عنوان مقاله فارسی: آزمون‌های تشخیص تغییر سلسله مراتبی عنوان مقاله لاتین: Hierarchical Change-Detection Tests نویسندگان: Cesare Alippi; Giacomo Boracchi; Manuel Roveri تعداد صفحات: 12 سال انتشار: 2017 زبان: لاتین Abstract: We present hierarchical change-detection tests (HCDTs), as effective online algorithms for detecting changes in datastreams. HCDTs are characterized by a hierarchical architecture composed of a detection layer and a validation layer. The detection layer steadily analyzes the input datastream by means of an online, sequential CDT, which operates as a low-complexity trigger that promptly detects possible changes in the process generating the data. The validation layer is activated when the detection one reveals a change, and performs an offline, more sophisticated analysis on recently acquired data to
