#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).

Emerson Brooking, a disinformation expert at the Atlantic Council's Digital Forensic Research Lab, said: "Back in the Wild West period of content moderation, like 2014 or 2015, maybe they could have gotten away with it, but it stands in marked contrast with how other companies run themselves today." The regulator said it has been undertaking several campaigns to educate the investors to be vigilant while taking investment decisions based on stock tips. Just days after Russia invaded Ukraine, Durov wrote that Telegram was "increasingly becoming a source of unverified information," and he worried about the app being used to "incite ethnic hatred." Telegram has become more interventionist over time, and has steadily increased its efforts to shut down these accounts. But this has also meant that the company has also engaged with lawmakers more generally, although it maintains that it doesn’t do so willingly. For instance, in September 2021, Telegram reportedly blocked a chat bot in support of (Putin critic) Alexei Navalny during Russia’s most recent parliamentary elections. Pavel Durov was quoted at the time saying that the company was obliged to follow a “legitimate” law of the land. He added that as Apple and Google both follow the law, to violate it would give both platforms a reason to boot the messenger from its stores. At the start of 2018, the company attempted to launch an Initial Coin Offering (ICO) which would enable it to enable payments (and earn the cash that comes from doing so). The initial signals were promising, especially given Telegram’s user base is already fairly crypto-savvy. It raised an initial tranche of cash – worth more than a billion dollars – to help develop the coin before opening sales to the public. Unfortunately, third-party sales of coins bought in those initial fundraising rounds raised the ire of the SEC, which brought the hammer down on the whole operation. In 2020, officials ordered Telegram to pay a fine of $18.5 million and hand back much of the cash that it had raised.
