Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Estimating Time-Varying Networks for High-Dimensional Time Series
高维 时间序列 时变网络

2023/4/25
We explore time-varying networks for high-dimensional locally stationary time series, using the large VAR model framework with both the transition and (error) precision matrices evolving smoothly over...

The program aims at showing the role of modern statistical methods in complex data and serves to support interactions among mathematicians, statisticians, engineers and scientists working in the inter...
Scoring Bayesian Networks with Informative, Causal and Associative Priors
Scoring Bayesian Networks Informative Causal Associative Priors

A significant theoretical advantage of search-and-score methods for learning Bayesian Networks is that they can accept informative prior beliefs for each possible network, thus complementing the data....

2012/11/23
This work considers the problem of learning linear Bayesian networks when some of the variables are unobserved. Identifiability and efficient recovery from low-order observable moments are established...
Two-Photon Exchange Effect Studied with Neural Networks
Two-Photon Exchange Neural Networks

2011/7/21
The novel approach to the extraction of the two-photon exchange (TPE) correction from the elastic $ep$ scattering data is presented. The Bayesian framework for the neural networks is adapted. As the r...

We propose an efficient scheme for generating fake network traffic to disguise the real event notification in the presence of a global eavesdropper, which is especially relevant for the quality of ser...
Collective chaos in pulse-coupled neural networks
Disordered Systems and Neural Networks (cond-mat.dis-nn) Chaotic Dynamics (nlin.CD)
font style='font-size:12px;'>
2010/11/10
We study the dynamics of two symmetrically coupled populations of leaky integrate-and-fire neurons characterized by an excitatory coupling. Upon varying the coupling strength, we find symmetry-breakin...
Stratified economic exchange on networks
Physics and Society (physics.soc-ph) Social and Information Networks (cs.SI) Cellular Automata and Lattice Gases (nlin.CG)
font style='font-size:12px;'>
2010/11/10
We investigate a model of stratified economic interactions between agents when the notion of spatial location is introduced. The agents are placed on a network with near-neighbor connections. Interact...
Sandpile cascades on interacting tree-like networks
Disordered Systems and Neural Networks (cond-mat.dis-nn) Adaptation and Self-Organizing Systems (nlin.AO)
font style='font-size:12px;'>
2010/11/10
The vulnerability of an isolated network to cascades is fundamentally affected by its interactions with other networks. Motivated by failures cascading among electrical grids, we study the Bak-Tang-Wi...
Complexity, information transfer and collective behavior in chaotic dynamical networks
Chaotic Dynamics (nlin.CD) Adaptation and Self-Organizing Systems (nlin.AO)
font style='font-size:12px;'>
2010/11/10
We investigate the relationship between complexity, information transfer and the emergence of collective behaviors, such as synchronization and nontrivial collective behavior, in a network of globally...
