DOC update reductions user guide

[hildeweerts]

There is some useful information in the credit loan decisions example notebook that should be integrated in the reductions user guide.

it would be really useful to have the information from the Credit loan decisions example notebook in the ExponentiatedGradient user guide entry.

If this issue is still open may I work on it?

@sanvi0sh do you know what to do for this one? I'm afraid it's not super well-defined and leaves a lot of room for interpretation. There are other issues that don't have that problem in case you're open to others.

You can certainly read the notebook and send a brief list of things that should go into the user guide, so that one of @fairlearn/fairlearn-maintainers can confirm or chime in.

i was hoping one of the maintainers would explain me further on what to do once i was assigned the issue but thanks for letting me know. i'll give the user guide and comment here about the changes that seem apt to me.

[romanlutz]

@sanvi0sh that is not at all an unreasonable assumption. Other issues with "help wanted" are usually more clearly scoped. Feel free to look at them if you don't want to look i to a more open-ended one like this.

[hildeweerts]

hi @ciaokitty! Are you still interested in working on this? If you are, let us know if you have any questions! If not, that is of course not a problem either, but then we know the issue is still open for somebody else to pick up.

Hello @hildeweerts and @romanlutz! Since I don't see any updates on this issue, can I work on it?

[romanlutz]

Sure, but I still suggest reading through the notebook first and suggesting additions to the user guide before actually creating a PR. Otherwise you may end up doing work and then get told that it requires a lot of changes.

Other issues are better scoped, so this requires some of that work upfront. Of course, you may also start with another issue marked with "help wanted" if you prefer. This is not a straightforward one.

[Hrittik20]

Okay, but I have already tried doing it. So can you take a look at it once and let me know what you think?

[romanlutz]

We should get @MiroDudik's take on this since he's one of the authors of the paper.

@Hrittik20 -- this is a good start. If you're still interested, please start a PR. The main additional content to add is the part about actually exploring the performance-fairness trade-off by examining the inner models returned by this function. Happy to help guide you further.
