Protein Folding Structure Prediction using Reinforcement Learning with Application to Both 2D and 3D Environments 基于强化学习的蛋白质折叠结构预测及其在二维和三维环境中的应用
Jason Lu
Proteins are critical for lives. They not only build 10%-35% of our body tissues, but also can be used to understand the structures of different viruses, and then help us to explore effective vaccines. Hence, predicting new protein structures is very important for human health. However, the structure of protein is complicated. Exploration using human experiments is cost-consuming. Recently, artificial intelligence (AI) technology, such as imitation learning and reinforcement learning (RL), has been rapidly developed and significantly improved the efficiency in many different domains. In this project, we will try to use RL to solve the protein folding structure prediction problem. First, we adopted the PH structure as a relatively simple representation of the protein structure, where different peptides can be categorized into two types: P(hydrophilic) and H(hydrophobic). The goal of the protein folding is to try to make more H pairs during the folding process. We then formulated the protein folding problem as a reinforcement learning process. If a new H pair is generated during folding, we collect -1 reward. Such RL reward is designed based on the protein dataset (Protein Data Bank). Finally, we implemented three RL algorithms: 1) Q-learning, 2) Deep Q-learning, and 3) Double Deep Q-learning (DDQN). We implemented and compared the three algorithms in terms of their accuracy and efficiency. We found that all three algorithms can accurately predict the structures of simple proteins. As protein structures become more complicated, the DDQN is performing better.
蛋白质对生命至关重要。它们不仅构成了我们身体组织的10%-35%,还可以用来了解不同病毒的结构,然后帮助我们探索有效的疫苗。因此,预测新的蛋白质结构对人类健康非常重要。然而,蛋白质的结构是复杂的。利用人体实验进行探索是非常昂贵的。近年来,人工智能(AI)技术,如模仿学习和强化学习(RL)得到了迅速发展,并显著提高了许多不同领域的效率。在这个项目中,我们将尝试使用RL来解决蛋白质折叠结构的预测问题。首先,我们采用PH结构作为蛋白质结构的相对简单的表示,其中不同的肽可以分为两种类型:P(亲水)和H(疏水)。蛋白质折叠的目的是在折叠过程中产生更多的H对。然后我们将蛋白质折叠问题表述为一个强化学习过程。如果在折叠过程中产生一个新的H对,我们将获得-1奖励。这种RL奖励是基于蛋白质数据集(蛋白质数据库)设计的。最后,我们实现了三种强化学习算法:1)Q-learning, 2)深度Q-learning和3)双深度Q-learning (DDQN)。我们实现并比较了这三种算法的精度和效率。我们发现这三种算法都能准确地预测简单蛋白质的结构。随着蛋白质结构变得越来越复杂,DDQN的性能也越来越好。

Software quality evaluation based on improved RAD model and AHP 基于改进的RAD模型和AHP的软件质量评价
Zuchuang Zheng, Shanliang Xue, Meijiao Xu, Mao-sheng Li, Ruxue Ma
Software testing is an important means to ensure software quality. The quality and efficiency of software testing can be greatly improved by modeled software testing. Software test maturity model (TMM) is a reference model to guide software organizations to improve test maturity. However, there is a lack of guidance on software testing objectives and process improvement, which leads to poor enforceability and low execution efficiency. To solve the above problems, based on the maturity objectives and content of the five test levels of the TMM model, an improved software testing V model (RAD) is proposed, and a software quality evaluation method is proposed for the improved RAD model.

Research on Image Information Restoration Algorithm of Printing Micro Dots Based on GAN 基于GAN的印刷微点图像信息恢复算法研究
Bo Yuan, Peng Cao
During printing and shooting, the degradation of printing micro dots significantly affects the decoding and reading of hidden anti-counterfeiting information. However, existing image restoration methods cannot effectively restore image information. Moreover, there are relatively few datasets related to halftone dot images, and most datasets differ from the real data. Therefore, we propose an end-to-end restoration model based on the single-image super-resolution information. Specifically, we constructed a PMD dataset for real printing of anti-counterfeiting scenes. Based on this dataset, we used the high-resolution image information as the target. The positional inclination of the degraded images is corrected using the blank and interline characteristics of the printing micro dots images. The restoration is completed with the help of feature extraction and upsample of ESRGAN. In addition, we propose evaluation measures suitable for error detection, correction, and decoding requirements for microscopic image information. The experimental results show that, within the noise tolerance range, the image information restored by our method has a maximum average bit error rate is 0.97% and a Euclidean distance is 0.00804 pixels, whereas traditional filtering measures cannot effectively restore image information. The experimental results verified the effectiveness and robustness of the proposed method.
在印刷和拍摄过程中,印刷微点的退化严重影响隐藏防伪信息的解码和读取。然而,现有的图像恢复方法不能有效地恢复图像信息。此外,与半色调网点图像相关的数据集相对较少,而且大多数数据集与真实数据存在差异。因此,我们提出了一种基于单幅图像超分辨率信息的端到端恢复模型。具体来说,我们构建了一个真实打印防伪场景的PMD数据集。在此数据集的基础上,我们以高分辨率图像信息为目标。利用打印微点图像的空白和行间特性对退化图像的位置倾斜进行校正。利用ESRGAN的特征提取和上采样完成恢复。此外,我们提出了适合于显微图像信息的错误检测、纠错和解码要求的评价措施。实验结果表明,在噪声容限范围内,该方法恢复的图像信息最大平均误码率为0.97%,欧氏距离为0.00804像素,而传统滤波措施无法有效恢复图像信息。实验结果验证了该方法的有效性和鲁棒性。

Multi-objective software test case selection based on density analysis 基于密度分析的多目标软件测试用例选择
Huihui Jia, Cheng Zhang, Sijie Wu
Software test case selection is committed to select the fewest test cases from test suites to perform a complete test at the least cost. Machine learning and multi-objective optimization techniques have developed rapidly in recent years, and they have been successfully applied to test case selection. In this paper, we present a method called DB-NSGA2, which uses the density clustering algorithm in machine learning combined with the non-dominated ranking algorithm (NSGA2) for test case selection, which can better select the test cases required for testing. In particular, we apply some of the clustering results generated by the clustering algorithm to the crossover and mutation operations of the NSGA2 to improve diversity progeny populations and ensure the transmission of good individuals. Extensive experiments show that the test cases selected by our method can produce a better set of Pareto solutions and can detect more faults at a lower cost than other methods.

A Failure Prediction Approach Supporting Multi Granularity Data Fusion for Large-scale Cloud Storage Systems 支持大规模云存储系统多粒度数据融合的故障预测方法
Yongyang Cheng, T. Zhang, Jing Luo
With the development of cloud computing and cloud storage technology, the data scale has grown rapidly. In order to store and process large-scale data, there are thousands of nodes and devices in the cloud storage center, resulting in a surge in the frequency of failures. In various types of failure events, storage device failure is the most important one. However, most cloud storage systems lack disk failure prediction mechanisms and could only replace disks after disk failures. It is particularly important to predict the potential risks in the system operation environment. In this paper, we propose a disk failure prediction approach that supports multi granularity data fusion, which solves problems of unbalanced samples, single data source, cross scenario model migration and insufficient generalization ability of prediction models in disk failure prediction. Through our proposed approach, the cloud storage system could accurately predict disk failures and actively push prediction results to users, so as to improve the pertinence and planning of the operation and maintenance work. The approach presented in this paper has been validated to be valid through a series of qualitative and quantitative experiments.
随着云计算和云存储技术的发展,数据规模迅速增长。为了存储和处理大规模数据,云存储中心有成千上万的节点和设备,导致故障频率激增。在各种类型的故障事件中,存储设备故障是最重要的一类。然而,大多数云存储系统缺乏硬盘故障预测机制,只能在硬盘故障后进行更换。对系统运行环境的潜在风险进行预测尤为重要。本文提出了一种支持多粒度数据融合的磁盘故障预测方法,解决了磁盘故障预测中样本不平衡、数据源单一、跨场景模型迁移以及预测模型泛化能力不足等问题。通过我们提出的方法,云存储系统可以准确预测硬盘故障,并主动将预测结果推送给用户,从而提高运维工作的针对性和计划性。通过一系列定性和定量实验,验证了本文方法的有效性。

Juntian Chen, Ruikang Luo
Abstract—With the development of vehicles and traffic system in the early 21st century, the need for a monitored traffic system and vehicle classification is enlarging. Together with the development of deep learning, computer vision realm has emerged versatile models that is able to fulfill the need of classification. Those popular models include CNN, Vision Trans- former, Metaformer and so on. However, these models handle the problem based on different data processing techniques, they either lacks efficiency or effectiveness. In particular, CNN is shortcoming in global data while ViT is lack of extraction of local information. Therefore, based on this research gap, we proposed a model called MetaCNN, which combines CNN and Poolformer – a specific metaformer structure, which takes the strength of the two models and compensate for both models’ deficiencies. Finally, in order to verify the feasibility of our model, we tested our model on a real-world remote sensing datasets of vehicle images in six different regions with different weather conditions. Our model MetaCNN has demonstrated better recognition performance compared to other baseline models.

摘要:21世纪初,随着车辆和交通系统的发展,对交通监控系统和车辆分类的需求越来越大。随着深度学习的发展,计算机视觉领域出现了能够满足分类需求的通用模型。目前比较流行的型号有CNN、Vision Trans- former、Metaformer等。然而,这些模型基于不同的数据处理技术来处理问题,它们要么缺乏效率,要么缺乏有效性。特别是CNN的缺点是对全局数据的提取,而ViT则缺乏对局部信息的提取。因此,基于这一研究空白,我们提出了一种名为MetaCNN的模型,该模型将CNN和Poolformer——一种特定的元former结构结合在一起,它吸收了两个模型的优点,弥补了两个模型的不足。最后,为了验证模型的可行性,我们在六个不同地区不同天气条件下的真实遥感车辆图像数据集上对模型进行了测试。与其他基线模型相比,我们的模型MetaCNN表现出更好的识别性能。结果进一步证明了我们的模型MetaCNN在复杂场景下能够很好地完成遥感图像的车辆分类

MAKT: A Knowledge Tracing Model Based on Meta Path and Attention Mechanism 基于元路径和注意机制的知识跟踪模型
Shaopeng Yang, Tiancheng Zhang, Siyuan Mao, Gensitskiy Yu., Yiming Sun
With the deep integration of artificial intelligence technology and education, the traditional educational pattern has changed hugely. And the adaptive learning based on automatically tracing the knowledge status of students at various stages has attracted much attention. As a key technology, knowledge tracing has become an important research. Although deep learning has been used in knowledge tracing and promoted certain performance improvement, it still has drawbacks. First, current researches consider less the explicit representation of meta path between users, exercise items and knowledge points, ignoring some of the higher-order information. Secondly, the effect of higher-order information of knowledge points on prediction is ignored. Therefore, we proposes a meta-path based four-way co-attention mechanism model MAKT to inversely infer the unobservable knowledge cognitive proficiency of learners. Based on meta path, the MAKT model integrates instance information and higher-order information between nodes to effectively enhance the representation of user, exercise item and knowledge points. The effectiveness of the model was demonstrated in tests on a real data set.
随着人工智能技术与教育的深度融合,传统的教育模式发生了巨大的变化。而基于自动跟踪学生各阶段知识状态的自适应学习也受到了广泛关注。知识追踪作为一项关键技术,已成为一个重要的研究方向。尽管深度学习在知识跟踪中得到了应用,并促进了一定的性能提升,但它仍然存在缺陷。首先,目前的研究较少考虑用户、练习项目和知识点之间元路径的显式表示,忽略了一些高阶信息。其次,忽略了知识点的高阶信息对预测的影响。因此,我们提出了一个基于元路径的四向共同注意机制模型MAKT来反向推断学习者的不可观察知识认知能力。MAKT模型基于元路径,集成实例信息和节点间的高阶信息,有效增强了用户、习题和知识点的表示。在实际数据集上的测试验证了该模型的有效性。

Detection of cervical vertebrae from infrared thermal imaging based on improved Yolo v3 基于改进Yolo v3的颈椎红外热成像检测
Yaqun Wang, Di Sun, Lei Liu, Luan Ye, Kaidi Fu, Xinyu Jin
Yolo has achieved great success in the field of image segmentation, and has been applied to infrared thermal imaging detection. However, in the feature pyramid for feature fusion, high-level spatial feature information is lost, and both high-level and low-level features have poor semantics. This paper proposes an infrared thermal imaging cervical spine part extraction method based on improved Yolo v3. In order to make up for the channel information lost in feature fusion, this paper convolves the high-level features, and then enhances the residual features to reduce the semantic loss caused by the number of channels by compensating for the spatial context information. To reduce the semantic gap of additive fusion, this paper applies an attention mechanism on low-level features. The improved Yolo v3 algorithm was used to extract the cervical vertebrae in infrared thermal images, and comparative experiments were completed. Experiments on the dataset collected in the cooperative hospital demonstrate that our proposed improved Yolo v3 achieves better performance.
Yolo在图像分割领域取得了巨大的成功,并已应用于红外热成像检测。然而,在特征融合的特征金字塔中,丢失了高层空间特征信息,高层和低层特征语义都很差。本文提出了一种基于改进Yolo v3的红外热成像颈椎部位提取方法。为了弥补特征融合中丢失的信道信息,本文首先对高级特征进行卷积,然后对残差特征进行增强,通过补偿空间上下文信息来减少信道数量造成的语义损失。为了减小加性融合的语义缺口,本文在底层特征上引入了注意机制。采用改进的Yolo v3算法提取红外热图像中的颈椎,并完成对比实验。在合作医院数据集上的实验表明,改进后的Yolo v3具有更好的性能。

However, in the feature pyramid for feature fusion, high-level spatial feature information is lost, and both high-level and low-level features have poor semantics. This paper proposes an infrared thermal imaging cervical spine part extraction method based on improved Yolo v3. In order to make up for the channel information lost in feature fusion, this paper convolves the high-level features, and then enhances the residual features to reduce the semantic loss caused by the number of channels by compensating for the spatial context information. To reduce the semantic gap of additive fusion, this paper applies an attention mechanism on low-level features. The improved Yolo v3 algorithm was used to extract the cervical vertebrae in infrared thermal images, and comparative experiments were completed.

An Image Enhancement Filtering Algorithm for Speckle Patterns 一种斑点图像增强滤波算法
Boyuan Yao, Ying Wu
Noise reduction is one of the most exciting problems in speckle pattern. We present an Image Enhancement Filtering Algorithm on experimental speckle correlation fringes and speckle image of cone respectively. In the algorithm, adaptively automatic threshold and gradient of the detecting pixel is calculated according to the mean value of the 3 × 3 area pixels around the detecting pixel and the human vision system. The results show that this technique is capable of significantly improving the quality patterns and enhancing the contrast with the edge of the speckle image, as well as preserving more detailed information of the cone.
噪声抑制是散斑图中最令人兴奋的问题之一。分别对实验散斑相关条纹和圆锥散斑图像提出了一种图像增强滤波算法。该算法根据检测像素周围3 × 3区域像素与人眼视觉系统的均值计算检测像素的自适应自动阈值和梯度。结果表明,该方法能够显著改善散斑图像的质量模式,增强与散斑图像边缘的对比度,并保留了更多的圆锥体的详细信息。
