Apache Spark enables fast computations and greatly accelerates analytics applications by efficiently utilizing the main memory caching data for later use. At its core uses structures called RDDs (Resilient Distributed Datasets) to give a unified view distributed data. However, represented in remain unencrypted which can result leakage of confidential produced or processed applications. persists (unencrypted) disk storage under various circumstances including but not limited caching, RDD...
Change detection in system behavior and its root cause is essential for many large-scale systems such as, manufacturing plants, order to keep running uninterrupted avoid costly machine breakdown via predictive maintenance. In this paper, we present a novel graph based technique that uses time variant interdependencies lagged dependencies among different components of detect changes the behavior. We further find causes these detected by pointing out component historical values are responsible...
Discovering temporal lagged and inter-dependencies in multivariate time series data is an important task. However, many real-world applications with big data, such as commercial cloud management or predictive maintenance manufacturing, dependencies can be time-variant non-linear, which makes it more challenging to extract through traditional methods like Granger causality statistical models. In this work, we present a novel deep learning model that uses multiple layers of adapted gated...
Sensor applications are typically composed of a number functional components that run distributedly on the nodes sensor network, communicating and interacting with one another. Service composition is emerging as viable approach towards automatic synthesis such applications. However, for service to be practical, it has comply policies define security management constraints use these interconnections amongst them. Prior research efforts have primarily focused efficient evaluation during...
