now how to continue with the clustering modularisation
given all those dependencies. Maybe I shouldn't have started this,
because now I am stuck

Hello everyone. Is there, or gonna be, a dedicated ticket for the
modularisation of all 14 packages commons-math-legacy has? I think that
some of them are easy to modularise like optimisation, special and filter
Hello everyone. I am working on the modularisation of
the legacy ml.clustering package to a new module:
commons-math-clustering. Some clustering classes
depend on stat.moment.Variance and some of
the ml.distance classes.
1--those distances belong to geometry probably and
not machine learning. Manh
Hello everyone. Question about the clustering package.
I started moving the math4.ml.clustering package out
of math legacy to a new module comons-math-clustering.
There are some dependencies to legacy exceptions
and the distance subpackage. Is there a roadmap for how
to do this with instructions, T
module?
Where is the document with the precise requirements and instructions?

hello. I never said to redesign APIs. I only said that we can
move math algorithms from non-math projects, to the math projects

Hello everyone.
One thing i would love to do is to go through the apache projects, see
which ones already depend on the math library, and see if they implement
some math stuff that could be replaced by a call to commons math or move
that function to the math library. Would such cases be considered

Hello devs. I need a little help.
1--Say that I want to implement a new feature/function that, technically
exists in the math4 or legacy, but it doesn't exist in commons- geometry or
commons- numbers. What is the protocol? Do we create a ticket on math4 and
put the new code in math4 and ignore the

I just noticed that the line
return !isChecked(throwable)
Means that if throwable is null then it will be considered unchecked. I
will fix that tomorrow by doing
Return throwable ! null && throwable instanceof Exception;

Hello. I am a new contributor. Say I am working on a new public method
for a class, say, ExceptionUtils.java. What value do I put in
the @since field in the JavaDoc of this method?
Thank you for your time
