learning curves

Dear WEKA user,

I'm wondering whether using learning curves still considered to be good manner or there is any other better techniques?

Thanks in advance.
Jason

Relation-valued attributes

Hi all,

Anyone knows the advantage of using data that is consisted of relation-valued attributes generally?

Having such data in arff file can reduce the size of the file?

Thank you.

Andria

difference between naive Bayes and multinomial naive Bayes

Hi all,
for document classification purpose, 
1. what is exactly the difference between NB and MNB? 
2. why does MNB outperform the standard NB?

I need some formulas that show the difference!

Thanks

Computational Complexity

Hello, I was looking for papers discussing the computational complexity of the K* and Random Forest implementations in WEKA. Could you help point me in the right direction to find these, if they're available? Thanks,

David

Weka: When are datasets copied?

Let's say I have a dataset that occupies 70% of RAM. Now, obviously, if the dataset is copied, even just once, I overflow the heap space.

1. Which filters copy the dataset completely, without reusing parts of the old one? Do attribute filters do it (Add, Remove, etc.), and do instance filters do it (Sample, ...)?

2. When doing 10-fold cross validation, is the dataset copied 10 times? If so, is this a problem in practice?

Help To Enhance Classification Results

Dear all,

 

I have the following part of my arff file:

<at> attribute group {A,B,C,GEK}

<at> attribute ordera {0,1}

<at> attribute orderb {1,2,3,4}

<at> attribute Y1 {0,1}

 

And I used binary relevance method, this gave me low accuracy.

 

I would highly appreciate any suggestions in order to increase this accuracy.

 

Thanks.

Valerio

Estimators for HoeffdingTree

Dear Weka uers,

 

I have some problems with finding the suitable estimators for HoeffdingTree. I tried several but still have error message. Can anyone give me an advice about the good estimators for this scheme since I want to apply it on an incremental data.


 

Jason

bias factor

Hi everyone,

 

Is there any recommendation for the value of the bias factor with method such voted imbalance?


One more question, number of balanced datasets to be generated?

 

Thanks in advance

Keith

El Capitan Beta and Java Issue

The latest OS X operating system is the first to deprecate Java 6 and the current versions of Weka have significant issues running on El Capitan Beta 2. Is there any thought regarding a release that utilized Java 8?

I'd be happy to test if it would help.

Best,

Marc
