GaussianMixture - proposed features
by Ehud Schreiber Nov. 29, 2025

Nov. 29, 2025

Hi, I'd like to propose a couple of features that, as a user, I believe may be useful for Gaussian mixture modeling with GaussianMixture. I don't see how to currently do them, and I think they should be quite easy to implement, but I may be wrong. 1. The weights of the components may be known. In that case, we would like to provide them through weights_init, but then they should be frozen and not optimized by the EM steps. So perhaps a frozen_weights boolean parameter, relevant only when weights_init is not None? 2. In covariance_type, there are the full/diag/spherical options, but I think that logically "tied" is independent - currently it's "tied full", but there could just as well be "tied diag" and even "tied spherical" with only a single parameter for the variances. So I propose having two input parameters allowing for 3*2 = 6 structures instead of the current 4. Thanks for all your great work for the community, Ehud Schreiber.

Hi all, During today's November project meeting, we did not have time to cover all the important topics on the agenda, so we decided to move the December meeting ahead by two weeks. This move also has the side benefit of having the December meeting before the end-of-year holiday season. The project calendar has been updated accordingly: https://blog.scikit-learn.org/calendar/ Cheers, -- Olivier

scikit-learn: mailing list is now in moderator mode
by Reshama Shaikh Oct. 4, 2025

Oct. 4, 2025

Hi Everyone, As you may have observed, this mailing list has received a bit of disruptive spam in recent months. For that reason, the mailing list settings have been updated to require a moderator approval before posting to the entire distribution list. If you submit a message, it will not be immediately delivered until a moderator approves it. There are a few moderators on this list, and we aim to approve posts within a week. It will not be necessary to submit multiple messages to the mailing list; there will be a modest delay. Thank you for your patience, and we aspire to manage this space in our digital world with reduced spam. Kind regards, Reshama --- Reshama Shaikh

when fold is not an integer, how does refit work?
by Sole Galli Sept. 19, 2025

Sept. 19, 2025

Hey team, In RandomisedSearchCV or SuccessiveHalving, we can pass indexes in the fold parameter, if we want to test the hyperparameters on specific folds. Say I have a dataset of 12 rows, indexes 1 to 12, and I pass as fold to the randomized search or SH the following folds: [1,2] [9, 10, 11, 12] [3, 10] [5,6,7,8] [7, 11] [1,2,3,4] It will use [1,2], [3,10] and [7,11] to train the model, and the second part with the 4 rows as the test set. My question is, when refit=True, what does it use to train the final model? X? the sum of the training folds? the sum of the test folds? something else? It's a follow up question to this reply on SO: [https://stackoverflow.com/questions/79748461/how-to-pass-pre-computed-folds… Thanks a lot! Best wishes, Soledad Galli https://www.trainindata.com/

Exploring the World of Anonymous Chat !
by level.orangutan.npab＠rapidletter.net Sept. 11, 2025

Sept. 11, 2025

In today’s digitally connected world, meeting new people online has become easier and more spontaneous than ever before. Anonymous chat platforms offer a unique way to strike up conversations with strangers without revealing your identity. Among these platforms, Omegle stands out as one of the most popular and straightforward ways to engage in anonymous chats. Whether you’re looking to kill time, practice a language, or just connect with someone new, an anonymous chat can be an intriguing experience. In this article, we’ll take a closer look at how to play or experience an interesting anonymous chat platform like Omegle, share some handy tips, and discuss what to expect along the way. Introduction: What is Omegle and Why Try Anonymous Chat? https://omegleweb.io Omegle is a free online platform that connects random users worldwide for text or video chats. Launched back in 2009, it gained popularity due to its simplicity and the thrill of chatting anonymously with strangers. You don’t need to sign up or create a profile, which removes many social barriers and opens the door to spontaneous, genuine conversations. Anonymous chat platforms can be both fun and eye-opening. They offer a way to step outside your usual social circles and meet people from different backgrounds and cultures. Using Omegle, or similar services, you can exchange ideas, learn about new perspectives, or just enjoy a random chat without pressure. For those interested, you can try it out yourself by visiting Omegle. Gameplay: How to Use Omegle for an Interesting Chat Experience Getting started on Omegle is as easy as it gets. Here’s a simple guide on how to jump into an anonymous conversation: 1. Visit the Website: You can use Omegle directly via its official web page or through other platforms that host the service. The interface is very minimalistic, so it won’t overwhelm you. 2. Choose Your Chat Mode: Omegle offers primarily two modes – text chat and video chat. The text chat pairs you with a random stranger, where you can type messages back and forth. The video chat mode connects you for live video conversation. 3. Optional Interests: Before starting, Omegle allows you to enter interests or topics you’re curious about, like “music,” “travel,” or “books.” This helps the platform match you with someone who shares those interests, making conversations more engaging. 4. Start Chatting: Once you hit the start button, Omegle pairs you with a random stranger. Conversations can last as long as you both want, or you can end and find a new partner anytime you feel like it. 5. Stay Anonymous: By default, Omegle keeps your identity hidden. You don’t have to share your name or any personal information unless you choose to. 6. End or Skip Conversations: An important feature is the option to stop chatting at any moment or skip to a new partner if the conversation isn’t going the way you expected. Tips for a Safe and Enjoyable Experience While anonymous chat is exciting, it’s important to navigate it wisely. Here are some practical tips to help you have a better and safer experience on Omegle or similar platforms: • Protect Your Privacy: Avoid sharing personal details like your real name, address, phone number, or social media accounts. You never know who you are chatting with, so keeping your identity protected is essential. • Be Polite and Respectful: Remember that the person on the other side is also human. Politeness and respect can make the interaction enjoyable for both of you, even if the conversation is short. • Use Interests to Your Advantage: Adding interests when starting a chat can lead to more meaningful and relevant discussions instead of random, off-topic messages. • Handle Awkward Moments Gracefully: Since conversations are anonymous and random, you might encounter awkward or strange exchanges. If someone behaves inappropriately, don’t hesitate to end the chat immediately. • Manage Expectations: Not every conversation will be deep or meaningful. Sometimes you’ll hit it off, other times it’s just passing time. Approach the experience with an open mind and a sense of humor. • Avoid Video If You’re Not Comfortable: While video chatting can feel more personal, it’s not for everyone. Start with text chat until you feel comfortable, and never feel pressured to turn on your camera. • Report Inappropriate Behavior: If you encounter harassment or suspicious activity, most platforms have ways to report it. This helps keep the environment safer for everyone. Conclusion: Why Try Anonymous Chat Platforms Like Omegle? Anonymous chat platforms offer an unfiltered way to connect with others without the usual social etiquettes or judgments. Omegle’s simplicity and the thrill of unpredictability make it a popular choice for those looking to chat with random strangers from all over the world. Whether you want to practice a language, swap stories, or just find someone to talk to on a slow afternoon, Omegle’s anonymous chat can be an interesting and sometimes surprising experience. By following basic safety guidelines and keeping an open mind, you can enjoy the randomness and diversity of conversations that these platforms provide. If you’re curious to try it yourself, you can start exploring the possibilities at Omegle and see who you meet next! Anonymous chatting is a portal into human stories, viewpoints, and sometimes just fun randomness — perfect for the curious, the social, or anyone in need of a break from the usual digital routine. Give it a try and see where your next conversation might take you!
