چکیده
Abstract Performing multiple experiments is common when learning internal mechanisms of complex systems. These can include perturbations parameters or external disturbances. A challenging problem to efficiently incorporate all collected data simultaneously infer the underlying dynamic network. This paper addresses reconstruction networks from heterogeneous datasets under assumption that share same Boolean structure across experiments. Parametric models are derived for dynamical functions, which describe causal interactions between measured variables. Multiple integrated into one regression with additional demands on group sparsity assure network and consistency. To acquire structured sparsity, we propose a sampling-based method, together extended versions l 1 -methods sparse Bayesian learning. The performance proposed methods benchmarked in numerical simulation. In summary, this presents efficient experiments, reveals practical experience could guide applications.

Linear Dynamic Network Reconstruction from Heterogeneous Datasets
This paper addresses reconstruction of linear dynamic networks from heterogeneous datasets. Those datasets consist of measurements from linear dynamical systems in multiple experiment subjected to different experimental conditions, e.g., changes/perturbations in parameters, disturbance or noise. A main assumption is that the Boolean structures of the underlying networks are the same in all expe...
متن کاملReconstruction of Network Coded Sources From Incomplete Datasets
We investigate the problem of recovering source information from an incomplete set of network coded data with help of prior information about the sources. This problem naturally arises in wireless networks, where the number of network coded packets available at the receiver may not be sufficient for exact decoding due to channel dynamics or timing constraints, for example. We study the theoreti...
متن کاملExploring Heterogeneous Datasets from Different Searcher Perspectives
This paper demonstrates how a recently developed analytical usability evaluation method, the Sii framework, can by used to inspect semantic search interfaces for how they support people working with the large heterogeneous datasets afforded by Linked Data. To enrich the discussion, an analysis of the Tabulator browser for Linked Data is presented and discussed in terms of the workshop’s case st...
متن کاملClassification of Resting State fMRI Datasets Using Dynamic Network Clusters
Resting state functional magnetic resonance imaging (rsfMRI) is a powerful tool for investigating intrinsic and spontaneous brain activity. The application of univariate and multivariate methods such as multi voxel pattern analysis has been instrumental in localizing neural correlates to various cognitive states and psychiatric disease. However, many existing methods of rsfMRI analysis are insu...
