❓الگوریتم جنگل ایزوله (Isolation Forest) یا جنگل جداسازی
یک الگوریتم «یادگیری بدون نظارت» (Unsupervised Learning Algorithm) برای تشخیص ناهنجاری (Anomaly) است که برای جداسازی نقاط پرت (Outlier) به کار می‌رود.
البته در اغلب روش‌های شناسایی نقاط پرت، بقیه نقاط که رفتار عادی دارند مورد ارزیابی قرار گرفته و براساس رفتار آن‌ها، نقاط پرت مشخص می‌شوند در حالیکه در الگوریتم جنگل ایزوله از ابتدا این گونه نقاط مورد بررسی قرار می‌گیرند.

The Securities and Exchange Board of India (Sebi) had carried out a similar exercise in 2017 in a matter related to circulation of messages through WhatsApp. But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website. On February 27th, Durov posted that Channels were becoming a source of unverified information and that the company lacks the ability to check on their veracity. He urged users to be mistrustful of the things shared on Channels, and initially threatened to block the feature in the countries involved for the length of the war, saying that he didn’t want Telegram to be used to aggravate conflict or incite ethnic hatred. He did, however, walk back this plan when it became clear that they had also become a vital communications tool for Ukrainian officials and citizens to help coordinate their resistance and evacuations. Pavel Durov, Telegram's CEO, is known as "the Russian Mark Zuckerberg," for co-founding VKontakte, which is Russian for "in touch," a Facebook imitator that became the country's most popular social networking site. Following this, Sebi, in an order passed in January 2022, established that the administrators of a Telegram channel having a large subscriber base enticed the subscribers to act upon recommendations that were circulated by those administrators on the channel, leading to significant price and volume impact in various scrips.
