classifier, instead of using the Attribute selection panel (that panel is more for exploration).
