Identifying digital investing services using design thinking methodology 使用设计思维方法识别数字投资服务
P. Fehér, Krisztián Varga
Incumbent financial institutions are continuously challenged by small fintech startups and big technology enterprises in finding ways to offer new, customer centric, and most importantly digital services. This paper is focusing on the investing services. The presented research is using Design Thinking methodology to identify challenges of investing activities and finding digital ways to answer these challenges. Our target customer group were those, who are not investing right now, as we wanted to identify what are their barriers of entering the investment market. The research sample focuses on educated, young generations. Although the financial background of the sample provides a good opportunity of investments, alternate use of savings is more widespread, and the general behavior of the analyzed generation requires liquid assets. The qualitative answers highlight the necessity of knowledge, trust and external expertise for investing decisions. The research generated four main possible products for the non-investing segment in order to gain their trust, educate them or to offer them an opportunity that does not need huge amount of money in investment.
现有的金融机构不断受到小型金融科技初创公司和大型科技企业的挑战,他们要想办法提供新的、以客户为中心的、最重要的是数字服务。本文的研究重点是投资服务。目前的研究使用设计思维方法来识别投资活动的挑战,并找到应对这些挑战的数字化方法。我们的目标客户群是那些现在没有投资的人,因为我们想要确定他们进入投资市场的障碍是什么。研究样本集中在受过教育的年轻一代。虽然样本的金融背景提供了一个很好的投资机会,但储蓄的替代使用更为普遍,并且所分析的一代人的一般行为需要流动资产。定性回答强调了知识、信任和外部专业知识对投资决策的必要性。为了获得他们的信任,教育他们或为他们提供一个不需要大量投资的机会,研究为非投资部分产生了四种主要的可能产品。

Big Data with Decision Tree Induction 基于决策树归纳的大数据
Shabnam Sabah, Sara Anwar, Sadia Afroze, Md. Abulkalam Azad, Swakkhar Shatabda, D. Farid
Big data mining is one of the major challenging research issues in the field of machine learning for data mining applications in this present digital era. Big data consists of 3V’s: (1) volume - massive amount of data/too many bytes, (2) velocity - high speed streaming data/too high a rate, and (3) variety - data are coming from different sources/too many sources. Collecting and managing real-life big data is a difficult task, as big data is so big that we cannot keep all the data together in a single machine. Therefore, we need advanced relational database management systems with parallel computing to deal with big data. Knowledge mining from big data employing traditional machine learning and data mining techniques is a big issue and attract computational intelligent researcher in this area. In this paper, we have used the decision tree (DT) induction method for mining big data. Decision tree induction is one of the most preferable and well-known supervised learning technique, which is a top-down recursive divide and conquer algorithm and require little prior knowledge for constructing a classifier. The traditional DT algorithms like Iterative Dichotomiser 3 (ID3), C4.5 (a successor of ID3 algorithm), Classification and Regression Trees (CART) are generally built for mining relatively small datasets. So, we need a more scalable decision tree learning approach for mining big data. In this paper, we have engendered several trees employing two scalable decision tree algorithms: RainForest Tree and Bootstrapped Optimistic Algorithm for Tree construction (BOAT) using seven benchmark datasets from Keel Repository and UCI Machine Learning repository. We have compared the performance of RainForest and BOAT algorithms. Also, we have proposed a decision tree merging approach, as decision tree merging is a very complex and challenging task.
大数据挖掘是当前数字时代数据挖掘应用中机器学习领域的主要挑战性研究问题之一。大数据由3V组成:(1)体积——海量数据/太多字节,(2)速度——高速数据流/速率太高,(3)多样性——数据来自不同的来源/太多的来源。收集和管理现实生活中的大数据是一项艰巨的任务,因为大数据非常大,我们无法将所有数据保存在一台机器中。因此,我们需要先进的并行计算关系数据库管理系统来处理大数据。利用传统的机器学习和数据挖掘技术从大数据中挖掘知识是一个大问题,吸引了计算智能研究者的关注。在本文中,我们使用决策树(DT)归纳法对大数据进行挖掘。决策树归纳法是一种自顶向下递归的分而治之算法,构造分类器需要很少的先验知识,是最受欢迎和最知名的监督学习技术之一。传统的DT算法,如迭代二分器3 (ID3), C4.5 (ID3算法的后继算法),分类和回归树(CART)通常是为挖掘相对较小的数据集而构建的。因此,我们需要一种更具可扩展性的决策树学习方法来挖掘大数据。在本文中,我们使用来自龙骨存储库和UCI机器学习存储库的七个基准数据集,使用两种可扩展的决策树算法生成了几棵树:雨林树和bootstrap乐观树构建算法(BOAT)。我们比较了RainForest和BOAT算法的性能。此外,由于决策树合并是一个非常复杂和具有挑战性的任务,我们提出了一种决策树合并方法。

The Computer Nose Best 电脑鼻子最好
S. Jilani, H. Ugail, Andrew Logan
The nose is the most central feature on the face which is known to exhibit both gender and ethnic differences. It is a robust feature, invariant to expression and known to contain depth information. In this paper we address the topic of binary ethnicity classificiation from images of the nose, using a novel dataset of South Asian, Pakistani images. To the best of our knowledge, we are one of the first to attempt demographic (ethnicity) based identification based solely on information from the nose.A two-category (Pakistani vs Non-Pakistani) task was used in combination with Deep learning (ResNet) based and VGG-based pre-trained models. A series of experiments were conducted using ResNet-50, ResNet-101, ResNet-152, VGG-Face, VGG-16 and VGG-19, for feature extraction and a Linear Support Vector Machine for classification. The experimental results demonstrate ResNet-50 achieves the highest performance accuracy of 94.1%. In comparison, the highest score for the VGG-based models (VGG-16) was 90.8%. These results demonstrate that information from the nose is sufficient for deep learning models to achieve >90% accuracy on judgements of ethnicity.
鼻子是面部最重要的特征,它显示出性别和种族的差异。它是一个鲁棒特征,表达式不变,已知包含深度信息。在本文中,我们使用一个新的南亚、巴基斯坦图像数据集,从鼻子图像中解决了二元种族分类的主题。据我们所知,我们是第一个尝试仅根据鼻子信息进行人口统计(种族)识别的人。两类(巴基斯坦vs非巴基斯坦)任务与基于深度学习(ResNet)和基于vgg的预训练模型结合使用。采用ResNet-50、ResNet-101、ResNet-152、VGG-Face、VGG-16和VGG-19进行特征提取和线性支持向量机进行分类。实验结果表明,ResNet-50达到了94.1%的最高性能准确率。而基于vgg的模型(VGG-16)得分最高,为90.8%。这些结果表明,来自鼻子的信息足以让深度学习模型在种族判断上达到>90%的准确率。

Ehtzaz Chaudhry, A. Noreika, L. You, Jian-Jun Zhang, Jian Chang, H. Ugail, Alexander Malyshev, A. Carriazo, A. Iglesias, Z. Habib, Allah Bux Sargano, H. Haron
This paper presents a partial differential equation (PDE)-based surface modelling and simulation framework for lily flowers. We use a PDE-based surface modelling technique to represent shape of a lily flower and PDE-based dynamic simulation to animate blossom and decay processes of lily flowers. To this aim, we first automatically construct the geometry of lily flowers from photos to obtain feature curves. Second, we apply a PDE-based surface modelling technique to generate sweeping surfaces to obtain geometric models of the flowers. Then, we use a physics-driven and data-based method and introduce the flower shapes at the initial and final positions into our proposed dynamic deformation model to generate a realistic deformation of flower blossom and decay. The results demonstrate that our proposed technique can create realistic flower models and their movements and shape changes against time efficiently with a small data size.
提出了一种基于偏微分方程(PDE)的百合表面建模与仿真框架。我们使用基于pde的表面建模技术来表示百合花的形状,并使用基于pde的动态仿真来动画百合花的开花和腐烂过程。为此,首先从照片中自动构造百合花朵的几何形状,得到特征曲线。其次,我们应用基于pde的表面建模技术来生成扫描表面,以获得花朵的几何模型。然后,我们使用物理驱动和基于数据的方法,将花在初始和最终位置的形状引入到我们提出的动态变形模型中,以生成真实的花开花和腐烂变形。结果表明,该技术可以在较小的数据量下高效地生成真实的花卉模型及其运动和形状随时间的变化。

Real-Time Video Dehazing for Industrial Image Processing 用于工业图像处理的实时视频去雾
Hayat Ullah, I. Mehmood
In today’s industries, automation, reliability, robustness and accuracy are pivotal problem to cut costs and increase productivity and quality. Visual sensor networks are vital control and monitoring tools for continues, on-line imaging and real time image processing in production and plant process. Most of the industrial videos are captured in hazy weather and usually degraded by suspended particles of atmosphere, such as smoke, fog, rain, and snow, which limits the visual quality of image. This hinders the ability of artificial intelligent driven systems to achieve automation, reliability and accuracy. Recovery of the clear visuals from the input hazy videos is challenging problem. Instead of relying on explicitly estimating the key component of atmospheric scattering model, we present end-to-end CNN model, which directly recovers the clear images from hazy images. This end-to-end architecture makes it an ideal pre-processing tool into other deep models for increasing the efficiency of various computer vision tasks in real time systems, such as Retina-Net for object detection, ResNet for object recognition. Experimental results demonstrate the effectiveness and robustness of proposed framework by outperforming the stat-of-the-art approaches in terms of time complexity and visual quality.
在当今的工业中,自动化、可靠性、稳健性和准确性是降低成本、提高生产率和质量的关键问题。视觉传感器网络是生产和工厂过程中连续、在线成像和实时图像处理的重要控制和监测工具。大多数工业视频都是在雾蒙蒙的天气中拍摄的,通常会被大气中的悬浮颗粒(如烟、雾、雨、雪)降解,从而限制了图像的视觉质量。这阻碍了人工智能驱动系统实现自动化、可靠性和准确性的能力。从输入的模糊视频中恢复清晰的视觉效果是一个具有挑战性的问题。本文提出了端到端CNN模型,该模型不依赖于对大气散射模型关键分量的显式估计,而是直接从朦胧图像中恢复清晰图像。这种端到端架构使其成为其他深度模型的理想预处理工具,用于提高实时系统中各种计算机视觉任务的效率,例如用于对象检测的Retina-Net,用于对象识别的ResNet。实验结果表明,该框架在时间复杂度和视觉质量方面优于现有的方法,具有良好的鲁棒性和有效性。

Evolutionary Behavioral Design of Non-Player Characters in a FPS Video Game Through Particle Swarm Optimization 基于粒子群优化的FPS电子游戏非玩家角色进化行为设计
Guillermo Díaz, A. Iglesias
Evolutionary computation covers the family of artificial intelligence techniques inspired by nature and biological evolution. These methods, such as swarm intelligence, may have a very positive impact on video games, for instance, for the design of Non-Player Characters (NPCs) to obtain a realistic intelligent behavior in a simple way. To this aim, we describe an evolutionary behavioral design of NPCs using particle swarm optimization in a first-person shooter video game. Several computer experiments have been carried out to analyze the feasibility and performance of this approach. Our experimental results show that the proposed method performs very well and can be successfully used in a fully automatic (i.e., without any human player) and efficient way.

Novel Technique for Isolated Sign Language Based on Fingerspelling Recognition 基于指纹拼写识别的孤立手语新技术
Ahmad Yahya Dawod, N. Chakpitak
Sign language is used by deaf and hard hearing people to exchange information between their own community and with other people. Fingerspelling recognition method from isolate sign language has attracted research interest in computer vision and human-computer interaction based on a novel technique. The essential for real-time recognition of isolate sign language has grown with the emergence of better-capturing devices such as Kinect sensors. The purpose of this paper is to design a user independent framework for automatic recognition of American Sign Language which can recognize several one-handed dynamic isolated signs and interpreting their meaning. We built datasets as a raw data for alphabets (A–Z) or numbers (1–20) by used left-hand the 3D point (XL, YL, ZL) or switch by right-hand (XR, YR, ZR) centroid as one of contribution. The proposed approach was tested for gestures that involve left-hand or right-hand and was compared with other approach and gave better accuracy. Two machine learning methods are involved like Hidden Conditional Random Field (HCRF), and Random Decision Forest (RDF) for the classification part. The third contribution based on low lighting condition and cluttered background. In this research work is achieved for recognition accuracy over 99.7%.
手语是聋哑人和重听人用来在自己的社区和与其他人之间交换信息的语言。孤立手势语的手势语拼写识别方法作为一种新颖的技术,在计算机视觉和人机交互领域引起了广泛的研究兴趣。随着诸如Kinect传感器等更好捕捉设备的出现,对孤立的手语进行实时识别的必要性也在增加。本文的目的是设计一个独立于用户的美国手语自动识别框架,该框架可以识别多个单手动态孤立手势并解释其含义。我们将数据集作为字母(a - z)或数字(1-20)的原始数据,使用左手3D点(XL, YL, ZL)或右手切换(XR, YR, ZR)质心作为贡献之一。该方法在涉及左手或右手的手势上进行了测试,并与其他方法进行了比较,结果准确率更高。分类部分涉及到隐藏条件随机场(HCRF)和随机决策森林(RDF)两种机器学习方法。第三个贡献是基于低光照条件和杂乱的背景。在本研究工作中,识别准确率达到99.7%以上。

Remodeling Hospitality Industry through Artificial Intelligence 通过人工智能重塑酒店业
A. Imad
Remodeling the hospitality industry through artificial intelligence (AI) – that uses big data analytics and complex machine learning – is a concept that will help the industry to leapfrog to the next level. The notion put forward in this paper is to develop a framework to utilize machine learning analyses the multi-channel user data for efficient decision making to enrich the customer experience and to provide the maximum revenue to the vendor. We propose strategies to infer customer behaviors by capturing otherwise salient information – e.g. through the various digital footprints. Feeding such analytics to a suitably trained collection of machine learning algorithms called the “Digital Operations Manager” helps to automate complex decision making, removing human error and bias. The proposed AI system, if appropriately deployed within a hospitality industry environment, is thought to bring out a significant gain in the user choice and experience as well as efficiency in resource management and revenue optimization.
通过使用大数据分析和复杂机器学习的人工智能(AI)重塑酒店业,这一概念将帮助酒店业跨越式发展。本文提出的概念是开发一个框架,利用机器学习分析多渠道用户数据进行有效的决策,以丰富客户体验并为供应商提供最大的收入。我们提出了通过捕捉其他显著信息(例如通过各种数字足迹)来推断客户行为的策略。将这些分析提供给经过适当训练的机器学习算法集合,称为“数字运营经理”,有助于自动化复杂的决策,消除人为错误和偏见。拟议的人工智能系统,如果在酒店行业环境中适当部署,被认为可以在用户选择和体验以及资源管理效率和收入优化方面带来显着收益。
