when fold is not an integer, how does refit work?

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/

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!

How to Experience Cookie Clicker: A Fun Dive into Store Management Gaming
by aesthetic.walrus.fioc＠rapidletter.net Sept. 6, 2025

Sept. 6, 2025

If you’ve ever dreamt of running your own bakery, or perhaps wanted to rule a cookie empire, then you'll love the world of store management games. One delightful example of this genre is Cookie Clicker. This incremental game combines simplicity with addictive gameplay, making it a perfect choice for new and seasoned gamers alike. In this article, we’ll explore how to play Cookie Clicker, provide tips to enhance your baking experience, and ensure you enjoy every aspect of your cookie quest. https://cookieclickerfree.io Gameplay: What is Cookie Clicker? At its core, Cookie Clicker is a game about baking cookies—lots of cookies! When you start, you are presented with a cookie button that you can click to produce cookies. Each click generates one cookie, and as your cookie count grows, so does your ability to invest in upgrades and generate cookies more efficiently. The Basics Click the Cookie: The first step in Cookie Clicker is to simply click on the giant cookie in the center of the screen. Each click earns you one cookie, and this basic action sets the stage for your cookie empire. Upgrades and Purchases: With the cookies you earn, you can buy various items from the store, such as cursors, grandmas, farms, and factories. Each of these items produces cookies automatically over time, allowing you to accumulate wealth without the need for constant clicking. The Cookie Economy: As with any store management game, understanding the economy is vital. Each item has a cost and a cookie production value. Balancing your investments is crucial for maximizing your cookie output. For instance, it might be wise to save up for a more expensive item that produces cookies at a higher rate, rather than buying multiple cheaper items. Achievements and Upgrades: As you play, you’ll unlock various achievements that reward you with bonuses. These can significantly boost your cookie production. Keep an eye out for these as they can greatly enhance your gameplay. Prestige Levels: Once you've mastered the basics and reached a substantial cookie count, you might consider resetting your progress to gain “Heavenly Chips.” This feature allows you to unlock powerful upgrades that will help you in your next round of cookie baking. It adds an extra layer of strategy to the game, as you’ll need to decide the best time to reset. Tips for Playing Cookie Clicker While Cookie Clicker is easy to pick up and play, there are some strategies that can make your experience much more enjoyable: Timing Your Clicks: While it’s tempting to keep clicking for cookies, you might find that setting a rhythm or using an auto-clicker (if you're comfortable with game modification) can help maximize your output. However, the joy of clicking is part of the game’s charm! Prioritize Upgrades: Focus on purchasing upgrades that provide the best return on investment. Early on, it might be worth investing in cursors and grandmas, but as you progress, you should shift your focus toward factories and banks, which provide more cookies more efficiently. Plan Your Strategy: Think ahead about which upgrades to purchase next. For example, buying a lot of lower-tier items might seem beneficial at first but can hinder your progress in the long run. Instead, save up for high-value items. Watch for Seasonal Events: Cookie Clicker often has seasonal events that provide bonuses and limited-time upgrades. Participating in these can give you an edge and add an element of fun and surprise to your gameplay. Take Breaks: It’s easy to get wrapped up in the cookie-making frenzy. Don’t forget to take breaks! Even with closed tabs, your cookie production continues, allowing you to return to a more substantial cookie stash. Conclusion: Enjoying Your Cookie Journey Cookie Clicker is a world where patience, strategy, and an insatiable love for cookies combine wonderfully. It's an amusing journey through the whimsical realm of bakery management, ensuring that players are constantly engaged with its lighthearted yet addictive gameplay. The progress you make from a humble clicker to a cookie magnate represents a satisfying achievement that keeps you coming back for more. As you embark on your cookie adventure, remember to have fun and enjoy the journey. Don’t stress too much about cookie counts or achieving perfection; the game is designed for enjoyment, with each click leading you closer to your cookie goals. So, why not start your journey now? Dive into the ever-expanding world of cookies at Cookie Clicker and let the delicious adventure begin! Happy baking!
