Android ransomware is a threatening malware that is targeting individuals and enterprises. Many existing approaches suggested different ransomware detection solutions to protect users’ devices and data. These solutions used mainly static-based or dynamic-based analysis systems. However, the current solutions have considered only the old versions of Android platforms. In this paper, an efficient machine learning-based ransomware detection approach is proposed. This approach has studied deeply the latest version of Android (Version 11, API Level 30) to include the updated list of features including permissions and API packages calls that might be utilized by ransomware attacks. A new dataset was created after parsing 1000 apps to extract these features. Afterwards, different machine learning techniques were executed to generate different predictive models for Andoird ransomware. Some predictive models reached 98.3% of detection accuracy even after reducing around 26% of the overall features set.
安卓勒索软件是一种针对个人和企业的威胁性恶意软件。许多现有的方法提出了不同的勒索软件检测解决方案,以保护用户的设备和数据。这些解决方案主要使用基于静态或基于动态的分析系统。然而,目前的解决方案只考虑了旧版本的Android平台。本文提出了一种基于机器学习的高效勒索软件检测方法。这种方法深入研究了最新版本的Android(版本11,API Level 30),包括可能被勒索软件攻击利用的权限和API包调用等更新的功能列表。在分析了1000个应用程序以提取这些特征后,创建了一个新的数据集。之后,使用不同的机器学习技术生成不同的andiird勒索软件预测模型。一些预测模型在减少了大约26%的总体特征集之后,仍然达到了98.3%的检测准确率。

Audio Cochleogram with Analysis and Synthesis Banks Using 1D Convolutional Networks 使用1D卷积网络的音频耳蜗图分析和合成库

Time-Frequency transformation and spectral representations of audio signals are commonly used in various machine learning applications. Training a network on features such as the Mel-Spectrogram or Cochleogram has been proven more effective than training on time samples. In practical realizations, these are generated on a separate processor or pre-computed and stored on disk, requiring additional efforts and making it difficult to experiment with different variants. In this paper, we provide a PyTorch framework for generating the Cochleogram as well as the time-domain complex filter-banks for analysis and re-synthesis using the built-in trainable conv1d() layer. This allows computing this spectral feature on the fly as part of a larger network and enables experimenting with varying parameters. The analysis / synthesis banks enable building a trainable network that operates on complex subbands, where resynthesizing the time samples is desirable. The convolutional kernels may be trained from random values, or may be initialized and frozen or initialized and continuously trained with the rest of any network they are part of.
音频信号的时频变换和频谱表示通常用于各种机器学习应用。用梅尔谱图或耳蜗图等特征训练网络已被证明比用时间样本训练更有效。在实际实现中,这些是在单独的处理器上生成的,或者是预先计算并存储在磁盘上的,这需要额外的努力,并且很难试验不同的变体。在本文中,我们提供了一个PyTorch框架来生成耳蜗图,以及使用内置可训练的conv1d()层进行分析和重新合成的时域复杂滤波器组。这允许作为更大网络的一部分在飞行中计算光谱特征,并允许对不同参数进行实验。分析/合成库能够构建在复杂子带上运行的可训练网络,其中需要重新合成时间样本。卷积核可以从随机值中训练,也可以初始化并冻结,或者初始化并与它们所在的任何网络的其余部分一起连续训练。

Wireless sensor networks have become so popular in many applications such as vehicle tracking and monitoring, environmental measurements and radiation analysis. These applications can be ready to go for further processing by connecting it to remote servers through protocols that outside world used such as internet. This brings IPv6 over low power wireless sensor network (6LowPAN) into very important role to develop a bridge between internet and WSN network. Though a reliable communication demands many parameters such as data rate, effective data transmission, data security as well as packet size etc. A gateway between 6lowPAN network and IPV6 is needed where frame size compression is required in order to increase payload of data frame on hardware platform.

Data security and privacy act vital tasks in our daily lives. Traditional cryptosystems may be hacked amidst the growth of quantum resources. Consequently, we need new cryptosystems its construction is based on quantum concepts. In this work, we proposed a novel image cryptosystem using quantum walks. We employ a diversity of tools for experimental assessment of the presented cryptosystem including correlation analysis, histogram analysis, Shannon entropy analysis, UACI and NPCR analyses, Key sensitivity analysis, and occlusion analysis. These metrics show the advantages of our cryptosystem over some robust state-of-art cryptosystems.

The diagnosis of interactions between two drugs is an essential procedure in drug development. Many medical tool’s offer inclusive records related to DDI. However, this tool’s results are not very satisfactory. The main aim is to propose an efficient approach based on pattern matching that identifies the interaction between two drugs. In this study, the goal is to collect the data from the DrugBank, which is a publicly available source. The drug-related data includes drug ID, drug names, and various kinds of sentences of drug-drug interaction. Drug names will be identified by drug names dictionary defined in the corpus, and sentences will be determined according to given patterns. These sentences will treat as input data, and preprocessing steps will perform in these sentences. Various types of features are selected for machine learning classification. Then all the attributes will be classified into desired classes. The proposed method gains 95.4% accuracy from the random forest classifier.

Plant counting in major grain crops like wheat through aerial images still poses a challenge due to the very high infield density of plants and occlusion. Annotation of aerial images for counting through perfect detection or segmentation is extremely difficult due to a large number of extremely small plant instances. In this paper, we present a semi-supervised method based on cross-consistency for the semantic segmentation of field images and an inception-based regression network for plant counting. Through loosely semantic segmentation, tiny plant clusters are extracted from the RGB image and fed to a regression network to get the count. Cross-consistency under the cluster assumption is a powerful semi-supervised training technique to leverage the unlabeled images. In this work, it is observed that regions with lower density are more detectable within hidden representations as compared to inputs. Supervised training of an encoder in a shared fashion and the main decoder is carried out on the RGB images and the corresponding mask. Consistency between the prediction of main and auxiliary decoders is imposed to leverage the unlabeled images. Induction of inception in the regression network benefits in extracting the multi-scale features which are very important because of quite tiny plant instances as compared to the whole image. The proposed plant counting framework achieves very high performance having a standard deviation of 0.94 and a mean of 0.87 of absolute difference in the count given the semi-supervised nature. Our network has performed reasonably well as compared to supervised detection and segmentation-based counting framework. Moreover, labeling for detection or segmentation is a quite tedious task, so our network has the leverage to train the model with few labeled and large numbers of unlabeled images which also provides the advantage to train the system for other crops like rice and maize with few labeled images.
由于植物的内场密度和遮挡非常高,通过航空图像对小麦等主要粮食作物进行植物计数仍然存在挑战。由于航拍图像中存在大量极小的植物实例,因此通过完美的检测或分割对航拍图像进行标注进行计数是非常困难的。在本文中,我们提出了一种基于交叉一致性的半监督方法用于田间图像的语义分割,并提出了一种基于初始化的回归网络用于植物计数。通过松散语义分割,从RGB图像中提取微小植物簇,并将其输入回归网络进行计数。聚类假设下的交叉一致性是一种有效利用未标记图像的半监督训练技术。在这项工作中,观察到与输入相比,密度较低的区域在隐藏表示中更容易被检测到。在RGB图像和相应的掩码上以共享方式对编码器和主解码器进行监督训练。主解码器和辅助解码器预测之间的一致性是强加的,以利用未标记的图像。在回归网络中引入初始化有利于提取多尺度特征,这是非常重要的,因为与整个图像相比,植物实例非常小。所提出的植物计数框架实现了非常高的性能,在给定半监督性质的情况下,其绝对计数差的标准偏差为0.94,平均值为0.87。与监督检测和基于分割的计数框架相比,我们的网络表现得相当好。此外,标记用于检测或分割是一项相当繁琐的任务,因此我们的网络具有使用少量标记和大量未标记图像训练模型的优势,这也为使用少量标记图像训练其他作物(如水稻和玉米)的系统提供了优势。

On the Sensitivity of Residual Networks for Time Series Classification 残差网络在时间序列分类中的敏感性研究

Time series classification (TCS) is an essential task in many applications. There have been different models proposed for TSC where deep learning models proved to be an excellent option. However, deep learning models' performance is generally known to be highly affected by the settings of their architectural design decisions and values of corresponding hyperparameters. In this research, we study the impact of such decisions and values on Residual Neural Networks (ResNets), a leading deep learning model for TSC. The study considered four factors to be investigated those are the model’s depth and width besides learning and dropout rates. The interplay between the characteristics of time series data and these factors has been looked at as well.

时间序列分类(TCS)在许多应用中都是一项重要的任务。对于TSC已经提出了不同的模型,其中深度学习模型被证明是一个很好的选择。然而,深度学习模型的性能通常受到其架构设计决策设置和相应超参数值的高度影响。在这项研究中,我们研究了这些决策和价值观对残差神经网络(ResNets)的影响,这是TSC的一种领先的深度学习模型。该研究考虑了四个因素,即模型的深度和宽度,以及学习和辍学率。时间序列数据的特征与这些因素之间的相互作用也被研究过。对模型的一组设计变量进行统计分析,从而在构建模型时推荐特定的设置。实验结果表明,学习率和辍学率对模型的性能影响最大,而深度和广度的网络虽然增加了训练成本,但并没有提高模型的性能。

There have been different models proposed for TSC where deep learning models proved to be an excellent option. However, deep learning models' performance is generally known to be highly affected by the settings of their architectural design decisions and values of corresponding hyperparameters. In this research, we study the impact of such decisions and values on Residual Neural Networks (ResNets), a leading deep learning model for TSC. The study considered four factors to be investigated those are the model’s depth and width besides learning and dropout rates. The interplay between the characteristics of time series data and these factors has been looked at as well.

Graph are ubiquitous because the fields of application are varied. Well-known examples are social networks, biological networks and path-finding in road networks. Real-world graphs processing is very challenging because of 4V characteristics related to big data. They are huge to process them on single-node and the time complexity is exponential. Unfortunately, due to the lack of research, only a few systems are able to ensure the storage and quick processing of large-scale graphs. In this paper, we propose HGraph, a parallel and distributed tool which handles large-scale graphs. HGraph is build on top of Hadoop and Spark frameworks. The proposed tool provides high scalability and is adapted to easily implement algorithms for various graph problems. Experimental tests performed on real-world graphs showed that HGraph is reliable and achieves significant gain time over the state of the art of graph processing systems.
由于应用领域的多样性,图形无处不在。众所周知的例子是社会网络、生物网络和道路网络中的寻路。由于与大数据相关的4V特性,现实世界的图形处理非常具有挑战性。在单节点上处理它们是巨大的,而且时间复杂度是指数级的。遗憾的是,由于缺乏研究,只有少数系统能够保证大规模图形的存储和快速处理。在本文中,我们提出了HGraph,一个并行和分布式的工具,用于处理大规模的图。HGraph是建立在Hadoop和Spark框架之上的。该工具具有较高的可扩展性,可以很容易地实现各种图问题的算法。在真实世界的图形上进行的实验测试表明,HGraph是可靠的,并且在图形处理系统的技术状态下实现了显著的增益时间。
