Papers

Thesis

  1. Anomaly Detection based on Compression Data using Clustering Algorithm

    Jong-Ha Ahn. M.S. Thesis, Depart. of Computer Science, The Graduate School of Information, Chung-Ang Univ., 2011.

Korean Articles

  1. K-means 클러스터링을 이용한 압축 기반 이상탐지

    정보과학회 논문지: 소프트웨어 및 응용 39(8):605-612, 2012년 8월;안종하, 김대원.

    This study presents a new method for storing large log data, and simultaneously, detecting anomaly data. To achieve this, the well-known K-means clustering algorithm is used for the anomaly detection. In K-means algorithm, the dissimilarity between data is calculated on the space transformed by the Logpack compression algorithm. We also performed a feature selection using genetic algorithms to obtain an informative subset of features relevant to anomaly events. Through various tests, it is observed that the proposed method is superior to conventional algorithms.
