Summary: The effectiveness of subsampling methods in reducing the required instances in the training stage of using support vector machines (SVMs) for classification in big data scenarios is explored in this paper with theoretical results. The main theorem states that, under certain conditions, a feasible solution can be found for the SVM problem using a randomly chosen subsample, which can be as close as desired to the classifier trained with the complete dataset in terms of classification error. Additionally, a new subsampling method called importance sampling and bagging is proposed, which provides a faster solution to the SVM problem without significant loss in accuracy compared to existing techniques.

Summary: This work demonstrates how to approximate the failure probability of an expensive computational model with reliability requirements using Support Vector Machines. An algorithm is proposed to select informative parameter points to improve the approximation accuracy iteratively. Additionally, a method is provided to quantify the uncertainty in the Limit State Function and estimate an upper bound to the failure probability using geometrical arguments.

Summary: This paper investigates the general forms and characteristics of nonparallel support vector machines (NSVMs) and categorizes them into two types. It reveals the advantages and defects of different types and points out the inconsistency problems. Based on this observation, a novel max-min distance-based NSVM is proposed with desired consistency. The proposed NSVM has the consistency of training and test and the consistency of metric, and it assigns each sample an ascertained loss.

Summary: This paper introduces a novel method called sparse support vector machine guided by radius-margin bound (RMB-SSVM) to efficiently condense the basis vectors in support vector machines. By selecting basis vectors and learning corresponding coefficients with a criterion related to SVM's generalization ability, the RMB-SSVM model can yield better performance.

Summary: The predictive performance of classification methods relies heavily on the nature of the environment and dataset shift issue. A novel Fuzzy Support Vector Machine strategy is proposed in this paper to improve performance by redefining the loss function and applying aggregation operators to deal with dataset shift. Our methods outperform traditional classifiers in terms of out-of-time prediction using simulated and real-world dataset for credit scoring.

Summary: In this study, a three-stage adaptive support vector regression (SVR) model is built to alleviate the scarcity of samples in the reliability evaluation of structures with implicit limit state functions (LSFs). The model employs sequential and importance sampling techniques to ensure a sufficient number of simulation points near the failure plane for accurate estimation of reliability.

Summary: In this study, improved regression and classification rates for support vector machines are derived based on the assumption of low-dimensional intrinsic structure described by the box-counting dimension. Learning rates are proved under standard regularity assumptions, where the ambient space dimension is replaced by the box-counting dimension of the data generating distribution support. Furthermore, a training validation approach for choosing SVM hyperparameters in a data-dependent manner is shown to achieve the same rates adaptively without prior knowledge of the data generating distribution.

Summary: Magnetic anomaly detection (MAD) is widely used for detecting magnetic targets, but its performance decreases in low signal-to-noise ratio (SNR) situations. To address this issue, we propose an adaptive MAD method using support vector machine (SVM) and validate its performance with real magnetic noise, showing improved detection performance compared to traditional methods.

Summary: This paper investigates how choice influences information gathering and finds that participants are more likely to sample information from a previously chosen alternative. The higher the confidence in the initial choice, the more biased the information sampling becomes. This phenomenon is controlled by agency and has a critical impact on the decision process.

Summary: This study introduces a stochastic optimization algorithm for the design optimization of a chain of resonators, considering both design and aleatory uncertainties, as well as addressing nonlinearities and reducing dimensionality through introducing a field formulation. The combination of the stochastic optimization algorithm and field representation leads to robust designs that cannot be achieved with optimal properties constant over the chain.

Summary: Some bowed string instruments, such as the cello or viola, are susceptible to a phenomenon called the wolf tone, caused by an interaction between resonance of the body and string motion, as well as Coulomb friction. Analysis of the eigenproblem and periodic solutions reveals the frequency veering phenomenon and the link between the bifurcations of periodic solutions and the appearance of the wolf tone.

Summary: Finite element-based crashworthiness optimization is widely used to improve the safety of motor vehicles. However, the high numerical noise in crash simulations poses challenges for surrogate-based design optimization. In this study, a non-deterministic kriging surrogate, called NDK, is proposed to model the noise-induced uncertainty. An optimization algorithm, incorporating both epistemic and irreducible aleatory uncertainty, is developed based on the NDK surrogate. The algorithm estimates the aleatory variance through variance kriging and iteratively refines the estimate.

Summary: This study investigated the impact of material uncertainty on acoustic source localization, considering the propagation of elastic waves and estimation of source location using wave front shape-based methods. The results showed that, under lognormal distributions, uncertainty in the modulus of elasticity in the major direction has a greater effect on source localization accuracy.
