Статья с новым подходом для тренировки эмбеддингов - использование контекста для получения эмбеддингов документов. Предлагают два улучшения: contrastive learning включающий соседние документы в лосс внутри батча; новая архитектура, которая явно использует информацию соседних документов. Эти подходы улучшают результаты по сравнению с другими biencoders, особенно в условиях out-of-domain. Авторы получают SOTAна бенчмарке MTEB без использования трюков типа hard negative mining или больших батчи. Плюс предложенные улучшения можно применять к другим подходам contrastive learning.

Overall, extreme levels of fear in the market seems to have morphed into something more resembling concern. For example, the Cboe Volatility Index fell from its 2022 peak of 36, which it hit Monday, to around 30 on Friday, a sign of easing tensions. Meanwhile, while the price of WTI crude oil slipped from Sunday’s multiyear high $130 of barrel to $109 a pop. Markets have been expecting heavy restrictions on Russian oil, some of which the U.S. has already imposed, and that would reduce the global supply and bring about even more burdensome inflation. Since its launch in 2013, Telegram has grown from a simple messaging app to a broadcast network. Its user base isn’t as vast as WhatsApp’s, and its broadcast platform is a fraction the size of Twitter, but it’s nonetheless showing its use. While Telegram has been embroiled in controversy for much of its life, it has become a vital source of communication during the invasion of Ukraine. But, if all of this is new to you, let us explain, dear friends, what on Earth a Telegram is meant to be, and why you should, or should not, need to care. The original Telegram channel has expanded into a web of accounts for different locations, including specific pages made for individual Russian cities. There's also an English-language website, which states it is owned by the people who run the Telegram channels. Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts. Either way, Durov says that he withdrew his resignation but that he was ousted from his company anyway. Subsequently, control of the company was reportedly handed to oligarchs Alisher Usmanov and Igor Sechin, both allegedly close associates of Russian leader Vladimir Putin.
