Evolutionary Ensemble LSTM based Household Peak Demand Prediction 基于进化集成LSTM的家庭峰值需求预测
Songpu Ai, Antorweep Chakravorty, Chunming Rong
The popularization of electric vehicle, the commercialization of micro-generation, and the advance of local storage lead great challenges to the local power grid on household and neighbourhood level. A potential solution is to construct a home/neighbourhood energy management system (HEMS) to coordinate all available electrical equipment together using AI. As a portion of HEMS, peak demand prediction is critically important on triggering load scheduling among the household power environment to achieve better electricity usage curve. Long short-term memory (LSTM) network as an eminent type of machine learning method is generally considered to be capable on forecasting based on time series data including temporal dynamic behaviours with unknown lags. Various LSTM networks are adopted in existing researches to provide predictions in energy informatics field. However, the presented network structures are commonly selected through empirical or enumerative approaches. The utilized networks are generally carefully tuned as case by case studies. In this article, an evolutionary ensemble LSTM (EELSTM) method is proposed to pool LSTM networks with the same structure or with similar structures to obtain a more reliable prediction automatically. Experimental study demonstrates that networks with suitable structures and initialization are selected out through the learning process. A better performed peak demand prediction is achieved comparing with single LSTM unit network. In addition, the evolutionary parameters have variant impacts on the model performance.
电动汽车的普及、微型发电的商业化以及局部储能的推进,给家庭和小区一级的局部电网带来了巨大的挑战。一个潜在的解决方案是构建一个家庭/社区能源管理系统(HEMS),利用人工智能协调所有可用的电气设备。高峰需求预测作为HEMS的一部分,对于触发家庭用电环境中的负荷调度以获得更好的用电曲线至关重要。长短期记忆(LSTM)网络作为一种杰出的机器学习方法,通常被认为能够基于时间序列数据(包括未知滞后的时间动态行为)进行预测。现有研究采用了多种LSTM网络来提供能源信息学领域的预测。然而,所提出的网络结构通常是通过经验或枚举方法选择的。所使用的网络通常是根据具体案例进行仔细调整的。本文提出了一种进化集成LSTM (EELSTM)方法,将具有相同结构或相似结构的LSTM网络进行池化,自动获得更可靠的预测结果。实验研究表明,在学习过程中选择出合适的网络结构和初始化。与单LSTM单元网络相比,实现了更好的峰值需求预测。此外,演化参数对模型性能有不同的影响。

Tracking User Application Activity by using Machine Learning Techniques on Network Traffic 在网络流量上使用机器学习技术跟踪用户应用程序活动
Sina Fathi Kazerooni, Yagiz Kaymak, R. Rojas-Cessa
A network eavesdropper may invade the privacy of an online user by collecting the passing traffic and classifying the applications that generated the network traffic. This collection may be used to build fingerprints of the user’s Internet usage. In this paper, we investigate the feasibility of performing such breach on encrypted network traffic generated by actual users. We adopt the random forest algorithm to classify the applications in use by users of a campus network. Our classification system identifies and quantifies different statistical features of user’s network traffic to classify applications rather than looking into packet contents. In addition, application classification is performed without employing a port mapping at the transport layer. Our results show that applications can be identified with an average precision and recall of up to 99%.

A layer-wise Perturbation based Privacy Preserving Deep Neural Networks 一种基于分层扰动的隐私保护深度神经网络
Tosin A. Adesuyi, Byeong-Man Kim
Datasets are sources of information mining where knowledge can be derived. The versatility of these dataset determines the quality of knowledge gained. However, several of these data contains personal sensitive information that can lead to infringement of privacy. Existing research tends to deliver DNN models that can preserve privacy of personal information but the accuracy of these models are rather much lower as compared to their non-privacy preserving counterparts. This is due to the degree of noise and the points where noise was added to perturb the model data. Consequently, this has led to minimal adoption of privacy preserving DNN models in the industrial world. In this paper, we present a layer-wise perturbation approach and differential privacy technique to determine points of perturbation and preserve privacy. Our approach was able to narrow down the accuracy gap between privacy-preserving and non-privacy preserving DNN model.
数据集是信息挖掘的来源,可以从中获得知识。这些数据集的多功能性决定了所获得知识的质量。然而,其中一些数据包含可能导致侵犯隐私的个人敏感信息。现有的研究倾向于提供能够保护个人信息隐私的深度神经网络模型,但与非隐私保护模型相比,这些模型的准确性要低得多。这是由于噪声的程度和添加噪声来干扰模型数据的点。因此,这导致在工业世界中很少采用保护隐私的DNN模型。在本文中,我们提出了一种分层摄动方法和差分隐私技术来确定摄动点并保护隐私。我们的方法能够缩小隐私保护和非隐私保护DNN模型之间的准确性差距。

Deep Learning for Polar Codes over Flat Fading Channels 平坦衰落信道上极点码的深度学习
A. Irawan, G. Witjaksono, W. Wibowo
This paper proposes a deep-neural-networks scheme for decoding polar coded short packets. We consider packet transmission over frequency-flat quasi-static Rayleigh fading channels, where the channel coefficient is constant over a packet but changes packet-by-packet. Potential applications of the proposed technique are machine-type communications, messaging services, smart metering networks, and other wireless sensor networks requiring high reliability and low-latency. Computer simulations results confirm that even with simple codebook construction for an additive white Gaussian noise (AWGN) channel without fading, the proposed technique closes to the theoretical outage and achieves the coding gain in fading channel. Analyses of the learning epochs and training signal-to-noise power ratio (SNR) selections are also presented to demonstrate the effectiveness of the technique.

Framework of Big data Analysis about IoT-Home-device for supporting a decision making an effective strategy about new product design 物联网家庭设备大数据分析框架,支持新产品设计决策制定有效策略
Jong-jin Jung, Kyung Won Kim, Jongbin Park
This paper introduces a framework of big data analysis about IoT home devices which are delivered to the consumer through several distribution channels, are used by a home user in the smart home, and are repaired in A/S center (repair shop). We collect big data and make an analysis at three major stages that are distribution stage, customer-usage stage, and A/S stage. The ultimate purpose of the presented framework is to help the small/medium companies to make an elastic strategy for the new product. Therefore they can make a more effective decision at three major stages. For example, they can reduce redundancy about a distribution channel, they can adjust a quantity of warehousing, release, stock. They can make a decision on what to upgrade the new next device, how to increase durability, and so on. For these purposes, this framework consists of three subsystems. 1) A data crawler that collects and stores big data about IoT-home devices at three major stages, 2) A big data analyzer about IoT-home device with an appreciate analytic model, 3) A visualization of insights, which help a user to understand the analytic output.

Object Management Based on Metadata Registry for Intelligent Mobile Augmented Reality 基于元数据注册的智能移动增强现实对象管理
S. Jang
An intelligent mobile augmented reality (IMAR) can be a useful scheme when users want get additional information about products or objects in a store. One of the problems to be resolved in the service is how to manage huge number of augmented objects. One of the approaches is to separate object's metadata from real objects. By doing this, we can reduce amount of storage and object searching time. However, to apply such scheme seamlessly, we have to well organize each object's metadata and store them efficiently. To do this, this paper present a scheme that is based on metadata registry (MDR). In the scheme, all objects are organized in the ways specified by MDR standards.

Multi-Channel Audio Source Separation Using Azimuth-Frequency Analysis and Convolutional Neural Network 基于方位频率分析和卷积神经网络的多声道音频源分离
J. M. Moon, C. Chun, Jun Ho Kim, H. Kim, Tae Kim
Since MPEG-H supports not only channel-based but also object-based audio content, there is a need for a sound source separation technique that converts channel-based to object-based audio. Among the various sound source separation techniques, azimuth-frequency (AF) based sound source separation has been proposed for converting channel-based audio to object-based audio. Unfortunately, it is difficult to set the optimal azimuth and width using this technique. In this paper, we propose a method to determine the optimal azimuth and width based on a convolutional neural network (CNN) classifier. First, depending on numerous azimuths and widths, different sets of audio signals are separated. After that, each audio set is categorized into a specific audio class using the CNN classifier. Then, in order to separate a desired audio signal, the azimuth and width with the highest similarity for a given class are selected. The performance of the CNN classifier is evaluated in terms of separation accuracy and objective measures such as signal-to-distortion ratio (SDR), signal-to-interference ratio (SIR), and signal-to-artifacts ratio (SAR). Consequently, the proposed method provides higher SDR, SAR, SIR, and separation accuracy than a minimum variance distortionless response (MVDR) beamformer as well as a method that only uses AF analysis.
由于MPEG-H不仅支持基于声道的音频内容,也支持基于对象的音频内容,因此需要一种声源分离技术,将基于声道的音频转换为基于对象的音频。在各种声源分离技术中,基于方位角频率(AF)的声源分离技术被提出用于将基于通道的音频转换为基于对象的音频。不幸的是,使用这种技术很难设置最佳的方位角和宽度。在本文中,我们提出了一种基于卷积神经网络(CNN)分类器来确定最佳方位和宽度的方法。首先,根据许多方位角和宽度,分离不同的音频信号集。之后,使用CNN分类器将每个音频集分类到特定的音频类中。然后,为了分离期望的音频信号,选择给定类中相似度最高的方位角和宽度。CNN分类器的性能是根据分离精度和客观指标(如信号失真比(SDR)、信号干扰比(SIR)和信号伪像比(SAR))来评估的。因此,所提出的方法比最小方差无失真响应(MVDR)波束形成器以及仅使用AF分析的方法提供更高的SDR、SAR、SIR和分离精度。

Short-Term Solar PV Forecasting Using Gated Recurrent Unit with a Cascade Model 基于串级模型的门控循环单元短期太阳能光伏预测
Nattawat Sodsong, Kun-Ming Yu, Ouyang Wen
The fluctuation in solar photovoltaic (PV) generation system causes inefficiency in PV power management. Thus, predicting solar PV power is essential to assist PV system in improving the overall performance of a solar plant operation. In this paper, solar PV forecasting model with multiple Gated Recurrent Unit (GRU) networks is proposed to effectively improve the prediction accuracy and the training time compared to the typical GRU network. In addition, other popular prediction machine learning algorithms, namely Feed-forward Artificial Neural Network (ANN), Support Vector Regression (SVR) and K Nearest Neighbors (KNN), were implemented for comparison with the proposed model. Each model was evaluated with Normalized Root Mean Squared Error (NRMSE). The proposed model, GRU, Feed-forward ANN, SVR, and KNN has NRMSE of 9.64%, 10.53%, 11.62%, 11.45%, and 11.89%, respectively. Hence, the proposed model provides enhanced prediction accuracy with improved speed compared with a GRU network.

Each model was evaluated with Normalized Root Mean Squared Error (NRMSE). The proposed model, GRU, Feed-forward ANN, SVR, and KNN has NRMSE of 9.64%, 10.53%, 11.62%, 11.45%, and 11.89%, respectively. Hence, the proposed model provides enhanced prediction accuracy with improved speed compared with a GRU network.","PeriodicalId":273383,"journal":{"name":"2019 International Conference on Artificial Intelligence in Information and Communication (ICAIIC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125425836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Performance Enhancement of Deep Neural Network Using Feature Selection and Preprocessing for Intrusion Detection 基于特征选择和预处理的深度神经网络入侵检测性能增强
Junghoon Woo, Joo-Yeop Song, Young-June Choi
Machine learning enables intrusion detection systems to detect network attacks adaptively and intelligently. Recently deep neural network has been investigated as such a solution owing to its high accuracy but it has limitation in real-time performance. To enhance the learning time, in this paper, we propose to use feature selection and layer configuration. We use the NSL-KDD data set, which is a refined version of the KDD CUP 99 data set and analyzed the associations between features using WEKA, a data mining tool. Our experimental results confirm that proper feature selection and layer configuration can reduce learning time while maintaining high average accuracy.
机器学习使入侵检测系统能够自适应地、智能地检测网络攻击。近年来,深度神经网络因其精度高而被研究作为一种解决方案,但在实时性方面存在局限性。为了提高学习时间,在本文中,我们提出使用特征选择和层配置。我们使用NSL-KDD数据集,这是KDD CUP 99数据集的改进版本,并使用数据挖掘工具WEKA分析了特征之间的关联。实验结果表明,适当的特征选择和层配置可以减少学习时间,同时保持较高的平均准确率。
