In this paper, the problem of adaptive controller for Lorenz system with unknown parameters is studied. Based on Lyapunov theory, the novel adaptive controller with logic-based switching mechanism is established. In the process of design, all uncertain parameters are estimated centralized via logic-based switching mechanism to avoid the deterioration of the system performance caused by the successive estimates of several unknown parameters. The novel design can improve the dynamic performance of the system and increase the robustness of the system. Lyapunov theorem and Barbalat lemma demonstrate global asymptotic stability of chaotic controlled system. The simulation results show feasibility and effectiveness of the method.

Intelligent robots or autonomous agents that could express human-like emotions are more trustworthy when humans communicate with them. Agents choose appropriate actions not only depending on current goals and the information perceived from the environment, but also on their mental state. We take formal accounts of how to represent affective states of agents when reasoning about actions and their effects. We discuss the computational description by mapping our model onto the Bayesian networks. In this paper, we propose a logical approach that clearly illustrates the relations among actions, situations, sensing, and affective states in the situation calculus.

With the development of the Internet of things(IoT), many various IoT applications continue to emerge. How to evaluate the approbate degree of users on IoT applications is an important problem in IoT research. To address this problem, this paper presents an IoT quality of experience(QoE) evaluation method based on multiple linear regression analysis. Firstly, this paper analyzes the type of IoT applications, determines the quality of service(QoS) parameters of QoE and collects the sample data. Then, it gets the principal components by principal component analysis, associates QoE to the principal components based on multiple regression analysis and builds the regression equation between QoE and principal components. Finally, it gets the functional model between QoE and QoS parameters on the basis of the regression equation. Experimental results show that this evaluation method can reduce the complexity of QoE evaluation and quantify functional relation between QoE and QoS parameters.
随着物联网的发展，各种各样的物联网应用不断涌现。如何评价用户对物联网应用的认可程度是物联网研究中的一个重要问题。针对这一问题，本文提出了一种基于多元线性回归分析的物联网体验质量(QoE)评价方法。首先，分析物联网应用类型，确定QoS (quality of service，服务质量)参数，采集样本数据。然后通过主成分分析得到主成分，通过多元回归分析将QoE与主成分关联起来，建立了QoE与主成分之间的回归方程。最后，在回归方程的基础上，得到了QoS质量质量与QoS参数之间的函数模型。实验结果表明，该评价方法降低了QoE评价的复杂性，量化了QoE与QoS参数之间的函数关系。

This paper presents an anti-interference method of massive multi-input multi-output (Massive MIMO) based on antenna selection. Assume that both the base station (BS) and mobile station (MS) can acquire real-time channel state information (CSI), the transmitter and receiver select a set of antennas to transmit signals according to the optimization criterion of maximum channel capacity using an improved distributed antenna selection algorithm with low complexity. After antenna selection, the interference from different spatial data flow is then aligned in one direction or into one subspace, leaving most of the spatial degrees of freedom for useful signals. Simulation results show that the proposed scheme achieves considerably better performance than the zero-forcing (ZF) precoding solution, this advantage is especially obvious in a high SNR regime.

Wireless Sensors Networks (WSNs) are susceptible to many security threats, and because of communication, computation and delay constraints, traditional security mechanisms cannot be used. When trust system is established, the route from source node to destination node should consider nodes' trust on the road but not only QoS. In this paper, we propose a routing model in trust WSNs with respect to both trust and delay. Comparing with ECCR, our model is more accurate in data and reliable in transmission.

This paper describes our work for ALIDATA DISCOVERY competition. Through analyzing massive real-world user action data provided by Tmall, one of the largest B2C online retail platforms in China, we try to predict future user purchases. The prediction results are judged by F1 Score that is consist of two parts, precision and recall rate. The provided data set contains more than 500 million action records from over 12 million distinct users. Such a massive data set drives us to finish the task in MapReduce fashion on the Open Data Processing Service (ODPS) platform. According to statistical results, we classify all users into different groups firstly. Then the rule model, timing model, statistics model are adopted for predicting future user purchases. By comparison, the statistics model obtains the best F1Score.

Synonym ring is the most important method to do query expansion in information retrieval area. But most research on synonym ring remain on the algorithm level. This paper introduces a query assistant system based on academic synonym ring named “Academic Query Assistant” (AQA), which can be applied for other systems such as search engines. By the one and a half years of actual running, the results show that AQA can effectively help users to do query expansion.
