Precise artificial intelligence is one of the most promising research fields, where supervised learning for spiking neurons (SNs) plays an imperative and fundamental role. This study proposes a novel supervised learning algorithm based on triple-spike train kernels to address the shortcomings of the latest learning algorithms, such as local best learning and low learning accuracy. First, we divided the time intervals of the spike trains, including the firing time of the input spikes. Subsequently, we discovered and analyzed the relationship between the firing times of all spikes, added a third spike to solve the existing problem, and constructed a triple-spike-driven (TSD) minimum direct computational unit. In addition to the simple and efficient adjustment of synaptic weights based on pair-spike, TSD maintains a relationship between all useful spikes to approximate the global best learning. Finally, we proposed a triple-spike train kernel driven (TSTKD) supervised learning algorithm to improve the learning performance. Many fundamental experiments were implemented to demonstrate the learning performance, which proved that the successful learning ability and some learning factors of our proposed algorithm in spike train learning. We then verified the positive effect of the TSD on the proposed algorithm. Many experiments also proved the much higher learning accuracy of the proposed state-of-the-art algorithm compared to some of the latest algorithms, especially in the complex spike train learning. In addition, the proposed algorithm is more adaptive to SNs and much better at generalizing, memorizing, and classifying than the corresponding algorithm with pair-spike and some of the latest algorithms. Considering the above experimental results, our study blazes a trail for pattern recognition using spike train supervised learning with global optimization.

Spiking neural network model encodes information with precisely timed spike train, it is very suitable to process complex spatiotemporal patterns. Recurrent spiking neural network has more complex dynamics characteristics because of feedback connections, which makes it difficult to design efficient learning algorithms. This paper proposes a supervised learning algorithm to train recurrent spiking neural networks. By mapping the integrate-and-fire neuron model to the rectified linear unit activation function, the learning rule is induced using error backpropagation and spike-timing dependent plasticity mechanism. The results of spike train learning task and non-linear pattern classification show that the algorithm is effective to learn spatiotemporal patterns. In addition, the influences of different parameters on learning performance are analyzed.

Recently, several numerical methods have been developed for solving time-fractional differential equations not only on rectangular computational domains but also on convex and non-convex non-rectangular computational geometries. On the other hand, due to the existence of integrals in the definition of space-fractional operators, there are few numerical schemes for solving space-fractional differential equations on irregular regions. In this paper, we develop a novel numerical solution based on the machine learning technique and a generalized moving least squares approximation for two-dimensional fractional PDEs on irregular domains. The scheme is constructed on the monomials, and this is the strength of this technique. Moreover, it will be used to approximate the space derivatives on convex and non-convex non-rectangular computational domains. The numerical results are extended to solve the fractional Bloch-Torrey equation, fractional Gray-Scott equation, and fractional Fitzhugh-Nagumo equation.

In the group decision-making process, experts and decision makers can sometimes provide subjective evaluation information with classification labels. To effectively deal with it and make a reasonable decision, two key issues should be addressed first, which include the information representation and consensus classification model in the above-mentioned uncertain information environment. To do so, this article extends the hesitant fuzzy set (HFS), which has been a hot and effective presentation tool in recent years, to the classification HFS (CHFS), the parallel HFS, and the parallel CHFS. Thus, we can mathematically present three types of evaluation information with classification labels or parallel characteristics in the consensus classification process. Then, to model the parallel classified hesitant fuzzy information and help further consensus classification, this article proposes a supervised learning algorithm and proves its generalization and optimization. In addition, based on the supervised learning algorithm and the obtained classification probability information, we develop a consensus classification method in the parallel classified hesitant fuzzy environment to derive the optimal consensus classification results. Finally, this article applies the proposed algorithm and methods to a real example of smart home system selection, which can show their rationality and feasibility.

As the popularity of the portable document format (PDF) file format increases, research that facilitates PDF text analysis or extraction is necessary. Heading detection is a crucial component of PDF-based text classification processes. This research involves training a supervised learning model to detect headings by systematically testing and selecting classifier features usingrecursive feature elimination. Results indicate that decision tree is the best classifier with an accuracy of 95.83%, sensitivity of 0.981, and a specificity of 0.946. This research into heading detection contributes to the field of PDF-based text extraction and can be applied to the automation of large scale PDF text analysis in a variety of professional and policy-based contexts.

The exploration of carbonate rocks has outstanding economic benefits, as well as facing the extreme challenge of reservoir characterization. This article has proposed a data-based description scheme generalizing carbonate pore-type characteristics from both laboratory measurements and theoretical predictions to the well logging dataset. Firstly, in the feature space of elastic properties, we employed the supervised machine learning (ML) algorithm to convert this pore-type classification process from a typical nonlinear inversion to sample label allocation problem. Secondly, to alleviate the inherent scale gaps between data sources, virtual samples were randomly mixed into the laboratory measured dataset. Through inheriting or mimicking statistical elastic features of limited core samples, the new built training dataset could improve the overall sample richness and thus help the ML algorithms making better identification decisions. On the one hand, this scheme was verified by 74 carbonate samples. In the feature space of high dimensions, the blended dataset trained radial basis function support vector machine accurately separated different carbonate pore systems. Moreover, using logging curves of a carbonate gas field, we verified the generalization capability of this scheme over unbalanced data scales. Searching skills were used to optimize model and classifier setups according logging curves of a specific interval. Finally, with the help of the vertical label distributions, logging elastic response modes and historical pore evolution footprints were further studied.

Several reasons such as no free lunch theorem indicate that there is nota universal Feature selection (FS) technique that outperforms other ones. Moreover, some approaches such as using synthetic dataset, in presence of large number of FS techniques, are very tedious and time consuming task. In this study to tackle the issue of dependency of estimation accuracy on the selected FS technique, a methodology based on the heterogeneous ensemble is proposed. The performance of the major learning algorithms of neural network (i.e. the FFNN-BR, the FFNN-LM) in combination with the diverse FS techniques (i.e. the NCA, the F-test, the Kendall's tau, the Pearson, the Spearman, and the Relief) and different combination techniques of the heterogeneous ensemble (i.e. the Min, the Median, the Arithmetic mean, and the Geometric mean) are considered. The target parameters/transients of Bushehr nuclear power plant (BNPP) are examined as the case study. The results show that the Min combination technique gives the more accurate estimation. Therefore, if the number of FS techniques is m and the number of learning algorithms is n, by the het-erogeneous ensemble, the search space for acceptable estimation of the target parameters may be reduced from n x m to n x 1. The proposed methodology gives a simple and practical approach for more reliable and more accurate estimation of the target parameters compared to the methods such as the use of synthetic dataset or trial and error methods.
