Muhammad Muneeb Saad, Talha Iqbal, Hazrat Ali, Mohammad Farhad Bulbul, Shahid Khan, C. Tanougast
Artificial Intelligence (AI) techniques provide many intelligent methods for security solutions in various domains such as finance, networking, cloud computing, health records and individual's identity. AI achieves security mechanisms like antivirus, firewalls, intrusion detection system (IDS) and cryptography by using machine learning methods and data analysis techniques. As the modern AI techniques help improving security systems, criminal activities are also becoming updated simultaneously. Machine learning methods along with data analysis tools have become popular to prevent security systems from threats and hacking activities. This work contributes to secure cloud networks and help them prevent malicious attacks. In this paper, Bidirectional long short-term memory (BLSTM) is used to detect incidents over unified threat management (UTM) platform operated on cloud network. Results are compared with K-nearest neighbor which is a baseline technique. Time series input samples recorded over UTM platform are used for training and testing purposes. We obtain accuracy score of 98.47% with 0.0186 mean squared error (MSE) using KNN while BLSTM provides 98.6% accuracy score with 0.002 loss, which is better than the KNN.

In the paper, the 2D-deep neural network and the algorithm for its online learning are proposed. This system allows reducing the number of adjustable weights due to the rejection of the vectorization-devectorization operations. As a result, it saves the information that is contained between columns and rows of data inputs presented as 2D matrix.

A Fast and Accurate Edge Detection Algorithm for Real-Time Deep-Space Autonomous Optical Navigation 一种用于实时深空自主光学导航的快速精确边缘检测算法
Hao Xiao, Yanming Fan, Zhang Zhang, Xin Cheng
This paper presents a fast and accurate edge detection algorithm for real-time autonomous optical navigation used in deep-space missions. The proposed algorithm optimizes the non-maximum suppression (NMS) mechanism and the adaptive threshold selection approach of the conventional Canny algorithm. Instead of computing gradient directions, the proposed NMS approach adopts the vertical and horizontal gradients to determine the diagonal directions of gradient directions. In addition, an optimized noise edge suppression mechanism is presented for getting thinner edges without sacrificing the performance in terms of computation complexity. Furthermore, unlike the conventional double-thresholding method, this paper proposes a single-threshold selection approach, thus reducing the computational complexity and easing the real-time embedded implementation. More importantly, the proposed single-threshold scheme can efficiently suppress the noise edges caused by craters and atmosphere covered on celestial bodies. Experimental results show that, compared with the traditional Canny edge detector, the proposed algorithm enables more accurate celestial body edge detection, while reducing a lot of computation complexity.
提出了一种用于深空实时自主光学导航的快速、准确的边缘检测算法。该算法对传统Canny算法的非最大抑制机制和自适应阈值选择方法进行了优化。本文提出的NMS方法不计算梯度方向,而是采用垂直和水平梯度来确定梯度方向的对角线方向。此外,提出了一种优化的噪声边缘抑制机制,在不牺牲计算复杂度的情况下获得更薄的边缘。此外,与传统的双阈值选择方法不同,本文提出了一种单阈值选择方法,从而降低了计算复杂度,简化了实时嵌入式实现。更重要的是,所提出的单阈值方案可以有效地抑制天体上覆盖的陨石坑和大气所产生的噪声边缘。实验结果表明,与传统的Canny边缘检测器相比,该算法能够更精确地检测天体边缘,同时大大降低了计算复杂度。

Feng Chen, Z. Ye, Jun Su, Haofeng Lang, Xiaoxiao Shi, Shuqing Wang
In order to provide users with reliable and qualified power, it becomes an indispensable task to enhance the forecasting capability of the short-term power load. However, the existing approaches of short-term electric load forecasting are not proper enough. A short-term electric load forecasting method based on grey neural network based on snap-drift cuckoo search optimization algorithm(SDCS-GNN) is proposed in this paper. Parameters of gray neural network (GNN) are selected randomly which is similar to the initial spatial position of birds' eggs in the parasitic nest of cuckoo. The SDCS is utilized to search the better weight and threshold of the conventional gray neural network (GNN), which improves the stability and accuracy of the prediction model. To validate the superior performance of the proposed method, several well-known evolutionary algorithms such as particle swarm optimization (PSO), grey wolf optimization(GWO), moth-fire suppression optimization(MFO) and cuckoo search optimization (CS) are employed to constitute the contrast experiment of the prediction of short-term power load. The mean squared error predicted by the SDCS-GNN model is the smallest, which compared with GNN, PSO-GNN, GWO-GNN, MFO-GNN, and CS-GNN is 0.36, 1.79, 15.23, 4.53, 2.93, respectively. The Average prediction accuracy of SDCS-GNN model is better than other models which is 7.1592, 1.427, 15.1516, 11.5438, 10.5202, respectively. The simulation results show that the SDCS-GNN model has better approximation ability and higher prediction accuracy than the conventional GNN and other evolutionary algorithms in the short-term electric load forecasting. The experiments above indicates that the prediction method is effective and feasible.
为了向用户提供可靠、合格的电力,提高短期电力负荷的预测能力成为不可缺少的任务。但是,现有的短期负荷预测方法还不够完善。提出了一种基于瞬时漂移布谷鸟搜索优化算法(SDCS-GNN)的灰色神经网络短期电力负荷预测方法。灰色神经网络(GNN)的参数随机选取,类似于杜鹃寄生巢中鸟蛋的初始空间位置。利用SDCS来搜索传统灰色神经网络(GNN)更好的权值和阈值,提高了预测模型的稳定性和准确性。为了验证所提方法的优越性能,采用粒子群优化(PSO)、灰狼优化(GWO)、蛾火抑制优化(MFO)和布谷鸟搜索优化(CS)等几种著名的进化算法对短期电力负荷进行预测对比实验。与GNN、PSO-GNN、GWO-GNN、MFO-GNN和CS-GNN相比,SDCS-GNN模型预测的均方误差最小,分别为0.36、1.79、15.23、4.53、2.93。SDCS-GNN模型的平均预测精度分别为7.1592、1.427、15.1516、11.5438、10.5202,优于其他模型。仿真结果表明,在短期电力负荷预测中,SDCS-GNN模型比传统的GNN及其他进化算法具有更好的逼近能力和更高的预测精度。以上实验表明,该预测方法是有效可行的。

Dawei Dong, Z. Ye, Yu Cao, Shiwei Xie, Fengwen Wang, Wei Ming
Discovering knowledge from the amount of data plays an important role in the era of big data and FP-Growth algorithm is one of the most successful methods for learning association rules. Though the FP-Growth algorithm only needs scan two times, it has a poor efficiency for large datasets. There are already efforts have been made to solve the problem by using some Meta-heuristic optimization algorithms, such as particle swarm optimization algorithm (PSO), immune algorithms etc, which outperform the traditional FP-Growth algorithm and shows strong performance. However, PSO is easy to trap in the local optimums. A novel algorithm ant lion optimizer (ALO) was proposed and with the advantages of global optimization, good robustness, and high convergence accuracy, which was applied to many engineering fields like antenna array synthesis, integrated process planning, scheduling and so on. In the paper, a novel association rule extraction algorithm is put forward based on the ant lion optimization algorithm. A new fitness schema based on confidence and support has been used in this approach, which avoids part of unnecessary searching processes of the FP-Growth algorithm and leads the method of searching the optimization solution more effectively. In order to evaluate the effectiveness of our approach, experiments on various datasets are carried out and experimental results are compared with some other classical meta-heuristic algorithms, experimental results testify the performance of the proposed method.
在大数据时代,从海量数据中发现知识发挥着重要作用,FP-Growth算法是学习关联规则最成功的方法之一。虽然FP-Growth算法只需要扫描两次,但对于大型数据集来说,它的效率很低。一些元启发式优化算法,如粒子群优化算法(PSO)、免疫算法等,已经在解决这一问题上做出了努力,这些算法优于传统的FP-Growth算法,表现出较强的性能。然而,粒子群算法容易陷入局部最优。提出了一种新的蚁群优化算法(ALO),该算法具有全局寻优、鲁棒性好、收敛精度高等优点,已广泛应用于天线阵综合、综合工艺规划、调度等工程领域。在蚁狮优化算法的基础上,提出了一种新的关联规则提取算法。该方法采用了一种新的基于置信度和支持度的适应度模式,避免了FP-Growth算法中部分不必要的搜索过程,提高了搜索最优解的效率。为了评估该方法的有效性,在不同的数据集上进行了实验,并将实验结果与其他经典的元启发式算法进行了比较,实验结果证明了该方法的有效性。

M. Yesina, M. Karpinski, V. Ponomar, Y. Gorbenko, T. Gancarczyk, Uliana Yatsykovska
The paper deals with the possible comparative analysis methods of the cryptographic primitives' properties. Methods of comparative analysis – analytic hierarchy process and variations of weight indices methods are investigated and analyzed. Conclusions are made and recommendations on the use of the cryptographic primitives' estimation methods are provided. Also the paper is devoted to the comparative analysis of candidates for the post-quantum key encapsulation standard according to the determined estimation technique. During the analysis, the technique of comparing cryptographic algorithms on the basis of expert estimations using the combination of conditional and unconditional criteria by the analytic hierarchy process was used.
