Learning graph in mach

> Can you elaborate on your alternative global variable suggestion, I am not sure I understood its link with https://github.com/JuliaAI/MLJBase.jl/pull/753 ? - In [`MLJBase.__init__`](https://github.com/JuliaAI/MLJBase.jl/blob/4d1ed14e7b1034fbe00c4dde3550144180da5225/src/init.jl#L1) add a new global constant -...

Emigration of one-dimensional range types

Comment to self: At present the first argument can have type `Model` for automatic inference of the type of the hyper-parameter. But the method is now also overloaded to accept...

Feature request: `pr_curve` convenience function to generate the precision-recall curve (PR curve)

For the record, the similar `roc` function lives [here](https://github.com/JuliaAI/MLJBase.jl/blob/dev/src/measures/roc.jl). I think it would make sense to implement the `AreaUnderPRCurve` measure as part of the same project (could be separate PR's)....

Feature request: `pr_curve` convenience function to generate the precision-recall curve (PR curve)

Thanks for letting me know, @adityasaini70 . By the way, a month is probably just fine, given this is a new feature and our other priorities. Good luck with the...

List of metrics in R and elsewhere, and which ones are implemented in MLJ

I've looked at the flux measures and I think their API is a little different because they want the measures to work on batches. And they only have a few....

List of metrics in R and elsewhere, and which ones are implemented in MLJ

Another to add to the list (looking ahead to image classfication) : Tversky Loss https://github.com/alan-turing-institute/MLJ.jl/issues/554

List of metrics in R and elsewhere, and which ones are implemented in MLJ

No, I think the most recent addition of metrics were the multiclass version of FScore and cousins. You can do `measures()` to list what is available.

List of metrics in R and elsewhere, and which ones are implemented in MLJ

Yep. We got this somewhere. @azev77 I'm currently performing a JuliaAI-wide issue review and collecting all issues in a GH project. All measure-related issues are being given a "measure" label...

Checking model instances are not types

I've made some progress here by adding a `check_ismodel` method to MLJBase #819 and implementing it for `Stack`. Left to do is to implement the check in: - [ ]...

Ensure packages implementing Code are threadsafe

I think some developers (myself included) will not too familiar with what is and what is not safe. Is there a list somewhere? (I know only this [discussion](https://discourse.julialang.org/t/whats-not-threadsafe/10984))
