Open Source: sustainability and etiquette
by Reshama Shaikh Oct. 11, 2021

Oct. 11, 2021

Hello, I've seen some excellent resources that have explained open source, its sustainability, challenges and *indirectly, the etiquette*. I am starting to compile the list here [a]. This keynote by Stuart Geiger is a must-watch: The Invisible Work of Maintaining & Sustaining Open Source Software [b] There is one more video by Emily someone who was at Microsoft, but is now a professor somewhere, and I am trying to track that video down. I think it's from 2017. I'll add it to the list once I find it. If anyone knows the full name of the speaker, please share.

by Gael Varoquaux Oct. 5, 2021

Oct. 5, 2021

This email is meant for the scikit-learn Technical Committee, and is on the public mailing list for transparency. The community has not been able to reach a strong consensus on an incredibly important decision: line length :) https://doodle.com/poll/wpp7c8343zy46v93?utm_source=poll&utm_medium=link So, the TCs need to make a vote. Members of the TC, please vote below by adding your name: Keep current 88 characters: Revert to 79 characters: As a reminder, the technical committee is made of: Alexandre Gramfort, Olivier Grisel, Adrin Jalali, Andreas Müller, Joel Nothman, Hanmin Qin, Gaël Varoquaux, and Roman Yurchak (according to https://scikit-learn.org/stable/governance.html) We have one week to vote, but if we do it in less time, no one will complain. Thanks! Gaël -- Gael Varoquaux Research Director, INRIA Visiting professor, McGill http://gael-varoquaux.info http://twitter.com/GaelVaroquaux

Spanish translation proposal for Scikit-Learn documentation
by Mariangela Petrizzo Aug. 17, 2021

Aug. 17, 2021

Dear Scikit-Learn team! I am Mariángela Petrizzo, I am writing to you as a member of Qu4nt, a team dedicated to the use of open source tools for the development of software solutions with emphasis on data science. We have a strong interest in translating the Scikit-Learn documentation into Spanish. Our team is made up of members from various scientific fields, including some university faculty in linguistics and computer sciences, with a wide experience in Python as well as several libraries used for data analysis and machine learning, and also contribute locally as evangelists of its use in Spanish-speaking communities, in particular, the leader initiated the translation of some Software Carpentry lessons into Spanish. That is why we have been discussing the opportunity to offer our contribution to the Python project, promoting the translation into Spanish of the documentation of some of the libraries with the greatest impact in our areas of interest. Talking with David Mertz, to whom we are sending a copy of this email, we have explored options, and the idea of working with Scikit-learn has really seemed to be an exceptional opportunity for all of us and the community. He's very enthusiastic about the idea of generating a spanish translation of Scientific Python libraries like Scikit-learn. For us, this translation project has to be done through a completely open work on Github, taking as reference the restructured text sources for Sphinx from a git fork, using the tools provided by Sphinx itself for internationalization: https://www.sphinx-doc.org/en/1.8/intl.html, and applying tags to perform planned updates. In addition, as with any open source project, the main mechanism for quality assurance comes from the users themselves who will have the channels available for submitting issues. Our intention is to secure all the infrastructure and mechanisms to make this possible: making the process transparent through Github, using as much as possible tools like Transifex to facilitate participation, and providing guidelines for contributors as part of the project. Of course, this project cannot be realized without your support. We therefore come to you to inquire about your willingness to accompany and support this project. We would love to hear your feedback on our proposal.

random forests and multil-class probability
by Sole Galli Aug. 14, 2021

Aug. 14, 2021

Hello community, Do I understand correctly that Random Forests are trained as a 1 vs rest when the target has more than 2 classes? Say the target takes values 0, 1 and 2, then the model would train 3 estimators 1 per class under the hood?. The predict_proba output is an array with 3 columns, containing the probability of each class. If it is 1 vs rest. am I correct to assume that the sum of the probabilities for the 3 classes should not necessarily add up to 1? are they normalized? how is it done so that they do add up to 1? Thank you Sole

[Data Umbrella] scikit-learn Latin America sprint (June 2021)
by Reshama Shaikh July 28, 2021

July 28, 2021

Hello, Data Umbrella is organizing a scikit-learn open source sprint, with a focus on * LATIN AMERICA * on June 26, 2021. This scikit-learn sprint is a 4-hour online hands-on "hackathon" where we work on issues in the scikit-learn GitHub repo to get started in contributing to open source in a structured setting. There is 2-3 hours of pre-work and participants will work with a pair programming partner during the sprint. Sprint website: https://latam2021.dataumbrella.org/home Sprint application: https://forms.gle/cxav9eE9ZkiULfbm7 Tweet: https://twitter.com/DataUmbrella/status/1394661734275821573 LinkedIn post: https://www.linkedin.com/feed/update/urn:li:activity:6800434144624070656/ Meetup event: https://www.meetup.com/data-umbrella/events/278298428/ FAQ: Q: If I am not in Latin America, can I still apply and participate? A: Priority will be given to folks in the Latin America region. If there are open spots, we will open it up to other regions. In the meantime, we have resources available for all to get started in contributing to scikit-learn. Check them out here: https://latam2021.dataumbrella.org/about/prep-work Any questions, please email us: data.umbrella.dei(a)gmail.com Cheers, Reshama --- Reshama Shaikh she/her Blog <https://reshamas.github.io> | Twitter <https://twitter.com/reshamas> | LinkedIn <https://www.linkedin.com/in/reshamas/> | GitHub <https://github.com/reshamas> Data Umbrella <https://www.dataumbrella.org> NYC PyLadies <https://meet.meetup.com/wf/click?upn=pEEcc35imY7Cq0tG1vyTt6zEs68RbcMfjPcajN…>
