Traffic forecasting is one of the most difficult challenges in the area of ITS (intelligent transportation systems) because of complex spatial correlations on road networks and non-linear temporal dynamics of changing road conditions. To address these issues, researchers proposed models that combine GCNs (Graph Convolution Networks) and RNNs (Recurrent Neural Networks), in order to inherit the advantages of both of them and become capable of extracting spatiotemporal correlations. Restricting the efficiency of the models by their precision without concern for their structure made the models become more complex, although simple models sometimes produce better results. In this research, we introduce a simple model, called Long Short-Term Memory network for Traffic Forecasting (LSTM-TF), which uses the LSTM for extracting spatial-temporal dependencies. Experiments show that the LSTM-TF outperforms state-of-the-art baselines on real-world traffic datasets, proving our hypothesis that simple models as the LSTM-TF produce sometimes better results than more complex ones.
由于道路网络的复杂空间相关性和道路条件变化的非线性时间动态,交通预测是智能交通系统领域最困难的挑战之一。为了解决这些问题,研究人员提出了结合GCNs(图卷积网络)和RNNs(递归神经网络)的模型,以继承两者的优点,并能够提取时空相关性。以精度限制模型的效率而不考虑模型的结构会使模型变得更加复杂,尽管简单的模型有时会产生更好的结果。在本研究中,我们引入了一个简单的模型,称为交通预测的长短期记忆网络(LSTM- tf),它使用LSTM来提取时空依赖性。实验表明,LSTM-TF在真实交通数据集上的表现优于最先进的基线,证明了我们的假设,即LSTM-TF这样的简单模型有时比更复杂的模型产生更好的结果。

During the last few years, deep learning revolutionized several fields including: image analysis, speech recognition and language processing. Deep learning has also become pervasive and demonstrated effectiveness in the field of recommender systems and information retrieval. Unlike the conventional recommendation systems, deep learning have the unique ability to successfully capture non-trivial and non-linear interactions between user and item, allowing for the codification of more complicated abstractions. We begin by providing a brief overview of recommender systems and deep learning. Second, we present a complete overview of the current state of the art in deep learning-based RS. Then, we describe a possible future research direction of the field. Finally, we conclude the review.

Several algorithms for target recognition in infrared images were proposed by reasearchers to develop an efficient advanced driver assistance systems. In this paper, an approach based on bag of features framework, SIFT and SVM, is evaluated for target recognition problem. First, SIFT extractor is applied to all the training set. Then, features were clustered by K-means; the cluster centers are regarded as visual words to form a visual vocabulary. For each image, a histogram of quantized local descriptors is computed according to the frequency of visual words in each sub-region, which are obtained by the spatial pyramid matching technique. The generated feature vector will be mapped for later use as an input to SVM. Extensive experiments are carried out in FLIR dataset. Our experimental results show that the proposed method exceeds the-state-of-art in target recognition on two class FLIR dataset with 3% improvement in accuracy classification.

In designing engineering systems, definitive solutions can hardly be applied to actual scenarios. This issue is mainly originated from production constraints and the environmental conditions of the actual systems under exploitation. Therefore, a small change in the design variables vector may lead to a significant change in the optimal design that minimizes the objective functions. Hence, it is important to develop methods that provide optimal (or even sub-optimal) solutions with less sensitivity to the uncertainty of the design variables. This is the focus of this paper. We present a robust Non-dominated-Sorting Genetic Algorithm II (NSGA-II)-based multi-objective constrained optimization algorithm. To further illustrate the method, the proposed algorithm is used in the robust and constrained optimal design of a sample engineering system. Evaluation of the obtained results shows that multi-objective engineering problems can be solved by the multi-objective robust optimization (MORO) through finding Pareto solutions, so that by changing the problem parameters, the changes of the solutions will be within an acceptable range.
在设计工程系统时,确定的解决方案很难应用于实际场景。这一问题主要源于生产约束和实际开发系统的环境条件。因此,设计变量向量的微小变化可能导致最小化目标函数的最优设计的显著变化。因此,开发对设计变量的不确定性敏感性较低的最优(甚至次最优)解决方案的方法是很重要的。这是本文的重点。提出了一种鲁棒非支配排序遗传算法II (NSGA-II)的多目标约束优化算法。为了进一步说明该方法,将该算法应用于一个样本工程系统的鲁棒约束优化设计。对所得结果的评价表明,多目标鲁棒优化(MORO)方法可以通过寻找Pareto解来求解多目标工程问题,使得通过改变问题参数,解的变化量在可接受的范围内。

Molecular classification in pathological anatomy is an important task as it is extremely convenient for the diagnosis of cancer and its subtypes for adequate therapeutic choice. With the development of computer vision, cancer classification has become an interdisciplinary subject in both medicine and computer vision.A multi-input convolutional neural network is designed for the molecular classification of cancer based on a collected dataset, which contains four tissues treated with four antibodies; each one of them is composed of 33 images. The proposed model achieves a satisfactory accuracy of 90.43% after data augmentation. Even though the data augmentation contributes to the model, the accuracy is still limited by the lack of sample diversity.

Exploiting Cyber Threat Intelligence (CTI) as a valuable, updated, and structured source of information on threats and vulnerabilities can be a strong support for providing effective cybersecurity solutions. CTIs are shared across dedicated online platforms via a machine-readable format, such as Structured Threat Information eXpression (STIX). Meanwhile, ontology-based semantic knowledge modeling has become a promising solution that provides a machine-readable language for downstream work to address cybersecurity issues. Hence, by incorporating STIX concepts we propose in this paper an ontological-based CTI analysis that provides valuable threats information according to the security alerts reported by an analyzer. To test our ontology, we developed a set of reasoning rules to infer new knowledge on cyber threats. The experimental results show that such knowledge can be inferred by applying our approach for an ongoing and effective monitoring of cyber threats.
利用网络威胁情报(CTI)作为一种有价值的、更新的、结构化的威胁和漏洞信息来源,可以为提供有效的网络安全解决方案提供强有力的支持。cti通过机器可读格式在专用在线平台上共享,例如结构化威胁信息表达(STIX)。同时,基于本体的语义知识建模已经成为一种很有前途的解决方案,它为下游工作提供了一种机器可读的语言来解决网络安全问题。因此,通过结合STIX概念,我们在本文中提出了一种基于本体论的CTI分析,根据分析器报告的安全警报提供有价值的威胁信息。为了测试我们的本体,我们开发了一套推理规则来推断关于网络威胁的新知识。实验结果表明,通过应用我们的方法对网络威胁进行持续有效的监测,可以推断出这些知识。

Free vibrations of liquid in the annular region of a rigid circular cylindrical container with a rigid baffle on the free surface are considered. The liquid inside the container is considered; ideal and incompressible, and the fluid motion is irrotational. In the above-considered geometry, along with assumptions made, the velocity potential is introduced, which satisfies Laplace’s equation inside the liquid domain. The boundary value problem (BVP) is formulated using the linear water wave theory. The analytical solution of BVP is obtained in terms of velocity potential with unknown frequency. The velocity potential is used in free surface conditions, which results in a system of homogeneous algebraic equations. The necessary condition for a non-trivial solution of this homogenous system is used to compute the frequencies. Mode shapes of the container in the presence of a rigid baffle are reported using ANSYS software.

The operation of demand and supply in a market is known as the market mechanism. The market will be in equilibrium at price (P), when quantity (Q) will be bought and sold. In equilibrium the quantity of a good supplied by producers equals the quantity demanded by consumers. Due to the fact that traditional deterministic methods or algorithms do not cope well to solve a large number of problems in practice; The aim of this paper is to solve approximately the demand and supply equilibrium equation which has an imperative role to describe the relation between consumers/ producers and price/quantity by means of the Salp Swarm Algorithm (SSA), inspired by the swarming behavior of salps when searching foods in deep oceans as well as the Genetic Algorithm (GA) inspired by the process of natural selection. The demand and supply equilibrium equation as an Initial Value Problem (IVP) is considered as an optimization problem, since it can almost be solved by classical mathematical tools with less precision. The effectiveness of the proposed method is tested via a simulation study between the exact results, the SSA and GA results. The comparison between these performances after many replications shows that SSA is a very powerful and can produce robust solutions on low dimensional problems with minimal error.
市场中需求和供给的运行被称为市场机制。当数量(Q)被买卖时,市场在价格(P)处处于均衡状态。在均衡状态下,生产者提供的某种商品的数量等于消费者的需求量。由于传统的确定性方法或算法不能很好地解决实际中的大量问题;本文的目的是利用受深海中Salp寻找食物的群体行为启发的Salp Swarm算法(SSA)和受自然选择过程启发的遗传算法(GA),近似求解对描述消费者/生产者和价格/数量关系有重要作用的供需平衡方程。需求和供给平衡方程作为一个初值问题(IVP)被认为是一个优化问题,因为它几乎可以用经典的数学工具来求解,但精度较低。通过对精确结果、SSA和GA结果的仿真研究,验证了该方法的有效性。在多次重复之后,对这些性能的比较表明,SSA是一种非常强大的方法,可以以最小的误差产生低维问题的鲁棒解。
