Metadata Routing Survey
by Adrin Jan. 27, 2022

Jan. 27, 2022

Hi there, We're in the process of hopefully finalizing the user and developer API for metadata routing, and we'd like to hear your thoughts on a few things, especially if you're somebody who develops custom/third party scikit-learn compatible estimators. You can find the survey here <https://docs.google.com/forms/d/e/1FAIpQLSd8G8xwKKJ2gJKmqcyZafi6z3mMQdDDiHf…>. It'll take just a few minutes, and it would really help us finalize the work and have it ready sooner for you to benefit from it. Regards, Adrin

Using KernelDensity for spatial clustering
by Mahmood Naderan Jan. 25, 2022

Jan. 25, 2022

Hi I would like to group a set of numbers by their spatial distance and since it is a 1D problem, I want to use KernelDensity. Based on the examples I saw in the internet [1], the following code, works: a = array([1,2,3,10,12,11,50,51,52,53]).reshape(-1, 1) kde = KernelDensity(kernel='gaussian').fit(a) s = linspace(0,100) e = kde.score_samples(s.reshape(-1,1)) mi = argrelextrema(e, np.less)[0] With the code, I am able to find the minima of the KDE and then compare the values in `a` with `s[mi]`. For simple and test file, that works. However, I need some more information about the way it works. For example, if I change the linespace boundries, the result changes. What does the linespace do exactly? [1] https://scikit-learn.org/stable/auto_examples/neighbors/plot_kde_1d.html Regards, Mahmood

Upcoming: 2nd edition of "Machine learning with scikit-learn MOOC"
by Gael Varoquaux Jan. 23, 2022

Jan. 23, 2022

Hi everyone, The team at Inria, with the help of the Inria learning lab, will soon be opening the 2nd edition of the "Machine Learning with scikit-learn" MOOC: https://www.fun-mooc.fr/en/courses/machine-learning-python-scikit-learn/ The content of the MOOC is visible here (we are still polishing details, this is not final): https://inria.github.io/scikit-learn-mooc/ As you can see, it touches all the basics of machine learning, introduced with scikit-learn, teaching much more than the API of the library. We have put a lot of effort on being didactic. Anna Kondratenko, one of last year's participant, said of last year's edition: "I did a #ScikitLearnMooc course as part of a #100DaysOfCode challenge and I just loved it. Scikit-learn creators managed to make it practice-focused and entertaining at the same time. Also, it is perfect for beginners since it starts from the basics going to more advanced level." https://twitter.com/anacoding/status/1484949583629369344 This year's edition should be significantly more didactic! One of the values of participating to the MOOC, compared to just the material that we provide on the web, is that it is full of coding exercise, that are meant to teach understanding of machine-learning and coding skills. The MOOC is absolutely free, and all the materials are open (in the spirit of scikit-learn). While many people on this list may already know the contents of this MOOC (though, we have inserted many useful reflections), you might know people who could benefit from this course to learn machine learning. Please help us spread the word. Pythonly yours, Gaël -- Gael Varoquaux Research Director, INRIA http://gael-varoquaux.info http://twitter.com/GaelVaroquaux

VOTE: SLEP006 - Metadata Routing
by Adrin Jan. 21, 2022

Jan. 21, 2022

Hi there, We're calling a vote <https://github.com/scikit-learn/enhancement_proposals/pull/65> on SLEP006 - Metadata Routing, which is available here <https://scikit-learn-enhancement-proposals.readthedocs.io/en/latest/slep006…>, and detailed past discussions can be found under these PRs <https://github.com/scikit-learn/enhancement_proposals/pulls?q=is%3Apr++slep…> and these issues <https://github.com/scikit-learn/enhancement_proposals/issues?q=is%3Aissue+s…> . The current proposed implementation is drafted under this pull request <https://github.com/scikit-learn/scikit-learn/pull/22083> where you can find a rendered version of the user guide here <https://171332-843222-gh.circle-artifacts.com/0/doc/metadata_routing.html> and a rendered version of the developer API (only applicable to third party developers and people who write custom estimators) here <https://171332-843222-gh.circle-artifacts.com/0/doc/auto_examples/plot_meta…>. These are found under `metadata_routing.rst` and `plot_metadata_routing.py` under the aforementioned PR <https://github.com/scikit-learn/scikit-learn/pull/22083> respectively. Note that this PR does NOT touch scorers, splitters, or any of the estimators or meta-estimators in scikit-learn. It implements the machinery in `BaseEstimator` for *consumers* only. The PR is also not targeted to `main`, and instead it's to be merged into the `sample-props` branch on the main repo, with follow-up PRs to complete the implementation before merging into `main`. Please leave your votes here in the PR <https://github.com/scikit-learn/enhancement_proposals/pull/65>, and comment on the PR, here on the mailing list, or open new PRs/issues in the enhancement proposals repo or the main repo for specifics if you think further discussion is required. Note that this vote is not to merge the implementation PR, and is rather to accept the SLEP, and the SLEP does NOT discuss implementation details and the API for us and third party developers; but we're more than happy to discuss the implementation and the API during this voting round. We also plan to send out a survey asking third party developers for their opinion of our proposed developer API, parallel to this call for vote. This vote will close on February 21, 2022, and per our governance model it will pass if 2/3 of the cast vote from core developers are in favor, with no quorum/minimum participation requirements. Regards, Adrin
