I want to use AdTree and BfTree algorithm on my datas but I could not find that algorithms in my Weka app. Is there anyone who knows to implement that to weka ?
Thank you so much.
In order to do that you have to open Weka and Select Tools > Package Manager.
On the "Package Manager" go to "Package Search" and look for:
"bestFirstTree" and
"AlternatingDecisionTrees" (Classification) or
"AlternatingModelTrees" (Regression).
Don't forget to select it (so it becomes blue) and then click Install !

I need to do some research in MDA/MDD to find Open-Source-Tools which will help me to develop code-generators and transformators.
But there are only a few tools which are actually supported. Do I search in the wrong direction?
Do You know open source tools for MDA/MDD?
Greetings Dominic
I found andromda, Eclipse Modelling Framework and a few tools like plantuml, which help to create diagrams .
My plan is to read diagrams with plantuml and convert them with emf to code and the reverse way.
Telosys could be a solution to your need (https://doc.telosys.org/)
Telosys has its own DSL to define the models (based on text files with a simple grammar), see https://doc.telosys.org/dsl-model
A Telosys model can be used to generate any kind of target language (including PlantUML) but Telosys cannot parse PlantUML files, so the input model must be a Telosys model (or a database schema if you create the model from a relational DB).
I have installed P360 10.1 from Informatica and want to try the new DQNavigation feature, where P360 jumps to the correct tab (WebUI) after clicking on a Quality Rule.
Unfortunately it seems that I do not use the right TabID (in: DQNavigationDefinition.XML). Does anybody use this feature already and knows which TabID I have to use (DebugID, Il18Nkey..)?
Huge thanks in advance!
After installing Weka 3.8, load a .csv file in the Explorer, I wanted to build a decision tree with the parameter "use training set".
Everything was installed ok (a self-extracting executable for 64-bit Windows that includes Oracle's 64-bit Java VM 1.8)
The file loaded fine as it was saved previously, using excel, as coma delimited.
The problem lays in building the decision tree itself: I go to the tab Classify, select the test option "use training set" and start.
After starting, appears a particular result which, accordingly to some images I've seen before, should allow, from there, to right-click and select "Visualize Tree".
That doesn't happen, as you can see in the next image:
How do I fix this in order to build the decision tree?
You have run a ZeroR classifier, see http://chem-eng.utoronto.ca/~datamining/dmc/zeror.htm. The ZeroR classifier is not a decission tree classifier and can not be visualised as such. You need to train an actual decission tree classifier, J48 is one of them. See http://facweb.cs.depaul.edu/mobasher/classes/ect584/WEKA/classify.html for a guide on how to do so.
I want to use some classification algorithm by weka(like c4.5, ID3) but I dont know how to add them to weka! Are they available on weka? and if these algorithm are not available how can I add them? And I could not find weka.classifiers.trees
package on google
Weka's implementation of C4.5 (and its precursor ID3) is called J48. J is for Java (and 48 is for 1998, or it is just some increment, I don't know).
Choose Weka Explorer, "Classify", "Classifier", "Tree" , "J48"
Click "More" Button:
NAME weka.classifiers.trees.J48
SYNOPSIS Class for generating a pruned or unpruned C4.5 decision tree.
For more information, see
Ross Quinlan (1993). C4.5: Programs for Machine Learning. Morgan
Kaufmann Publishers, San Mateo, CA.
Yes, they are available in weka,
As knb mentioned, we talk about J48 as if it’s synonymous with C4.5 and you dont need to download it.
In order to use ID3 classification algorithm you should download a package named "simpleEducationalLearningSchemes".

How do I save an ERD in Toad for Oracle as a .txp file or any other format that I can open in Toad Data Modeler?
I have tried to find a way to open the .erx files I have in TDM but it doesn't work that way.
Thank you
I have been looking for a way to do this for a very long time (about a year now) and it would appear that it just cannot happen.
No need to save it differently if you are using version 6.4. Simply select the Import from the File menu and Reverse Engineering wizard will take it from there.
