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

Bézier Triangles with G2 Continuity across Boundaries

Autor: Chang-Ki Lee, Hae-Do Hwang, Seung-Hyun Yoon

Publikováno v: Symmetry, Vol 8, Iss 3, p 13 (2016)

PN (point-normal) triangles are cubic Bézier triangles which meet at their edges to surface a triangular mesh, but this only achieves G0 continuity. We define blending regions that span the edges shared by adjacent pairs of triangular domains and bl

Comparison of the Physical Care Burden on Formal Caregivers between Manual Human Care Using a Paper Diaper and Robot-Aided Care in Excretion Care

Autor: Jeong-Bae Ko, Yong-Ku Kong, Kyeong-Hee Choi, Chang-Ki Lee, Hyun-Ji Keum, Jae-Soo Hong, Byeong-Hee Won

Publikováno v: International Journal of Environmental Research and Public Health; Volume 20; Issue 2; Pages: 1281

Although the older population has been rapidly growing, the availability of formal caregivers remains limited. Assistance provided by care robots has helped lower this burden; however, whether using a care robot while providing excretion care (EC) is

Annals of Geriatric Medicine and Research

The Aging Study of Pyeongchang Rural Area (ASPRA) is a population-based, prospective cohort study of older adults in Pyeongchang, South Korea. Since the initial enrollment of 382 participants, the ASPRA has been maintained and has conducted comprehen
