电子商务中基于深度学习的虚假交易识别研究     

刘畅  殷聪 《现代情报》2016,36(10):62

为了解决电子商务平台中存在的虚假交易问题,本文依据商品的销售记录以及商家的基本信息,提出了一种结合深度置信网络和多层感知器的虚假交易识别方法,通过识别出以通过刷单增加销量的商品来识别虚假交易。首先利用深度置信网络对交易特征进行学习,得到更高层次的抽象特征;然后利用多层感知器进行分类任务,从而识别出虚假交易。从淘宝中爬取商品的交易记录和评论数据进行实验验证,与其他机器学习模型的实验结果进行对比,其性能有明显的提升。  相似文献   

<Emphasis Type="Italic">Dis</Emphasis>closive Ethics and Information Technology: <Emphasis Type="Italic">Disclosing Facial Recognition Systems</Emphasis>     

Lucas?D.?IntronaEmail author 《Ethics and Information Technology》2005,7(2):75-86

This paper is an attempt to present disclosive ethics as a framework for computer and information ethics – in line with the suggestions by Brey, but also in quite a different manner. The potential of such an approach is demonstrated through a disclosive analysis of facial recognition systems. The paper argues that the politics of information technology is a particularly powerful politics since information technology is an opaque technology – i.e. relatively closed to scrutiny. It presents the design of technology as a process of closure in which design and use decisions become black-boxed and progressively enclosed in increasingly complex socio-technical networks. It further argues for a disclosive ethics that aims to disclose the nondisclosure of politics by claiming a place for ethics in every actual operation of power – as manifested in actual design and use decisions and practices. It also proposes that disclosive ethics would aim to trace and disclose the intentional and emerging enclosure of politics from the very minute technical detail through to social practices and complex social-technical networks. The paper then proceeds to do a disclosive analysis of facial recognition systems. This analysis discloses that seemingly trivial biases in recognition rates of FRSs can emerge as very significant political acts when these systems become used in practice.

我党对商品经济和市场经济的认识,一直是放在与社会主义的相互关系中来把握的。按照对其认识的进程划分,主要经历了三个阶段:即对立阶段、统一阶段和确认市场经济是社会主义经济体制的阶段。这一认识进程表明,我党是一个善于把马克思主义的基本原理与中国具体建设实际相结合、不断接受实践检验、不断总结实践经验的政党,是一个勇于理论创新、坚持与时俱进的政党。  相似文献   

Emotion recognition in fathers and mothers at high-risk for child physical abuse     

Asla N  de Paúl J  Pérez-Albéniz A 《Child abuse & neglect》2011,35(9):712-721

Objective

The present study was designed to determine whether parents at high risk for physical child abuse, in comparison with parents at low risk, show deficits in emotion recognition, as well as to examine the moderator effect of gender and stress on the relationship between risk for physical child abuse and emotion recognition.

Methods

Based on their scores on the Abuse Scale of the CAP Inventory (Milner, 1986), 64 parents at high risk (24 fathers and 40 mothers) and 80 parents at low risk (40 fathers and 40 mothers) for physical child abuse were selected. The Subtle Expression Training Tool/Micro Expression Training Tool ( [Ekman, 2004a] and [Ekman, 2004b]) and the Diagnostic Analysis of Nonverbal Accuracy II (Nowicki & Carton, 1993) were used to assess emotion recognition.

Results

As expected, parents at high risk, in contrast to parents at low risk, showed deficits in emotion recognition. However, differences between high- and low-risk participants were observed only for fathers, but not for mothers. Whereas fathers at high risk for physical child abuse made more errors than mothers at high risk, no differences between mothers at low risk and fathers at low risk were found. No interaction between stress, gender, and risk status was observed for errors in emotion recognition.

Conclusions and practice implications

The present findings, if confirmed with physical abusers, could be helpful to further our understanding of deficits in processing information of physically abusive parents and to develop treatment strategies specifically focused on emotion recognition. Moreover, if gender differences can be confirmed, the findings could be helpful to develop specific treatment programs for abusive fathers.  相似文献   

RPL for accreditation in higher education – As a process of mutual understanding or merely lifeworld colonisation?     

Fredrik Sandberg  Per Andersson 《Assessment & Evaluation in Higher Education》2011,36(7):767-780

This article focuses on a process of recognition of prior learning (RPL) in higher education. It is based on experiences from a project carried out in collaboration between the University of Lund, Linköping University and two trade unions in Sweden. The aim of the project was to find ways of recognising prior learning for accreditation of course credits at university level. In the project and its analysis, Habermas’ theory of communicative action was used as theoretical underpinning. During the project we carried out a thematic analysis based on interviews. The analysis suggested that the participants had a mystified view of higher education that RPL must be considered a learning process and that the participants’ prior learning can be characterised as practical wisdom. These themes guided the development of the project. In a retrospective analysis, language proficiency seemed to play a significant role for the outcome of the process. The conclusion suggests that a more fair and valid assessment of the participant’s prior learning could be accomplished by focusing on RPL as a process of mutual understanding. However, a critical appraisal of the process suggests that RPL for accreditation is problematic and could be seen as a colonisation of the lifeworld.  相似文献   

Performativity,well‐being,social class and citizenship in English schools     

Pamela Fisher 《Educational studies》2011,37(1):49-58

A range of initiatives to promote well‐being and empowerment have been introduced into English schools. These ostensibly support the citizenship curriculum that seeks to foster a more active and engaged populace. Whilst children are being encouraged to view their own well‐being as a personal project (and as a badge of successful citizenship), this process is being undermined by an informal curriculum of citizenship, embedded within the culture of performativity, that is promoting a climate of misrecognition within schools. This form of “symbolic violence” (that affects working‐class families disproportionately) is encroaching into the private sphere, traditionally a potential refuge providing opportunities for the development of forms of well‐being that were not dependent on institutional endorsement. It is suggested that some of the counter‐hegemonic values developed in the face of marginalisation might usefully inform issues of citizenship and well‐being in schools in ways that would encourage genuinely empowered forms of citizenship.  相似文献
