  "Description": "This is a modification of 'HDoutliers' package. The\n'HDoutliers' algorithm is a powerful unsupervised algorithm for\ndetecting anomalies in high-dimensional data, with a strong\ntheoretical foundation. However, it suffers from some\nlimitations that significantly hinder its performance level,\nunder certain circumstances. This package implements the\nalgorithm proposed in Talagala, Hyndman and Smith-Miles (2019)\n<arXiv:1908.04000> for detecting anomalies in high-dimensional\ndata that addresses these limitations of 'HDoutliers'\nalgorithm. We define an anomaly as an observation that deviates\nmarkedly from the majority with a large distance gap. An\napproach based on extreme value theory is used for the\nanomalous threshold calculation.",
