#книга Simovici D. A. CLUSTERING: Theoretical and Practical Aspects. – World Scientific, 2021. Неплохая книга по кластеризации - для любителей жёсткой теории, сначала даётся большой математический обзор: ЧУМ, энтропия, выпуклые множества, гиперграфы, мультимножества (выше был пост про обобщённую энтропию - там рисунки из этой книги), потом уже разбираются алгоритмы кластеризации. Много теорем с доказательствами. Примеры кода на python и R (тут на чём удобнее, на том автор и писал). В приложении опять много математики: спектральные функции, проблема NP-полноты и т.п. Из минусов: нет как примеров практических кейсов кластеризации, так и каких-то советов для практиков.

There was another possible development: Reuters also reported that Ukraine said that Belarus could soon join the invasion of Ukraine. However, the AFP, citing a Pentagon official, said the U.S. hasn’t yet seen evidence that Belarusian troops are in Ukraine. You may recall that, back when Facebook started changing WhatsApp’s terms of service, a number of news outlets reported on, and even recommended, switching to Telegram. Pavel Durov even said that users should delete WhatsApp “unless you are cool with all of your photos and messages becoming public one day.” But Telegram can’t be described as a more-secure version of WhatsApp. 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. 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. During the operations, Sebi officials seized various records and documents, including 34 mobile phones, six laptops, four desktops, four tablets, two hard drive disks and one pen drive from the custody of these persons.
