Special Issue Information

Dear Colleagues,

Big data have become fundamental in various science, technology, and engineering fields. As our ability to store vast datasets grows, so does the need to develop advanced computational algorithms for analyzing and extracting meaningful information. This necessitates the creation of effective and functional machine learning methods and the computational and numerical approaches to implement them efficiently.

Artificial intelligence applications are vast and far-reaching, impacting and revolutionizing fields like healthcare, engineering, fraud detection, climate science, information science, and more fundamental sciences like physics and chemistry. As such, algorithm development and advances in computational performance are fundamental topics in today's research at the crossroads of applied mathematics, statistics, and computer science.

This Special Issue aims to foster discussions and insights in this multidisciplinary field.

Non-sparse multiple kernel learning is efficient but not directly able to be applied in a semi-supervised scenario; therefore, we extend it to semi-supervised learning by using a manifold regularization. The manifold regularization is based on a graph constructed on all the data samples including the labeled and the unlabeled, and forces the regularized classifier smooth along the graph. In this study, we propose the manifold regularized p-norm multiple kernels model and provide the solutions with proofs. The risk bound is briefly introduced based on the local Rademacher complexity. Experiments on several datasets and comparisons with several methods show that the efficiency of the proposed model to be used in semi-supervised scenario. Full article

This study tackles the challenge of splitting and merging in parametric active contours or snakes. The proposed method comprises three stages: (1) fully 4-connected interpolation, (2) snake splitting, and (3) snakes merging. For this purpose, first, the coordinates of snake points are separated into two corrupted 1D signals, with missing X/Y samples in the signals representing missing snakes’ coordinates. These missing X/Y samples are estimated using a constrained Tikhonov regularisation model, ensuring fully 4-connected snakes. Next, crossing points are identified by plotting snake points onto a raster matrix, detecting overlaps where multiple snake points occupy the same raster cell. Finally, snakes are split or merged by extracting snake points between crossing snake points that form a loop using a heuristic approach. Experimental results on the boundary detection of enamel in Micro-CT images and coronary arteries’ lumen in CT images demonstrate the proposed method’s ability to handle contour splitting and merging effectively.
