weka-3.8's Issues

cannot select J48 in classify for latest weka

Dear developer,
I am a new-comer for weka. And I have just installed weka 3.8.3 for windows 64bits.
After I installed it and opened a new file, I wanna classify it with decision tree (J48).
But I found the column is not able to click.
Could you give me some suggestion on how to deal with this issue?

Cannot build weka-3.8

Weka Warning

Hi,

When train to build and run my Weka model (from the Java API) without the mtj dependency, I get the folling error:

WARNING: core mtj jar files are not available as resources to this classloader (sun.misc.Launcher$AppClassLoader@18b4aac2)

My question is whether prior warning and non-inclusion of the mentioned library affects the correctness of code execution or only its performance?
If it affects performance, how much?

Thanks in advance,
Milan

Glitches upon the closure(destory) of a window in macOS 11.4

Environment: macOS 11.4 (20F71)
Weka version: weka 3.8.5 (1.0)

I think this problem is UI related, please fix it, it deducts the user experience. It happens on my machine, I am not sure for other system like Windows.

Recurrence

Open any one window that in applications and close it, the window will be frozen but still be displaying on the screen.

Screen.Recording.2021-07-07.at.6.40.44.PM.mov

And when opening a new application window, the previous one that has been closed will disappear(be destoryed).

It seems to be a new window is invoked, the previous one is destoryed to some custom java windows. The LogWindow totally has not a problem related to this, and the LogWindow can only have one instance, instead of like that can hold multiple Package Manager, which confused me. (Logically I do think the Package Manager shoulld have only one instance, also for some other utils)

Same thing happens to the other window in Tools. The Memory usage window also has this problem.

Analysis

There must be some logical problems with the closure confirming.

Firstly, some of windows should not have multiple windows, there's no reason for it, like Package Manager or Meomry usage.

The problem occurs in any window that can have multiple instances, and they all go with a closure confirming window, like this:

The LogWindow only has one instance, it will be closed immidiately when click the close button. The open file window has no confirm and it will close immediately as well. As shwon in the screen recording above, when close a window but the window is still upon the screen, create an arbitrary window will ensure the closed window is "destoryed". To clarify, the arbitrary window can be another application, or LogWindow, etc. and the closure confirming window is counted among it, and the screenshot below is a "About GUIChosser" window, that works as well. (I think this window might be different from the Windows.)

Another one is, when close a window and it has not been destoryed, switch to other apps and switch back, it might be destoryed by then. It happens sometimes. If it still exists there, click the button to close again it may close immediately or create a new window to have the same effect.

Workaround

Create any new window can destory a closed window. If create a new window that does not have the closure confirming then we can close the new window immediately.

Search by text in filters frame

Dear developers,
I have been using Weka by GUI, i would suggest you to add a text search to the frame used to select filters.

This could really improve the usability of the app.

Version 3.8.5

implementing my clusterer

Hello, I'm new here, and I'm trying to implement a BDSCAN algo for clustering string and date type attributes.

I overided buildClusterer(), numberOfClusters(), clusterInstance() and getCapabilities().
I stored into a hashmap<Instance, Integer> to know which cluster every Instance is attributed to so I can call it in clusterInstance().
I still don't know what correspond the prior probability of clusterPriors() and everything about logDensityPerClusterForInstance(), so left it as return null but I tried to hardcode it also but it doesn't change my issue.

So when I'm running my code, I got this:
=== Clustering stats for training data ===
Clustered Instances
Unclustered Instances : 1799
Log likelihood: NaN

weka.filters.unsupervised.attribute.RandomSubset not using numAttribute variable

When using RandomSubset I found that when trying to remove an amount of attributes (proportion %) it always defaults to 50% no matter the input.

Console output:

Weka 3.8.3 .dmg file fails to mount

Hello,
I am trying to install Weka 3.8.3 to my macbook which is running on osX v10.11.6 El Capitan and the dmg file fails to mount (no mountable filesystems).

Weka 3.6.15 gets installed without any problems though.
Could you please check?

Thank you

Logistic regression/ DT/RF Under the hood dealing with missing values WEKA

Hello. Iam trying to implement some algorithms defined in a paper which used weka software, but mine must be implemented in python. Python does not deal with missing values, in contrary to weka. Iam asking what do logistic regression, decision tree, random forest under the hood so that they run without throwing error about missing values

"git clone weka" and "java run" in terminal?

Can't i just "git clone weka" into some local repository of mine and run it in any terminal i open? It would be easier to use weka, because every update we would know and could simply make "git pull". Is somehow possible to do it?

Program name and publisher name missing in weka-3.8.4
