Outlier detection is an important issue in data mining and knowledge discovery. The aim is to find the patterns that deviate too much from others. In this paper, a universal outlier detection method based on normalized residual is proposed. Different from previous methods, the residual of a pattern is calculated corresponding to its nearest normal patterns, so that the interaction between outliers...
Software systems are important components for the deployment and operation of large-scale critical systems, such as nuclear plants and aerospace shuttles. The very high reliability is critically required. Due to the very large scale and computational complexity, however, there are some inherent challenges for conducting extensive testing. In this paper, we define such challenges in the testing scope...
Water transmission and distribution systems are critical urban infrastructure. The aging of water mains can lead to increased breakage rate, decreased hydraulic capacity, and deterioration of water quality. Condition assessment of water mains encompasses building computational model of failures, discerning distress indicators from inspection, rating health condition, and forecasting future failures...
In this short paper, we figure out the challenges for efficiently detecting bugs in large-scale nuclear power software. Then, an automated test platform with random testing mechanism is proposed to achieve good outcomes.
Performance of analog integrated circuits is highly sensitive to layout parasitics. This paper presents an improved template-based algorithm that automatically conducts performance-constrained parasitic-aware retargeting and optimization of analog layouts. In order to achieve desired circuit performance, performance sensitivities with respect to layout parasitics are first determined. Then the algorithm...
Performance of analog circuits is highly sensitive to layout parasitics. This paper presents an improved algorithm that automatically conducts performance-constrained parasitic-aware retargeting and optimization of analog layouts. In order to meet the desired circuit specification, performance sensitivities with respect to layout parasitics are first determined. Then the algorithm applies sensitivity-based...
