TL;DR提出两种新的 AD 算法,以解决 Functional Isolation Forest (FIF) 在线性内积和词典选择方面的限制,结果通过多个数值实验得到验证。
Abstract
functional isolation forest (FIF) is a recent state-of-the-art Anomaly
Detection (AD) algorithm designed for functional data. It relies on a tree
partition procedure where an abnormality score is computed by proj
