Least Squares Generative Adversarial Networks-Based Anomaly Detection
Autor: Chang-Ki Lee, Yu-Jeong Cheon, Wook-Yeon Hwang
Publikováno v: IEEE Access, Vol 10, Pp 26920-26930 (2022)
Multivariate statistical process control (MSPC) is a technique for detecting anomalies by monitoring several quality characteristics simultaneously. For the MSPC problem, the Hotelling’s $T^{2}$ control chart has been widely used as a typical metho

Studies on the GAN-Based Anomaly Detection Methods for the Time Series Data
Autor: Chang-Ki Lee, Yu-Jeong Cheon, Wook-Yeon Hwang
Publikováno v: IEEE Access, Vol 9, Pp 73201-73215 (2021)
Anomaly detection (AD) for times series data using the generative adversarial network (GAN) has been proposed in recent years. According to the previous study, the GAN-based AD outperformed the cumulative sum (CUSUM) chart. However, no framework for

Further Improvement on Two-Way Cooperative Collaborative Filtering Approaches for the Binary Market Basket Data
Autor: Wook-Yeon Hwang, Jong-Seok Lee
Publikováno v: Applied Sciences, Vol 11, Iss 19, p 8977 (2021)
Two-way cooperative collaborative filtering (CF) has been known to be crucial for binary market basket data. We propose an improved two-way logistic regression approach, a Pearson correlation-based score, a random forests (RF) R-square-based score, a

Quantile-based control charts for poisson and gamma distributed data
Autor: Wook-Yeon Hwang
Publikováno v: Journal of the Korean Statistical Society. 50:1129-1146
In terms of statistical process control (SPC), the probability distributions of the quality characteristics are critical in detecting changes in the process and product quality in manufacturing processes. Non-normally distributed output variables exp

Assessing new correlation-based collaborative filtering approaches for binary market basket data
Autor: Wook-Yeon Hwang
Publikováno v: Electronic Commerce Research and Applications. 29:12-18
Binary market basket data are common in marketing settings. Pearson correlation-based approaches have applied to this kind of data in the past. This research assessed the principles of this approach research identifies some related problems. By resol
