A novel algorithm for multiplicative speckle noise reduction in ex vivo human brain OCT images
Optical coherence tomography (OCT) images of ex vivo human brain tissue are corrupted by multiplicative speckle noise that degrades the contrast to noise ratio (CNR) of microstructural compartments.

Robust 3D point cloud registration based on bidirectional Maximum Correntropy Criterion. [PDF]
This paper presents a robust 3D point cloud registration algorithm based on bidirectional Maximum Correntropy Criterion (MCC). Comparing with traditional registration algorithm based on the mean square error (MSE), using the MCC is superior in dealing ...

Sparse Multicategory Generalized Distance Weighted Discrimination in Ultra-High Dimensions
Distance weighted discrimination (DWD) is an appealing classification method that is capable of overcoming data piling problems in high-dimensional settings. Especially when various sparsity structures are assumed in these settings, variable selection in

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

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 ...
