Community Detection of Multi-Layer Attributed Networks via Penalized Alternating Factorization
Communities are often associated with important structural characteristics of a complex network system, therefore detecting communities is considered to be a fundamental problem in network analysis.

Evolutionary Based ICA With Reference for EEG
Independent component analysis with reference (ICA-R), a paradigm of constrained ICA (cICA), incorporates textita priori information about the desired sources as reference signals into the contrast function of ICA.

Sparse Graph Learning Under Laplacian-Related Constraints
We consider the problem of learning a sparse undirected graph underlying a given set of multivariate data. We focus on graph Laplacian-related constraints on the sparse precision matrix that encodes conditional dependence between the random variables ...

Fuzzy Real-Time Optimization of the Tennessee Eastman Challenge Process [PDF]
A Real-Time Optimization (RTO) strategy incorporating the fuzzy sets theory is developed, where the problem constraints obtained from process considerations are treated in fuzzy environment. Furthermore, the objective function is penalized by a fuzzified

The kriging-based estimation of the different types of atmospheric particulate matter (PM) pollutions defined in the air quality regulation raises some operational problems because the (co)kriging equations are obtained by minimizing a linear combination

Alternating direction method of multipliers for penalized zero-variance discriminant analysis [PDF]
We consider the task of classification in the high dimensional setting where the number of features of the given data is significantly greater than the number of observations.

Sharp interface limit for a phase field model in structural optimization
We formulate a general shape and topology optimization problem in structural optimization by using a phase field approach. This problem is considered in view of well-posedness and we derive optimality conditions.
