Summary: This paper proposes a novel support vector machine model with feature mapping and kernel trick to handle datasets with different distributions. The model improves robustness by pre-selecting training points, and converts the problem into a convex quadratic programming problem solved efficiently by the sequential minimal optimization algorithm. Numerical tests demonstrate the superior performance of the proposed method compared to other classification methods.

Summary: This article proposes and studies a new efficient tool called Local-to-Global Support Vector Machine (LGSVM) for supervised classification tasks that involve a large number of instances. It constructs a global classifier by gluing together the local SVM contributions via compactly supported weights, which significantly reduces the complexity cost of SVMs for large-scale datasets.

Summary: This paper proposes a Hessian scatter regularized twin support vector machine (HSR-TSVM) based on Laplacian regularization. HSR-TSVM can better maintain the local topology of the samples and improve classification performance by utilizing the structural information of samples. Furthermore, a least-squares version of HSR-TSVM called HSR-LSTSVM is proposed to improve computational efficiency.

Summary: In this paper, a hypergraph regularized semi-supervised support vector machine (HGSVM) algorithm is proposed to exploit the multivariate manifold structure. To accelerate the training process of HGSVM, a fast algorithm based boundary sample selection algorithm, termed fast-HGSVM, is developed. Moreover, two SMOTE-variant techniques and the one-vs-rest strategy are introduced in fast-HGSVM, and two multi-category semi-supervised algorithms called fast-ASHGSVM and fast-KSHGSVM are proposed. The effectiveness of the proposed algorithms is validated through experiments on two moons and UCI datasets.

Summary: This study proposes a new method called simplex-based proximal MSVM (SPMSVM) as a refinement of the regular multicategory support vector machine (MSVM). The SPMSVM uses a novel family of squared error loss functions and removes the sum-to-zero constraint, resulting in closed-form solutions and reduced computational cost. It can be cast into a weighted regression problem and provides direct probabilistic results, making it more informative and scalable for large-scale applications. Simulations and real examples demonstrate that the SPMSVM is a stable, scalable, and competitive classifier.

Summary: In this study, different kernel functions of support vector machine (SVM) were compared for landslide susceptibility prediction. The experimental results showed that Laplacian-SVM had the highest prediction performance, and SVMs with RBF kernel were more suitable for this problem compared to SVMs with linear kernel. Furthermore, SVM-based methods demonstrated a higher sensitivity in finding potential landslide areas compared to deep learning methods.

Summary: Applying machine learning tools to human activity analysis faces two major challenges: the transformation of actions into multiple attributes increases training and testing time significantly, and the presence of noises and outliers in the dataset adds complexity and makes it difficult to implement the activity detection system efficiently. This paper proposes a kernel fuzzy proximal support vector machine as a robust classifier to address these challenges. The proposed method transforms input patterns into a higher-dimensional space and assigns appropriate membership degrees to reduce the impact of noises and outliers, and it achieves computational efficiency by solving a set of linear equations. Simulation results on benchmark problems and numerical results on human activity recognition problems demonstrate the superiority and applicability of the proposed method.
