Pattern classification in domains that follow dissimilar distribution and where target domain has insufficient labelled samples, requires transfer of knowledge across domains through a process called domain adaption. Deep learning research demonstrates the transferability of deep convolutional features that are activations of intermediate layers of convolutional neural networks for domain adaption. Traditional clustering based domain adaption approaches are practical to handle knowledge transfer scenario. This paper presents a scheme that uses local neighborhoods based consistency analysis of one supervised and another unsupervised model to effectively transfer knowledge using deep features. Contrasting conventional models this approach uses only two models to classify patterns except hard ones. Neighbourhood consistency analysis identifies the hard samples, and is classified using a third model. Experimental analysis has been carried out focusing change on category variation of different samples for train and test cases. The proposed approach yields encouraging experimental result on benchmark domain adaption dataset compared to a deep feature based single support vector machine classifier in terms of state of the art metrics demonstrating effective generalization of source domain information.
在遵循不相似分布的领域和目标领域没有足够的标记样本时,模式分类需要通过称为领域适应的过程跨领域传递知识。深度学习研究证明了深度卷积特征的可转移性,这些特征是卷积神经网络用于域适应的中间层的激活。传统的基于聚类的领域自适应方法在处理知识转移场景时是可行的。本文提出了一种基于局部邻域的有监督模型和无监督模型的一致性分析方案,利用深度特征有效地转移知识。与传统模型相比,这种方法只使用两个模型来对模式进行分类,除了硬模型。邻域一致性分析识别硬样本,并使用第三种模型进行分类。针对训练用例和测试用例的不同样本类别变化进行了实验分析。与基于深度特征的单支持向量机分类器相比,该方法在基准域自适应数据集上取得了令人鼓舞的实验结果,证明了源域信息的有效泛化。

In the neoteric years, Graphene is one of the predominant resplendence in the horizon of fabrication technology owing to some of its tremendous electronic properties like zero band gap, high saturation velocity, higher electrical conductivity and so on. Graphene based devices are now being deliberated as one of possible options for post Si based electronics era. In this paper, we have analyzed the miscellaneous idiosyncratics of top gated graphene metal oxide semiconductor field effect transistor (MOSFET). Surface potential dependent quantum capacitance is obtained self-consistently along with linear and square root approximation. Gate voltage dependence of surface potential has been shown. Output characteristics, transfer characteristics of the proposed device model have been investigated. Considering all of the graphical illustrations, we strongly recommend Graphene to be a fellow replacement of silicon based devices in future MOSFET applications.

In recent years, silicon photonics has attracted attention as an emerging technology for optical telecommunications and for optical interconnects in microelectronics. The refractive index contrast plays a fundamental role in determining the characteristics of an optical dielectric waveguide and a higher index contrast permits to move towards larger scales of integration and to access new devices and functionalities. But high contrast waveguides are more difficult to realize and more critical but there are no serious impediments in their use. The aim of this contribution is to investigate the dependence of the waveguide characteristics with respect to the index contrast and explore the difficulties. In this paper, the impact of the index contrast on the characteristics of dielectric waveguides such as single mode regime, losses, fiber to waveguide coupling, technological constraints and available materials are investigated. The investigation shows that the dependence of the sensitivity in optical waveguide sensors on the polarization of guided modes is less in small refractive index difference waveguide compare than the silicon on silica waveguides but it provide flexibility to the design engineers.
近年来,硅光子学作为一种新兴的光通信技术和微电子领域的光互连技术受到了广泛的关注。折射率对比在决定光介质波导的特性中起着基本的作用,较高的折射率对比允许向更大的集成规模移动,并获得新的设备和功能。但高对比度波导的实现难度更大,也更关键,但在使用上没有严重的障碍。本贡献的目的是研究波导特性对折射率对比度的依赖关系,并探讨困难。本文研究了折射率对比对介质波导单模态、损耗、光纤与波导耦合、技术限制和可用材料等特性的影响。研究表明,在小折射率差波导中,光波导传感器的灵敏度对导模偏振的依赖性比硅上硅小,但它为设计工程师提供了灵活性。

Traditional way of learning programming is often tedious and fearsome to students, especially to kids. In most cases this results reluctance and uptake, while programming is the core of modern technology. Game is the signature of immersion. With its intense power of engaging players, it can wipe out the aversion and motivate students on coding. Here we have described a better way of learning programming with digital game. We have developed a cross platform game that provides a role playing game design for the player, at the same time a kinesthetic approach to reinforce the basic concepts of programming.

Automatic bug assignment is an essential activity aiming at assigning bugs to appropriate developers. Existing approaches consider either recent commits or previous bug fixes of developers, leading to recommendation of inexperienced or inactive developers respectively. Considering only one information source leads these approaches to low prediction accuracy. An approach called ERBA is proposed, which considers both expertise and recent activities of developers. ERBA first processes source code and commit logs to construct an index connecting the source entities with developer recent activities. Next, it takes fixed bug reports and builds another index, mapping the bug report keywords with developer bug fixing expertise. On arrival of new bug reports, the final module queries the two indexes using the new bug report terms, and applies tf-idf technique on the query result to calculate an ERBA score for developers. Finally, an ascending ordered list on ERBA score is suggested. For assessment of competency, a case study has been conducted on Eclipse JDT. It depicts that ERBA outperforms existing approach by improving prediction accuracy from 33.8% upto 44%. The result also represents that ERBA shows the first correct developer on average near 4.04 ranks, whereas existing approach shows in 7.27.
自动错误分配是一项重要的活动,旨在将错误分配给适当的开发人员。现有的方法要么考虑开发人员最近的提交,要么考虑以前的错误修复,从而分别推荐缺乏经验的开发人员或不活跃的开发人员。仅考虑一个信息源导致这些方法的预测精度较低。提出了一种称为ERBA的方法,它考虑了开发人员的专业知识和最近的活动。ERBA首先处理源代码和提交日志,以构造一个索引,将源实体与开发人员最近的活动连接起来。接下来,它获取修复的bug报告并构建另一个索引,将bug报告关键字与开发人员修复bug的专业知识进行映射。在收到新的bug报告时,最后一个模块使用新的bug报告术语查询这两个索引,并对查询结果应用tf-idf技术,为开发人员计算ERBA分数。最后,提出了ERBA分数的升序排序方法。为了评估能力,对Eclipse JDT进行了一个案例研究。它描述了ERBA通过将预测精度从33.8%提高到44%而优于现有方法。结果还表明,ERBA显示第一个正确的开发人员的平均排名接近4.04,而现有方法显示的排名为7.27。

Financial services through the internet are running under various threats like phishing, pharming (cyber attack intended to redirect a website's traffic to another fake site), malware, and evolving sophistication of compromise techniques. Multi-factor authentication (MFA) financial service system alleviates the risk and makes it secure. Various methods of MFA run in troubles like the authentication device lost or stolen, false sense of security (if used on login device), compromised answer of the generic question, higher implementation costs, unambiguous movement profile, calculated hash value stolen (there is no chance to replace it), etc. Compliance with Anti-Money Laundering (AML), Know Your Customer (KYC) and sanction requirements continue to be a key focus area for Financial Institutions' (FIs) management; firms must ensure that they are following appropriate compliance procedures to meet the increasing regulatory demands [1,2]. By addressing existing limitation of MFA, this paper proposes dynamic KYC based MFA authentication method to ensure the secured access of the financial services through the internet. Analysis and simulation results show that the proposed method provides control same as existing MFA/2FA techniques, but customers will get relief from holding additional security devices that incur huge cost.
互联网上的金融服务面临着各种各样的威胁,比如网络钓鱼、网络欺诈(旨在将一个网站的流量重定向到另一个虚假网站的网络攻击)、恶意软件和不断发展的复杂的折衷技术。多因素认证(MFA)金融服务系统降低了风险,提高了安全性。MFA的各种方法在运行时会遇到麻烦,比如身份验证设备丢失或被盗、错误的安全感(如果在登录设备上使用)、通用问题的答案泄露、更高的实现成本、明确的移动配置文件、计算的哈希值被盗(没有机会替换它)等。遵守反洗钱(AML)、了解客户(KYC)和制裁要求仍然是金融机构(fi)管理的重点领域;公司必须确保他们遵循适当的合规程序,以满足日益增长的监管要求[1,2]。针对MFA存在的局限性,提出了一种基于动态KYC的MFA认证方法,以保证金融服务通过互联网的安全访问。分析和仿真结果表明,该方法提供了与现有MFA/2FA技术相同的控制,但客户将不必持有额外的安全设备,从而产生巨大的成本。

The sentiment of a sentence or a comment can be detected more accurately by applying Word Embeddings. This article presents the idea of word co-occurrence matrix and Skip-Gram to determine the actual contexts of the words, Hellinger PCA to determine the most similar words and generate a sliding window of most probable context words around each word. It is shown that, by applying Word Embeddings to classify the sentiment of a comment achieves higher accuracy with larger corpus. For our corpus of 2500 comments, the accuracy achieved is 70%, which is rapidly increasing with the size of the corpus.

Success of any supply chain highly depends on the appropriate use of transportation. It is always a tough decision to select an optimal route in the stages of a supply chain that will balance the reverse condition of cost and time. Q-learning is already getting implied to optimize routes, but it greatly lacks in designing a complete Markov Decision Process (MDP) with enough number of states and actions sets. In this paper, we propose an MDP that can fit the design of a proper multi-stage supply chain network and intend to solve the MDP with SARSA (X) algorithm. The algorithm was simulated in a java based environment and experimental results show that Q-learning produced higher chunks of rewards but SARSA (X) was faster in case of convergence speed.
任何供应链的成功在很大程度上取决于运输的适当使用。在供应链的各个阶段中选择一条最优路线,以平衡成本和时间的反向条件,一直是一个艰难的决定。Q-learning已经被用于优化路径,但它在设计一个具有足够数量的状态和动作集的完整马尔可夫决策过程(MDP)方面非常缺乏。在本文中,我们提出了一个适合多阶段供应链网络设计的MDP,并打算用SARSA (X)算法求解MDP。在java环境下对该算法进行了仿真,实验结果表明,Q-learning产生的奖励块更高,而SARSA (X)在收敛速度方面更快。

Change detection from remote sensing images is getting more interest now a days because of abrupt changes in earth surface due to natural disasters or man-made activities. So it's an important research question of how to extract relevant information about the changes due to rainfall, droughts, flooding, destroying land cover areas and so on. This problem has been studied in some research however many of these did not consider the nonlinear relationship while detecting the changes. In this research, above limitation has been addressed and Weighted Normalized Mutual Information (WNMI) is utilized for the improvement. The WNMI technique has been applied between the reference and target images to find out the changes. Thus the changes between every object of the given dataset have been identified and able to observe the damage of any specific area as well as its subsequent recovery. Weighting has been done to count significance at the pixel level. The proposed technique can detect the changes more effectively than the traditional mutual information approach. Experimental analysis is carried on real remote sensing images and it is found that the proposed method can detect more than 96% of changes which is much better than the standard benchmark techniques.
由于自然灾害或人为活动引起的地球表面突变,遥感图像的变化检测越来越受到人们的关注。因此,如何提取降雨、干旱、洪水、破坏土地覆盖面积等变化的相关信息是一个重要的研究问题。虽然已有一些研究对这一问题进行了研究,但许多研究在检测变化时没有考虑非线性关系。本研究针对上述局限性,利用加权归一化互信息(WNMI)进行改进。在参考图像和目标图像之间应用WNMI技术来发现图像的变化。因此,已经确定了给定数据集的每个对象之间的变化,并能够观察任何特定区域的损害及其随后的恢复。加权是为了在像素水平上计算显著性。该方法可以比传统的互信息方法更有效地检测到变化。在真实遥感图像上进行了实验分析,结果表明,该方法能检测出96%以上的变化,大大优于标准基准技术。
