#термин Как меняется значение термина со временем...
Сейчас термином cross-validation (перекрёстная проверка / скользящий контроль) называют практически любой способ "честной оценки её качества" (см. wiki). Более 20 лет назад под этим понимали, в основном, тестирование с равномерными разбиениям выборки: - Leave-p-out cross-validation, - Leave-one-out cross-validation, - k-fold cross-validation. А вот когда мы выборку делим на две части, на одной обучаемся, на другой контролируемся, называлось отложенным контролем (Holdout method) - видите, тут даже в названии нет "cross-validation".
И вот что написано на Wiki: "many sources instead classify holdout as a type of simple validation, rather than a simple or degenerate form of cross-validation".
На русской Wiki, кстати, вообще радикально отождествляют cross-validation = k-fold cross-validation (что соответствует старой терминологии).

Since January 2022, the SC has received a total of 47 complaints and enquiries on illegal investment schemes promoted through Telegram. These fraudulent schemes offer non-existent investment opportunities, promising very attractive and risk-free returns within a short span of time. They commonly offer unrealistic returns of as high as 1,000% within 24 hours or even within a few hours. Artem Kliuchnikov and his family fled Ukraine just days before the Russian invasion. Pavel Durov, a billionaire who embraces an all-black wardrobe and is often compared to the character Neo from "the Matrix," funds Telegram through his personal wealth and debt financing. And despite being one of the world's most popular tech companies, Telegram reportedly has only about 30 employees who defer to Durov for most major decisions about the platform. "We're seeing really dramatic moves, and it's all really tied to Ukraine right now, and in a secondary way, in terms of interest rates," Octavio Marenzi, CEO of Opimas, told Yahoo Finance Live on Thursday. "This war in Ukraine is going to give the Fed the ammunition, the cover that it needs, to not raise interest rates too quickly. And I think Jay Powell is a very tepid sort of inflation fighter and he's not going to do as much as he needs to do to get that under control. And this seems like an excuse to kick the can further down the road still and not do too much too soon." Meanwhile, a completely redesigned attachment menu appears when sending multiple photos or vides. Users can tap "X selected" (X being the number of items) at the top of the panel to preview how the album will look in the chat when it's sent, as well as rearrange or remove selected media.
