Tor匿名通信流量在线识别方法

匿名通信技术的滥用给网络监管带来了新的挑战.有效识别出匿名通信流量,是阻止该类技术滥用的前提,具有重要的研究意义和应用价值.现有研究工作侧重于匿名通信关系的确认,无法用于匿名通信流量的识别和阻塞.针对这个问题,围绕广泛使用的Tor匿名通信系统,深入分析运行机制,归纳总结其流量特征.在此基础上,分别提出基于TLS指纹和基于报文长度分布的Tor匿名通信流量识别方法.对两种识别方法的优缺点和适用性进行了详细分析和讨论,并通过CAIDA数据集和在线部署对识别方法进行了验证.实验结果表明,基于TLS指纹和基于报文长度分布的识别方法均能有效识别出Tor匿名通信流量.

Adaptive Estimation of Fuzzy Cognitive Maps With Proven Stability and Parameter Convergence

Fuzzy cognitive maps (FCMs) have been introduced by Kosko to model complex behavioral systems in various scientific areas. One issue that has not been adequately studied so far is the conditions under which they reach a certain equilibrium point after an initial perturbation. This is equivalent to studying the existence and uniqueness of solutions for their concept values. In this paper, we study the existence of solutions of FCMs equipped with continuous differentiable sigmoid functions having contractive or, at least, nonexpansive properties. This is done by using an appropriately defined contraction mapping theorem and the nonexpansive mapping theorem. It is proved that when the weight interconnections fulfill certain conditions, the concept values will converge to a unique solution, regardless of the exact values of the initial concept values perturbations, or in some cases, a solution exists that may not necessarily be unique; otherwise, the existence or the uniqueness of equilibrium cannot be assured. Based on these results, an adaptive weight-estimation algorithm is proposed that employs appropriate weight projection criteria to assure that the uniqueness of FCM solution is not compromised. In view of these results, recently proposed extensions of FCM, which are the fuzzy cognitive networks (FCN), are invoked.

Adaptive WTA With an Analog VLSI Neuromorphic Learning Chip

In this paper, we demonstrate how a particular spike-based learning rule (where exact temporal relations between input and output spikes of a spiking model neuron determine the changes of the synaptic weights) can be tuned to express rate-based classical Hebbian learning behavior (where the average input and output spike rates are sufficient to describe the synaptic changes). This shift in behavior is controlled by the input statistic and by a single time constant. The learning rule has been implemented in a neuromorphic very large scale integration (VLSI) chip as part of a neurally inspired spike signal image processing system. The latter is the result of the European Union research project Convolution AER Vision Architecture for Real-Time (CAVIAR). Since it is implemented as a spike-based learning rule (which is most convenient in the overall spike-based system), even if it is tuned to show rate behavior, no explicit long term average signals are computed on the chip. We show the rule's rate-based Hebbian learning ability in a classification task in both simulation and chip experiment, first with artificial stimuli and then with sensor input from the CAVIAR system

Different Styles for Different Needs – The Effect of Cognitive Styles on Idea Generation

Researchers are engaged in finding the precursors for innovation. Drawing on Kirton's Adaption‐Innovation (KAI) Inventory, we explicitly test Kirton's central premise that cognitive styles differentiate between preferences for producing ideas in a certain way. We argue that the generation of either a magnitude or original ideas is governed by different underlying cognitive styles. In a study with 191 individuals, we find that the cognitive style originality associates with ideational fluency whereas the rule governance style associates with the generation of original ideas. By providing a cognitive explanation for how ideas are generated, we deepen the understanding of the idea generation process. This is particularly important for the future use of the KAI and for organizations that strive to be innovative.

基于自适应遗传神经网络的银行客户分类研究

银行产品的营销行为都是针对广大客户的。若能提前分辨出哪些是优质客户,再为其定制合理的营销策略,那银行就能获得更大的竞争力。文中将遗传算法与BP神经网络结合用于对银行客户分类进而预测客户是否会购买银行产品。该方法有效地克服了BP神经网络容易陷入局部极小值和收敛速度慢的问题,并且针对其中遗传算法的计算时间和精度问题提出了一种新的自适应遗传算法。实验结果表明,基于这种自适应的遗传神经网络的方法用更短的计算时间达到了更高的预测精度,可以准确地为银行客户分类。

Online Ideology: A Comparison of Website Communication and Media Use

This study examined and compared the websites of ideological groups from a communications and media use perspective. Thirty‐six websites with message boards categorized as either violent ideological, nonviolent ideological, or nonviolent nonideological were content coded for several distinguishing characteristics. The results indicated that group type was predicted by the type of information presented, the difficulty of becoming a member, and the amount of freedom members had on discussion boards. These findings suggest that characteristics of violent ideological group websites can be used to distinguish them from websites of both nonviolent ideological and nonideological groups. This study also provides a demonstration of a research methodology that can be used to naturally observe ideological groups via an online setting.     

The Effect of Information Design on Cognitive Processing of Website Navigation

The information displayed on a website is a critical factor that affects the cognition of internet users. This study adopted a between‐subjects design to examine the effect of the information design of a website and the involvement of internet users on purchasing cognition. The results indicated significant differences between high‐ and low‐quality diagnostic information on the purchasing cognition of subjects. The subjects had better purchasing cognition when navigating a high‐quality diagnostic information website than when navigating a low‐quality diagnostic information website. In addition, there was a significant interactive effect of different qualities of nondiagnostic information and subject involvement on purchasing cognition. Namely, the subjects who had low involvement had better purchasing cognition when navigating a website with high‐quality nondiagnostic information than when browsing one with low‐quality nondiagnostic information, but there was no significant difference between navigating websites with high‐ and low‐quality nondiagnostic information if the subjects had high involvement.
