Stochastic differential equations driven by fractional Brownian motion with locally Lipschitiz drift and their Euler approximation
Shao-Qin Zhang, Chenggui Yuan
In this paper, we study a class of one-dimensional stochastic differential equations driven by fractional Brownian motion with Hurst parameter $H>\ff 1 2$. The drift term of the eq…
Exponential convergence in Wasserstein Distance for Diffusion Semigroups with Irregular Drifts
Shao-Qin Zhang
The exponential contraction in -Wasserstein distance and exponential convergence in -Wasserstein distance () are considered for stochastic differential equations…
Identifying multi-scale communities in networks by asymptotic surprise
Ju Xiang, Yan Zhang, Jian-Ming Li +2
Optimizing statistical measures for community structure is one of the most popular strategies for community detection, but many of them lack the flexibility of resolution and thus…
Zero-entropy dynamical systems with the gluing orbit property
Peng Sun
Under the assumption of the gluing orbit property, equivalent conditions to having zero topological entropy are investigated. In particular, we show that a dynamical system has the…
On the Entropy of Flows with Reparametrized Gluing Orbit Property
Peng Sun
We show that a flow or a semiflow with a weaker reparametrized form of gluing orbit property is either minimal or of positive topological entropy.
Deep Co-investment Network Learning for Financial Assets
Yue Wang, Chenwei Zhang, Shen Wang +3
Most recent works model the market structure of the stock market as a correlation network of the stocks. They apply pre-defined patterns to extract correlation information from the…
Identifying The Most Informative Features Using A Structurally Interacting Elastic Net
Lixin Cui, Lu Bai, Zhihong Zhang +2
Feature selection can efficiently identify the most informative features with respect to the target feature used in training. However, state-of-the-art vector-based methods are una…
Graph Convolutional Neural Networks based on Quantum Vertex Saliency
Lu Bai, Yuhang Jiao, Luca Rossi +3
This paper proposes a new Quantum Spatial Graph Convolutional Neural Network (QSGCNN) model that can directly learn a classification function for graphs of arbitrary sizes. Unlike…
Minimality and Gluing Orbit Property
Peng Sun
We show that a topological dynamical system is either minimal or have positive topological entropy. Moreover, for equicontinuous systems, we show that topological transitivity, min…
-openness of non-uniform hyperbolic diffeomorphisms with bounded norm
Chao Liang, Karina Marin, Jiagang Yang
We study the -topological properties of the subset of non-uniform hyperbolic diffeomorphisms in a certain class of partially hyperbolic symplectic systems which have bou…
Joint Nonnegative Matrix Factorization for Community Structures Detection in Signed Networks
Chao Yan, Hui-Min Cheng, Xin Liu +1
Community structures detection in signed network is very important for understanding not only the topology structures of signed networks, but also the functions of them, such as in…
On the vertex cover number of 3 uniform hypergraph
Zhuo Diao
Given a hypergraph H(V;E), a set of vertices S in V is a vertex cover if every edge has at least a vertex in S. The vertex cover number is the minimum cardinality of a vertex cover…
Evaluation of Community Detection Methods
Xin Liu, Hui-Min Cheng, Zhong-Yuan Zhang
Community structures are critical towards understanding not only the network topology but also how the network functions. However, how to evaluate the quality of detected community…
On invariant probability measures of regime-switching diffusion processes with singular drifts
Shao-Qin Zhang
For regime-switching diffusions processes with singular drifts, we introduce integrability conditions involving a nice reference probability measure and the -matrix of the jump…
