Topological regularization with information filtering networks

نویسندگان

چکیده

This paper introduces a novel methodology to perform topological regularization in multivariate probabilistic modeling by using sparse, complex, networks which represent the system’s dependency structure and are called information filtering (IFN). can be directly applied covariance selection problem providing an instrument for sparse with both linear non-linear probability distributions such as elliptical generalized hyperbolic families. It also implemented of multicollinear regression. In this paper, I describe detail application Student-t. A specific expectation–maximization likelihood maximization procedure over chordal network representation is proposed Student-t case. Examples real data from stock prices log-returns artificially generated demonstrate applicability, performances, robustness potentials methodology.

Collaborative Filtering with Entity Similarity Regularization in Heterogeneous Information Networks

Researchers have been studying hybrid recommender systems which combine user-item rating data with external information in recent years. Some studies suggest that by leveraging additional user and / or item relations, e.g., social network, the performance of the recommendation models can be improved. These studies, nevertheless, mostly utilize a single type of external relationship. Considering...

A Topological Criterion for Filtering Information in Complex Brain Networks

In many biological systems, the network of interactions between the elements can only be inferred from experimental measurements. In neuroscience, non-invasive imaging tools are extensively used to derive either structural or functional brain networks in-vivo. As a result of the inference process, we obtain a matrix of values corresponding to a fully connected and weighted network. To turn this...

Parsimonious modeling with Information Filtering Networks

We introduce a methodology to construct parsimonious probabilistic models. This method makes use of information filtering networks to produce a robust estimate of the global sparse inverse covariance from a simple sum of local inverse covariances computed on small subparts of the network. Being based on local and low-dimensional inversions, this method is computationally very efficient and stat...

Heterogeneous Information Networks Bi-clustering with Similarity Regularization

Clustering analysis of multi-typed objects in heterogeneous information network (HINs) is an important and challenging problem. Nonnegative Matrix Tri-Factorization (NMTF) is a popular bi-clustering algorithm on document data and relational data. However, few algorithms utilize this method for clustering in HINs. In this paper, we propose a novel bi-clustering algorithm, BMFClus, for HIN based ...

Learning with Regularization Networks

In this work we study and develop learning algorithms for networks based on regularization theory. In particular, we focus on learning possibilities for a family of regularization networks and radial basis function networks (RBF networks). The framework above the basic algorithm derived from theory is designed. It includes an estimation of a regularization parameter and a kernel function by min...
