Deep neural networks are widely used in speech recognition and face verification with excellent performance, and they are gradually applied and developed in the field of customer credit scoring. Traditional credit scoring work relies on the two-step modeling process of feature processing and model building, which cannot effectively balance data dimensionality and model performance. Based on this, we put forward a triplet deep neural network model for customer credit scoring. This model makes use of the feature that deep neural networks and metric learning can efficiently extract and utilize data feature information so that two samples with the same label are embedded tightly while two samples with different labels are embedded loosely, so as to improve the accuracy of credit scoring. All experiments are conducted on three customer credit scoring datasets. We select accuracy, precision, recall, f1-score and AUC to evaluate the classification performance of all models. The experiments show that the triplet deep neural networks model can perform customer credit scoring more accurately compared with the now commonly used random forest (RF), deep neural networks (DNN), logistic regression (LR), k-nearest neighbor (KNN) and support vector machine (SVM).
深度神经网络以优异的性能广泛应用于语音识别、人脸验证等领域,并逐渐在客户信用评分领域得到应用和发展。传统的信用评分工作依赖于特征处理和模型构建两步建模过程,无法有效平衡数据维度和模型性能。在此基础上,提出了客户信用评分的三重深度神经网络模型。该模型利用深度神经网络和度量学习能够有效地提取和利用数据特征信息的特点,使具有相同标签的两个样本嵌入得紧密,而具有不同标签的两个样本嵌入得松散,从而提高信用评分的准确性。所有实验都是在三个客户信用评分数据集上进行的。我们选择准确率、精密度、召回率、f1-score和AUC来评估所有模型的分类性能。实验表明,与目前常用的随机森林(RF)、深度神经网络(DNN)、逻辑回归(LR)、k近邻(KNN)和支持向量机(SVM)相比,三元深度神经网络模型可以更准确地进行客户信用评分。

Self-supervised learning typically suffers from lacking contrastive pairs and extracting unrepresentative vectors. To handle above mentioned challenges, this paper introduces a novel self-supervised learning framework that integrates the location-based sampling manner and a well-designed dimensionality reduction module. In the location-based sampling module, this paper embeds a multi-crop sampling paradigm into the memory bank-based framework. In the dimensionality reduction module, this paper introduces a principal component dimensionality reduction to capture the most comprehensive features. Experiments on popular datasets demonstrate the superior performance of our proposed method.

Android applications (a.k.a., Android apps) have developed rapidly in the last decade, and have become an indispensable part in people's lives. However, it is challenging to guarantee their quality and reliability. The prevalence and severity of Android apps issues have driven the design and development of a number of detection and testing techniques. However, these techniques mainly target the generation of test sequences using GUI events in the applications, lacking of attentions to complex Android system configurations. In this paper, we conducted an in-depth study on real-world Android bugs related with configurations from 20 open-source popular Android applications, to help understand the characteristics of these bugs. We find the majority of configurations-related Android bugs would lead to catastrophic consequences, e.g., crash and hang. Based on the study, we design and implement ConfigDroid, a tool for configuration-aware GUI testing of Android applications. We use 10 open-source popular Android applications to evaluate the effectiveness. The result shows that, ConfigDroid can detect 4 more unique configuration-related crashes than state-of-the-art tools, Monkey and Stoat.
Android应用程序(又称安卓应用程序)在过去的十年中发展迅速,已经成为人们生活中不可或缺的一部分。然而,如何保证它们的质量和可靠性是一个挑战。Android应用程序问题的普遍性和严重性推动了许多检测和测试技术的设计和开发。然而,这些技术主要针对在应用程序中使用GUI事件生成测试序列,缺乏对复杂Android系统配置的关注。在本文中,我们深入研究了20个开源流行Android应用程序中与配置相关的真实Android漏洞,以帮助了解这些漏洞的特征。我们发现大多数与配置相关的Android漏洞会导致灾难性的后果,例如崩溃和挂起。在此基础上,设计并实现了基于配置感知的Android应用程序GUI测试工具ConfigDroid。我们使用10个开源的流行Android应用程序来评估其有效性。结果表明,ConfigDroid可以检测到比最先进的工具Monkey和Stoat更多的独特配置相关崩溃。

The path planning algorithm for moving objects has high complexity, and the automatic path planning ability is poor, which cannot deal with complex practical environmental problems. A fast path planning algorithm based on RRT-Star is proposed. First, for the diagonal obstacles in path planning, the deadlock back-off method is used to realize obstacle detection, which effectively improves the safety of the path. Second, as it progresses, the algorithm uses a step size adjustment function to expand the step size, thereby increasing the speed at which the random tree can explore this space. In addition, based on the RRT-Star algorithm, the target deviation strategy is introduced, and the initial pheromone allocation principle is proposed. Finally, the pheromone is classified, and the pheromone on each path is superimposed according to the optimization objective. The results show that the RRT-Star fast path planning efficiency and the number of iterations are significantly better than the RRT algorithm and the ant colony algorithm.
运动物体的路径规划算法复杂度高,自动路径规划能力差,无法处理复杂的实际环境问题。提出了一种基于RRT-Star的快速路径规划算法。首先,针对路径规划中的对角线障碍物,采用死锁回退方法实现障碍物检测,有效提高了路径的安全性;其次,随着算法的进展,算法使用步长调整函数来扩展步长,从而提高随机树探索该空间的速度。此外,在RRT-Star算法的基础上,引入了目标偏差策略,提出了初始信息素分配原则。最后对信息素进行分类,并根据优化目标对每条路径上的信息素进行叠加。结果表明,RRT- star快速路径规划效率和迭代次数明显优于RRT算法和蚁群算法。

Image denoising (DN), demosaicing (DM) and super-resolution (SR) are the key tasks of the low-level vision. Joint demosaicing, denoising and Super-resolution (JDDSR) can effectively improve the image quality. However, the previous methods explored the feasibility of tasks more than the characteristics of DM, DN and SR. Meanwhile, the joint training also brought computational burden and the three tasks process information at different frequencies. DN and DM pay more attention to low-frequency (LF) information, while SR is used to recover the lost high-frequency (HF) information. In this work, we use the way of Laplace pyramid to separate the HF and LF of the image, and use different branches to learn the information of different frequencies. In order to reduce the computational burden, we redesign the network architecture and use the form of non-parametric up-sampling to generate the results. Experiments demonstrate that our method can achieve results similar to existing methods with very small computational effort and storage.
图像去噪(DN)、去马赛克(DM)和超分辨率(SR)是低层次视觉的关键任务。联合去马赛克、去噪和超分辨率(JDDSR)可以有效地提高图像质量。然而,以往的方法探索的任务的可行性不仅仅是DM、DN和sr的特点,同时,联合训练也带来了计算负担,三种任务处理的信息频率不同。DN和DM更关注低频(LF)信息,而SR则用于恢复丢失的高频(HF)信息。在这项工作中,我们使用拉普拉斯金字塔的方式分离图像的高频和低频,并使用不同的分支来学习不同频率的信息。为了减少计算量,我们重新设计了网络结构,并采用非参数上采样的形式来生成结果。实验表明,该方法可以在很小的计算量和存储空间下获得与现有方法相似的结果。

Robust local feature detection and description are crucial in a huge of computer vision tasks. However, current feature descriptors lack geometric information and spatial features. In this paper, we propose a novel spatial and geometric feature fusion architecture, which can effectively tackle these problems. The proposed architecture includes three aspects. 1) A multiple low-level feature fusion (ML2F2) subnetworks, which could improve the ability to extract geometric information through the weighted fusion features. 2) A subnetwork for gradient feature extraction (GFE) which could validly extract the spatial features by encoding the horizontal and vertical gradients of an image. 3) Effective spatial geometric feature fusion (SGFF) module to alternatively fuse the above subnetworks. Experiments on the task of Image Matching and Long-Term Visual Localization show that the proposed method is superior to most advanced local feature descriptors.

With the promotion of the “new four automobile modernizations” and the rise of users' awareness of travel service demand, user experience has penetrated into the whole process from R & D (research and development) to sales of automotive products. Based on the questionnaire survey data, this paper uses K-means algorithm to subdivide new energy users. Firstly, factor analysis and principal component analysis are used to analyze users' values and career level, then K-means clustering is carried out on this basis, and user characteristics are visually analyzed. Finally, new energy users are divided into six categories, and the car purchase preferences of each category of users are deeply analyzed, which has important theoretical and practical significance for enterprises to accurately grasp users' needs and clarify the future research and development direction.
随着“新四化汽车”的推进和用户出行服务需求意识的提升,用户体验已经渗透到汽车产品从研发到销售的全过程。本文基于问卷调查数据,采用K-means算法对新能源用户进行细分。首先利用因子分析和主成分分析对用户的价值观和职业水平进行分析,然后在此基础上进行K-means聚类,对用户特征进行可视化分析。最后,将新能源用户划分为六大类,并对每一类用户的购车偏好进行深入分析,对于企业准确把握用户需求,明确未来的研发方向具有重要的理论和现实意义。
