Water distribution system (WDS) is one of the most essential infrastructures all over the world. However, incidents such as natural disasters, accidents and intentional damages are endangering the safety of drinking water. With the advance of sensor technologies, different kinds of sensors are being deployed to monitor operative and quality indicators such as flow rate, pH, turbidity, the amount of chlorine dioxide etc. This brings the possibility to detect anomalies in real time based on the data collected from the sensors and different kinds of methods have been applied to tackle this task such as the traditional machine learning methods (e.g. logistic regression, support vector machine, random forest). Recently, researchers tried to apply the deep learning methods (e.g. RNN, CNN) for WDS anomaly detection but the results are worse than that of the traditional machine learning methods. In this paper, by taking into account the characteristics of the WDS monitoring data, we integrate sequence-to-point learning and data balancing with the deep learning model Long Short-term Memory (LSTM) for the task of anomaly detection in WDSs. With a public data set, we show that by choosing an appropriate input length and balance the training data our approach achieves better F1 score than the state-of-the-art method in the literature.
配水系统是世界各国最重要的基础设施之一。然而,自然灾害、事故和故意破坏等事件正在危及饮用水安全。随着传感器技术的进步,不同类型的传感器被用于监测操作和质量指标,如流量、pH值、浊度、二氧化氯量等。这带来了基于从传感器收集的数据实时检测异常的可能性,并且已经应用了不同类型的方法来解决此任务,例如传统的机器学习方法(例如逻辑回归,支持向量机,随机森林)。近年来,研究人员尝试将深度学习方法(如RNN、CNN)应用于WDS异常检测,但效果不如传统的机器学习方法。本文结合WDS监测数据的特点,将序列到点学习和数据平衡与深度学习模型长短期记忆(LSTM)相结合,用于WDS异常检测任务。对于公共数据集,我们表明,通过选择适当的输入长度和平衡训练数据,我们的方法比文献中最先进的方法获得了更好的F1分数。

The circular economy follows the principle of reducing resource usage and energy consumption, reusing usable resources including subassemblies and components in discarded or used products, and recycling usable materials. It is guided by saving resources, improving the utilization rate of resources, reducing pollution, and protecting an ecological environment. Effective product disassembly planning methods can improve recovery efficiency and promote the circular economy. However, the existing studies pay little attention to sequential dependency disassembly, which makes it difficult to implement the existing planning methods under the constraints of limited disassembly methods and tools. In this paper, a single-objective sequence-dependent disassembly line balancing problem (SDLB) is studied. This problem requires that disassembly tasks are assigned to a group of orderly disassembly workstations to obtain the near optimal solution while meeting a disassembly priority constraint. Because solution complexity increases with the number of parts in a product, an improved artificial bee colony method (IABC) is proposed to solve the problem. Through experiments and compared with a genetic algorithm, the effectiveness of the proposed algorithm is verified.
循环经济遵循的原则是减少资源使用和能源消耗,再利用废弃或使用过的产品中的可用资源,包括组件和部件,回收利用可用材料。它以节约资源、提高资源利用率、减少污染、保护生态环境为指导。有效的产品拆解规划方法可以提高回收效率,促进循环经济。然而,现有的研究很少关注顺序依赖关系的拆卸,这使得现有的规划方法在有限的拆卸方法和工具的约束下难以实现。研究了单目标序列相关拆解线平衡问题。该问题要求将拆卸任务分配给一组有序的拆卸工作站,以在满足拆卸优先级约束的情况下获得接近最优解。针对求解复杂度随产品零件数量的增加而增加的问题,提出了一种改进的人工蜂群法(IABC)。通过实验并与遗传算法进行比较,验证了该算法的有效性。

with a variety of new energy access to the power grid, its frequency control is facing many new challenges, and the demand response resources play an increasingly important role in FM (frequency modulation). In this paper, the intermittent characteristics of demand response resource is described, which is determined by the user's comfort and the physical characteristics of the demand response resources themselves. For example, air conditionings are disconnected for a period of time to maintain constant room temperature. Electric vehicle need to charge themselves after participating in the frequency response. The intermittent characteristics will reduce the performance of frequency control without coordination. Thus the coordination strategy will be designed for diffident demand response resources based on switch control method. And the simulation results show the effectiveness of the coordination strategy.
随着各种新能源接入电网,其频率控制面临着许多新的挑战,需求响应资源在调频中发挥着越来越重要的作用。本文描述了需求响应资源的间歇性特性,这是由用户的舒适度和需求响应资源本身的物理特性决定的。例如,将空调断开一段时间以保持室温恒定。电动汽车参与频率响应后需要自行充电。频率控制的间歇性会降低无协调频率控制的性能。在此基础上,设计了基于开关控制方法的需求响应资源不确定的协调策略。仿真结果表明了该协调策略的有效性。

Power equipment inspection is one of the most important tasks to guarantee safe and stable operation of power grids. Although traditional power equipment detection methods are simple, their performances are not stable under complex outdoor environments. In this paper, we integrated the LSTM structure into the Faster R-CNN network, and designed a Faster LSTM-CNN network. We collected both normal samples and special samples, and used a variety of identification neural network models to conduct various experiments. The experimental results show that, compared with other methods such as Faster R-CNN and R-FCN, the proposed Faster LSTM-CNN network has better recognition performance for both normal samples and special samples.

Textile industry has become the third largest energy consuming industry after engineering and chemical sectors. In order to reduce the energy consumption in the textile industry, a neural network is used to establish the energy consumption prediction model of the winder. In this research, the model is specially designed as the objective function to optimize the energy consumption of the winders. Firstly, the neural network error back propagation is analyzed and the absolute values of the weight coefficient matrix product are used to approximate the influence of input parameters on the model output. The values are also used to select the core parameters to optimize the model. Secondly, the single-dimensional search method is applied for a set of parameter values within a reasonable interval of the whole input parameters to reduce the energy consumption. Experimental results indicate that a set of core parameters can be determined to remodel after the training of the neural network model. In addition, a set of parameter values obtained by single-dimensional search can also be used to effectively reduce the energy consumption of the winders. The proposed method effectively solves the problem and is efficient and straightforward. The feasibility of the proposed approach is validated through the comparative analysis.

An Initialization Method of Deep Q-network for Learning Acceleration of Robotic Grasp 机器人抓取加速学习的深度q网络初始化方法

Generally, self-supervised learning of robotic grasp utilizes a model-free Reinforcement Learning method, e.g., a Deep Q-network (DQN). A DQN makes use of a high-dimensional Q-network to infer dense pixel-wise probability maps of affordances for grasping actions. Unfortunately, it usually leads to a time-consuming training process. Inspired by the initialization thought of optimization algorithms, we propose a method of initialization for accelerating self-supervised learning of robotic grasp. It pre-trains the Q-network by the supervised learning of affordance maps before the robotic grasp training. When applying the pre-trained Q-network a robot can be trained through self-supervised trial-and-error in a purposeful style to avoid meaningless grasping in empty regions. The Q-network is pre-trained by supervised learning on a small dataset with coarse-grained labels. We test the proposed method with Mean Square Error, Smooth L1, and Kullback-Leibler Divergence (KLD) as loss functions in the pre-training phase. The results indicate that the KLD loss function can predict accurately affordances with less noise in the empty regions. Also, our method is able to accelerate the self-supervised learning significantly in the early stage and shows little relevance to the sparsity of objects in the workspace.
一般来说,机器人抓取的自监督学习采用无模型强化学习方法,例如Deep Q-network (DQN)。DQN利用高维q网络来推断抓取动作的可视性的密集逐像素概率图。不幸的是,这通常会导致一个耗时的培训过程。受优化算法初始化思想的启发,提出了一种加速机器人抓取自监督学习的初始化方法。在机器人抓握训练之前,通过对可视性图的监督学习对q网络进行预训练。当应用预训练的q网络时,机器人可以通过有目的的自监督试错来训练,以避免在空白区域无意义的抓取。q网络通过监督学习在一个带有粗粒度标签的小数据集上进行预训练。我们在预训练阶段用均方误差、平滑L1和Kullback-Leibler散度(KLD)作为损失函数来测试所提出的方法。结果表明,KLD损失函数可以准确地预测空区域的性能,并且噪声较小。此外,我们的方法能够在早期阶段显著加速自监督学习,并且与工作空间中对象的稀疏性无关。

Cloud computing attracts a growing number of organizations to deploy their applications in distributed data centers for low latency and cost-effectiveness. The growth of arriving instructions makes it challenging to minimize their energy cost and improve Quality of Service (QoS) of applications by optimizing resource provisioning and instruction scheduling. This work formulates a bi-objective constrained optimization problem, and solves it with a Simulated-annealing-based Adaptive Differential Evolution (SADE) algorithm to jointly minimize both energy cost and instruction response time. The minimal Manhattan distance method is adopted to obtain a knee for good tradeoff between energy cost minimization and QoS maximization. Real-life data-based experiments demonstrate SADE achieves lower instruction response time, and smaller energy cost than several state-of-the-art peers.
云计算吸引了越来越多的组织将其应用程序部署在分布式数据中心,以实现低延迟和低成本效益。到达指令的增长使得通过优化资源供应和指令调度来最小化它们的能量成本和提高应用程序的服务质量(QoS)变得具有挑战性。本文提出了一个双目标约束优化问题,并采用一种基于模拟退火的自适应差分进化(SADE)算法对其进行求解,从而使能量消耗和指令响应时间同时最小化。采用最小曼哈顿距离法,在能量成本最小化和QoS最大化之间获得一个较好的平衡点。现实生活中基于数据的实验表明,与几个最先进的同行相比,SADE实现了更低的指令响应时间和更小的能量消耗。

Most face recognition studies are based on standard frontal face databases, but in real life, the images we obtain are profile face images of any angle in most instances. In this case, the traditional face recognition methods cannot achieve the lowest recognition cost. Therefore, how to use the obtained profile face images to synthesize the corresponding frontal face images is important in the face recognition system. Besides, most traditional face recognition systems are try to find an accurate classifier to achieve the lowest error rate, implicitly assuming that all misclassification costs are equal. It is an unreasonable assumption because almost in all face recognition systems, different types of misclassification errors often lead to different misclassification costs. To address the two issues, we propose a cost-sensitive face recognition method based on generative adversarial nets. First, generate frontal face images using the two-channel generative adversarial nets, and then introduce cost-sensitive learning in the recognition process to consider the cost imbalance problem. The experimental results demonstrate the effectiveness of the proposed method.
大多数人脸识别研究都是基于标准的正面人脸数据库,但在现实生活中,大多数情况下我们获得的是任意角度的侧面人脸图像。在这种情况下,传统的人脸识别方法无法达到最低的识别成本。因此,如何利用获得的侧面人脸图像合成相应的正面人脸图像在人脸识别系统中是很重要的。此外,大多数传统的人脸识别系统都试图找到一个准确的分类器,以达到最低的错误率,隐含地假设所有的错误分类成本是相等的。这是一个不合理的假设,因为几乎在所有的人脸识别系统中,不同类型的误分类错误往往导致不同的误分类代价。为了解决这两个问题,我们提出了一种基于生成对抗网络的代价敏感人脸识别方法。首先,利用双通道生成对抗网络生成正面人脸图像,然后在识别过程中引入代价敏感学习,考虑代价不平衡问题。实验结果证明了该方法的有效性。
