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.

READ MORE These administrators had built substantial positions in these scrips prior to the circulation of recommendations and offloaded their positions subsequent to rise in price of these scrips, making significant profits at the expense of unsuspecting investors, Sebi noted. In February 2014, the Ukrainian people ousted pro-Russian president Viktor Yanukovych, prompting Russia to invade and annex the Crimean peninsula. By the start of April, Pavel Durov had given his notice, with TechCrunch saying at the time that the CEO had resisted pressure to suppress pages criticizing the Russian government. "There are a lot of things that Telegram could have been doing this whole time. And they know exactly what they are and they've chosen not to do them. That's why I don't trust them," she said. The company maintains that it cannot act against individual or group chats, which are “private amongst their participants,” but it will respond to requests in relation to sticker sets, channels and bots which are publicly available. During the invasion of Ukraine, Pavel Durov has wrestled with this issue a lot more prominently than he has before. Channels like Donbass Insider and Bellum Acta, as reported by Foreign Policy, started pumping out pro-Russian propaganda as the invasion began. So much so that the Ukrainian National Security and Defense Council issued a statement labeling which accounts are Russian-backed. Ukrainian officials, in potential violation of the Geneva Convention, have shared imagery of dead and captured Russian soldiers on the platform.
