At my work the SMOTE node is installed in SPSS Modeler. Unfortunately it doesn't do anything. When I look at the result-dataset the amount of churners/non-churners stays the same, no matter what kind of settings I choose. Do you know how to solve this? We use modeler 18.1.
Did you checked if you have the imbalanced-learn© Python library installed?

Greeting Everyone, I am a new one here.
I'm a brand new Modelica user. I'm trying to learn the language with OpenModelica. I'd like to use OpenHydraulics which is in github link in OpenModelica (specifically in the OMEdit Connection Editor).
I downloaded OpenModelica v1.19.2 and Modelica Standard Lib v3.2 to browse and run the library OpenHydraulics v1.0.1. However, when I open the Excavator example and try to Instantiate or Simulate the model I get many errors of the form:
[OpenHydraulics.Basic.VariableRestriction: 51:3-54:64]: Function ReynoldsNumber_m_flow not found in scope VariableRestriction.
Could you help me with this problem?
Thanks in advance.
there are a couple of things you need to take into consideration:
The current version of OpenHydraulics is still the original release from almost 10 years ago.
The library was developed using Dymola which at the time also supported a couple of non-standard Modelica, Dymola-specific constructs that other tools struggle to work with.
The example you are trying to run is the most complex one utilizing almost all of the power of the library and hence has quite a high degree of complexity.
Taking all this together means that OpenModelica is bound to struggle with that example. But all is not lost. If you actually look at the more simple circuit examples (under Circuit) you'll find that they work just fine. And depending on your application area they might already demonstrate a usage that will fit your needs.
I hope this helps.
Does anyone have experience converting Modelica 3.x files to the new 4.0 library standard? There is a link to a script, yet I am not sure how to apply it.
https://github.com/modelica/ModelicaStandardLibrary/blob/master/Modelica/Resources/Scripts/Conversion/ConvertModelica_from_3.2.3_to_4.0.0.mos
I am using Wolfram System Modeller 12.1 on a Mac, yet if needs must, can use OMEdit on either Mac or W10.
Any help to overcome my ignorance would be great.
Thanks for the help.
As far as I understand from discussion with developers conversion scripts aren't supported yet in Wolfram System Modeler.
I haven't heard as much about that topic from OMEdit, but the status seems similar based on https://github.com/OpenModelica/OpenModelica/issues/5297
The MSL 4.0.0 was even delayed a bit to give tools a bit of extra time to implement this feature. (That also allowed the scripts to be checked in additional ways with Dymola.)
I'm working on a eclipse-based model-based tool. I am not using UML/SysML but i created my own DSML (= component architecture, whereby components have a behavior, modeled using state automatons).
What I want to do now is to be able generate code and some config files from this model. So the question is: are there any good plugins out there, which would support that? (Tutorials wouldnt hurt either)
I did something similar in tool MPS (by jetbrains). It offers a string template language, that can be used for code gen. It would be cool to find something similar to it.
There is a plugin called StringTemplateDT in the eclipse market place. Does anyone have any experience with that?
best and thanks

Give JET (Java Emitter Template) a try, it was relatively easy to pick up.

I am working on an academic research regarding some very long functions in the Linux kernel (link, link).
For that research, I would like to use some code flow visualization tool, that would be able to plot a graph in which each vertex is a decision point and each edge is a piece of code which runs in a consequent way.
Do you know of any good, open source project that can visualize C code?
Perhaps a tool like KCacheGrind would be of help. It generates call graphs based on actual calls and cannot pre-generate a call graph without actually running the program, which may not suit your needs, but then it again it may.
History flow's are very neat for changes/diff across multiple versions.
Codeplex has a project, Dependency Visualizer which does support C also.
Gprof2Dot can render oprofile, this would get you dynamic info also.
CodeViz also (static tool) would work.
If your using gcc, gcc-xml has an introspector plugin also todo this.
You appears to want to acquire a flowchart of C source code ("decisions", "code blocks").
Something like this C flowchart?
To do this correctly, esp. for Linux kernal code, I'd expect you to have to preprocess the code first to get rid of macros and conditionals. I would assume that GCC would construct such a graph internally and that you ought to be able to get your hands on that graph.
Doxygen does some amount of 'visualization',
but you need to work on the code a bit for it to be usable.
Another interesting thing to check would be lxr
Linux Cross Referencer is a software toolset for indexing and presenting source code repositories. LXR was initially targeted at the Linux source code, but has proved usable for a wide range of software projects. lxr.linux.no is currently running an experimental fork of the LXR software.
I can recommend Sourcetrail. Can work with a compile_commands.json. Not sure if it's still maintained, though. But it's foss and you can fork it!
Being really new to wx, I'm wondering if there is an IDE (especially for Linux) which would help me lay out a frame or dialog or whatever just to help me see what I'm doing. That means also creating the code for those changes.
I remember way back when using resource compilers for OS/2 and Windows that produced binaries that would then create the window, and was hoping for something similar (though obviously not binary if wx doesn't support that).
I use wxFormBuilder. It is written in wxWidgets, so it works on Linux quite well. It can generate C++ code or XRC files. Make sure you understand its philosophy, and use it like this:
generate C++ code for the GUI
don't edit the code wxFormBuilder generated, but create new files
in new files, derive new classes from the classes it generated
implement event handlers in you own class (wxFB creates virtual function for each event handler you wish to use)
I usually name the wxFormBuilder generated classes/files like, for example, MainFrameGUI, and one with implementation (derived one in which I write all my code) would be just MainFrame. This enables you to change the visual layout and regenerate C++ files from wxFB at any time without overwriting your code.
DialogBlocks works quite well for me, although sometimes you need to edit the code to fix errors manually. It has a property editor that seems advanced enough.
Just another options is wxGlade. It does not have the that much features as the others mentioned seem to have, but it works just good enough for me to not daring to switch.
I use Code::Blocks IDE from http://www.codeblocks.org which has
- built-in GUI editor
- Cross compilable, so you can use it under Linux, OSX and Windows.
But I still use wxFormBuilder with it instead of built-in wxSmith editor. But they are compatible with internal wxSmith.
For windows you've got "wx-devcpp" which is Blodsheed Dev C++ with some addons providing what you looking for
