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.

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.

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.

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. A set of designed variants of the model was analyzed statistically, which led to recommend specific settings while building the model. Experimental results show that learning and dropout rates influence the model’s performance the most, while deeper and wider networks did not enhance the performance despite the extended cost of training.

Facial expression recognition in the wild is challenging due to various unconstrained conditions. Although existing facial expression classifiers have been almost perfect on analyzing constrained frontal faces, they fail to perform well on partially occluded faces common in the wild. In this paper, an improved facial expression recognition technique, patch-based multiple local binary pattern (LBP) descriptor, comprises three and four patch LBPs [TPLBP, FPLBP]. The two-dimensional discrete cosine transform (DCT) was applied over the entire coded TPLBP and FPLBP face image as a feature extractor. The experiment results show that the proposed technique achieves a better recognition rate than state-of-the-art techniques. Oulu-CASIA dataset facial expression images have been evaluated using a support vector machine (SVM) classifier resulted in an accuracy of 92.1%.
由于各种不受约束的条件，在野外进行面部表情识别具有挑战性。尽管现有的面部表情分类器在分析受约束的正面人脸方面几乎是完美的，但它们在分析自然环境中常见的部分遮挡人脸时却表现不佳。本文提出了一种改进的面部表情识别技术——基于patch的多局部二值模式描述符(multiple local binary pattern, LBP)，包括3个和4个patch LBP [TPLBP, FPLBP]。将二维离散余弦变换(DCT)作为特征提取器应用于整个编码的TPLBP和FPLBP人脸图像。实验结果表明，该方法取得了较好的识别率。使用支持向量机(SVM)分类器对Oulu-CASIA数据集的面部表情图像进行了评估，准确率达到92.1%。
