❓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.

Since January 2022, the SC has received a total of 47 complaints and enquiries on illegal investment schemes promoted through Telegram.
