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.

Sebi said data, emails and other documents are being retrieved from the seized devices and detailed investigation is in progress. The account, "War on Fakes," was created on February 24, the same day Russian President Vladimir Putin announced a "special military operation" and troops began invading Ukraine. The page is rife with disinformation, according to The Atlantic Council's Digital Forensic Research Lab, which studies digital extremism and published a report examining the channel. These entities are reportedly operating nine Telegram channels with more than five million subscribers to whom they were making recommendations on selected listed scrips. Such recommendations induced the investors to deal in the said scrips, thereby creating artificial volume and price rise. That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future. As a result, the pandemic saw many newcomers to Telegram, including prominent anti-vaccine activists who used the app's hands-off approach to share false information on shots, a study from the Institute for Strategic Dialogue shows.
