#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.

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. At this point, however, Durov had already been working on Telegram with his brother, and further planned a mobile-first social network with an explicit focus on anti-censorship. Later in April, he told TechCrunch that he had left Russia and had “no plans to go back,” saying that the nation was currently “incompatible with internet business at the moment.” He added later that he was looking for a country that matched his libertarian ideals to base his next startup. 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. Soloviev also promoted the channel in a post he shared on his own Telegram, which has 580,000 followers. The post recommended his viewers subscribe to "War on Fakes" in a time of fake news. In a statement, the regulator said the search and seizure operation was carried out against seven individuals and one corporate entity at multiple locations in Ahmedabad and Bhavnagar in Gujarat, Neemuch in Madhya Pradesh, Delhi, and Mumbai.
