Abstract: Methods and systems for detecting anomalous communications include simulating a network graph based on community and role labels of each node in the network graph based on one or more linking rules. The community and role labels of each node are adjusted based on differences between the simulated network graph and a true network graph. The simulation and adjustment are repeated until the simulated network graph converges to the true network graph to determine a final set of community and role labels. It is determined whether a network communication is anomalous based on the final set of community and role labels.

Abstract: Systems and methods for managing components of physical systems, including decomposing raw time series by extracting an aging trend and a fluctuation term from the time series using an objective function of an optimization problem, the objective function minimizing reconstruction error and ensuring flatness of the fluctuation term over time. The optimization problem is transformed into a Quadratic Programming (QP) formulation including a monotonicity constraint and a non-negativity constraint, the constraints being merged together to reduce computational costs. An aging score and a confidence score are generated for the extracted aging trend to determine a severeness of aging for one or more components of the physical system, and the aging score and confidence score are fused to provide a fused ranking for the extracted aging trend for predicting future failures of the components.

Abstract: A method and system are provided. The method includes determining from a data matrix having rows and columns, a clustering vector of the rows and a clustering vector of the columns. Each row in the clustering vector of the rows is a row instance and each row in the clustering vector of the columns is a column instance. The method further includes performing correlation of the row and column instances. The method also includes building a normalizing graph using a graph-based manifold regularization that enforces a smooth target function which, in turn, assigns a value on each node of the normalizing graph to obtain a Lapacian matrix. The method additionally includes performing Eigenvalue decomposition on the Lapacian matrix to obtain Eigenvectors. The method further includes providing a canonical co-clustering analysis function by maximizing a coupling between clustering vectors while concurrently enforcing regularization on each clustering vector using the Eigenvectors.
