Research on hands-free input methods has been actively conducted. However, most of the previous methods are difficult to use at any time in daily life due to using speech sounds or body movements. In this study, to realize a hands-free input method based on nasal breath using wearable devices, we propose a method for recognizing nasal breath gestures, using piezoelectric elements placed on the nosepiece of a glasses-type device. In the proposed method, nasal vibrations generated by nasal breath are acquired as sound data from the devices. Next, the breath pattern is recognized based on the factors of breath count, time interval, and intensity. We implemented a prototype system. The evaluation results for 10 subjects showed that the proposed method can recognize eight types of nasal breath gestures at 0.82% of F-value. The evaluation results also showed that the recognition accuracy is increased to more than 90% by limiting gestures to those with a different breath count or different breath interval. Our study provides the first glasses type wearable sensing technology that uses nasal breathing for hands-free input.
积极开展免提输入法研究。然而,由于使用语音或肢体动作,以往的方法大多难以在日常生活中随时使用。在本研究中,为了在可穿戴设备上实现基于鼻呼吸的免提输入法,我们提出了一种识别鼻呼吸手势的方法,该方法使用放置在眼镜型设备鼻支架上的压电元件。在提出的方法中,由鼻呼吸产生的鼻振动作为来自设备的声音数据被获取。接下来,根据呼吸计数、时间间隔和强度等因素来识别呼吸模式。我们实现了一个原型系统。对10名受试者的评价结果表明,该方法在0.82%的f值范围内可识别出8种鼻呼吸手势。评估结果还表明,通过对不同呼吸计数或不同呼吸间隔的手势进行限制,识别准确率提高到90%以上。我们的研究提供了第一种眼镜型可穿戴传感技术,该技术使用鼻腔呼吸进行免提输入。

We analyze and compare five deep-learning neural architectures to manage the problem of irony and sarcasm detection for the Italian language. We briefly analyze the model architectures to choose the best compromise between performances and complexity. The obtained results show the effectiveness of such systems to handle the problem by achieving 93% of F1-Score in the best case. As a case study, we also illustrate a possible embedding of the neural systems in a cloud computing infrastructure to exploit the computational advantage of using such an approach in tackling big data.

In Vitro Fertilization (IVF) is one of the scientifically known methods of infertility treatment. This study aimed at improving the performance of predicting the success of IVF using machine learning and its optimization through evolutionary algorithms. The Multilayer Perceptron Neural Network (MLP) were proposed to classify the infertility dataset. The Genetic algorithm was used to improve the performance of the Multilayer Perceptron Neural Network model. The proposed model was applied to a dataset including 594 eggs from 94 patients undergoing IVF, of which 318 were of good quality embryos and 276 were of lower quality embryos. For performance evaluation of the MLP model, an ROC curve analysis was conducted, and 10-fold cross-validation performed. The results revealed that this intelligent model has high efficiency with an accuracy of 96% for Multi-layer Perceptron neural network, which is promising compared to counterparts methods.

Sparse representation due to advantages such as noise-resistant and, having a strong mathematical theory, has been noticed as a powerful tool in recent decades. In this paper, using the sparse representation, kernel trick, and a different technique of the Region of Interest (ROI) extraction which we had presented in our previous work, a new and robust method against rotation is introduced for dorsal hand vein recognition. In this method, to select the ROI, by changing the length and angle of the sides, undesirable effects of hand rotation during taking images have largely been neutralized. So, depending on the amount of hand rotation, ROI in each image will be different in size and shape. On the other hand, because of the same direction distribution on the dorsal hand vein patterns, we have used the kernel trick on sparse representation to classification. As a result, most samples with different classes but the same direction distribution will be classified properly. Using these two techniques, lead to introduce an effective method against hand rotation, for dorsal hand vein recognition. Increases of 2.26% in the recognition rate is observed for the proposed method when compared to the three conventional SRC-based algorithms and three classification methods based sparse coding that used dictionary learning.
稀疏表示由于具有抗噪声和强大的数学理论等优点,在近几十年来已被视为一种强大的工具。在本文中,利用稀疏表示、核技巧和我们在先前工作中提出的不同的感兴趣区域(ROI)提取技术,提出了一种新的、抗旋转的鲁棒手背静脉识别方法。在这种方法中,通过改变侧面的长度和角度来选择ROI,在很大程度上消除了拍摄图像时手旋转的不良影响。因此,根据手的旋转量,每个图像中的ROI在大小和形状上都会有所不同。另一方面,由于手背静脉图案的方向分布相同,我们使用了稀疏表示的核技巧进行分类。因此,大多数具有不同类别但方向分布相同的样本将被正确分类。利用这两种技术,介绍了一种有效的防止手部旋转的手背静脉识别方法。与使用字典学习的三种传统的基于SRC的算法和三种基于稀疏编码的分类方法相比,所提出的方法的识别率提高了2.26%。

Improving Speed and Efficiency of Dynamic Programming Methods through Chaos 利用混沌提高动态规划方法的速度和效率
Pub Date : 2021-09-01 DOI: 10.22044/JADM.2021.10520.2191

A prominent weakness of dynamic programming methods is that they perform operations throughout the entire set of states in a Markov decision process in every updating phase. This paper proposes a novel chaos-based method to solve the problem. For this purpose, a chaotic system is first initialized, and the resultant numbers are mapped onto the environment states through initial processing. In each traverse of the policy iteration method, policy evaluation is performed only once, and only a few states are updated. These states are proposed by the chaos system. In this method, the policy evaluation and improvement cycle lasts until an optimal policy is formulated in the environment. The same procedure is performed in the value iteration method, and only the values of a few states proposed by the chaos are updated in each traverse, whereas the values of other states are left unchanged. Unlike the conventional methods, an optimal solution can be obtained in the proposed method by only updating a limited number of states which are properly distributed all over the environment by chaos. The test results indicate the improved speed and efficiency of chaotic dynamic programming methods in obtaining the optimal solution in different grid environments.
动态规划方法的一个突出弱点是,它们在每个更新阶段的马尔可夫决策过程中对整个状态集执行操作。本文提出了一种新的基于混沌的方法来解决这个问题。为此,首先对混沌系统进行初始化,并通过初始处理将所得数字映射到环境状态。在策略迭代方法的每次遍历中,策略评估只执行一次,并且只更新少数状态。这些状态是由混沌系统提出的。在这种方法中,策略评估和改进周期持续到在环境中制定最优策略为止。在值迭代方法中执行相同的过程,并且在每次遍历中只有混沌提出的少数状态的值被更新,而其他状态的值保持不变。与传统方法不同,该方法只需更新有限数量的状态即可获得最优解,这些状态通过混沌正确分布在整个环境中。测试结果表明,混沌动态规划方法在不同网格环境下获得最优解的速度和效率都有所提高。

In the structural software test, test data generation is essential. The problem of generating test data is a search problem, and for solving the problem, search algorithms can be used. Genetic algorithm is one of the most widely used algorithms in this field. Adjusting genetic algorithm parameters helps to increase the effectiveness of this algorithm. In this paper, the Adaptive Genetic Algorithm (AGA) is used to maintain the diversity of the population to test data generation based on path coverage criterion, which calculates the rate of recombination and mutation with the similarity between chromosomes and the amount of chromosome fitness during and around each algorithm. Experiments have shown that this method is faster for generating test data than other versions of the genetic algorithm used by others.

This research is related to the development of technology in the field of automatic text to image generation. In this regard, two main goals are pursued; first, the generated image should look as real as possible; and second, the generated image should be a meaningful description of the input text. our proposed method is a Multi Sentences Hierarchical GAN (MSH-GAN) for text to image generation. In this research project, we have considered two main strategies: 1) produce a higher quality image in the first step, and 2) use two additional descriptions to improve the original image in the next steps. Our goal is to focus on using more information to generate images with higher resolution by using more than one sentence input text. We have proposed different models based on GANs and Memory Networks. We have also used more challenging dataset called ids-ade. This is the first time; this dataset has been used in this area. We have evaluated our models based on IS, FID and, R-precision evaluation metrics. Experimental results demonstrate that our best model performs favorably against the basic state-of-the-art approaches like StackGAN and AttGAN.

Determining the personality dimensions of individuals is very important in psychological research. The most well-known example of personality dimensions is the Five-Factor Model (FFM). There are two approaches 1- Manual and 2- Automatic for determining the personality dimensions. In a manual approach, Psychologists discover these dimensions through personality questionnaires. As an automatic way, varied personal input types (textual/image/video) of people are gathered and analyzed for this purpose. In this paper, we proposed a method called DENOVA (DEep learning based on the ANOVA), which predicts FFM using deep learning based on the Analysis of variance (ANOVA) of words. For this purpose, DENOVA first applies ANOVA to select the most informative terms. Then, DENOVA employs Word2Vec to extract document embeddings. Finally, DENOVA uses Support Vector Machine (SVM), Logistic Regression, XGBoost, and Multilayer perceptron (MLP) as classifiers to predict FFM. The experimental results show that DENOVA outperforms on average, 6.91%, the state-of-the-art methods in predicting FFM with respect to accuracy.

Object Segmentation using Local Histograms, Invasive Weed Optimization Algorithm and Texture Analysis 基于局部直方图、入侵杂草优化算法和纹理分析的目标分割

Most of the methods proposed for segmenting image objects are supervised methods which are costly due to their need for large amounts of labeled data. However, in this article, we have presented a method for segmenting objects based on a meta-heuristic optimization which does not need any training data. This procedure consists of two main stages of edge detection and texture analysis. In the edge detection stage, we have utilized invasive weed optimization (IWO) and local thresholding. Edge detection methods that are based on local histograms are efficient methods, but it is very difficult to determine the desired parameters manually.

提出的用于分割图像对象的大多数方法都是有监督的方法,由于它们需要大量的标记数据,因此成本高昂。然而,在本文中,我们提出了一种基于元启发式优化的对象分割方法,该方法不需要任何训练数据。该过程包括边缘检测和纹理分析两个主要阶段。在边缘检测阶段,我们使用了入侵杂草优化(IWO)和局部阈值。基于局部直方图的边缘检测方法是有效的方法,但很难手动确定所需的参数。此外,必须为每个图像专门选择这些参数。本文提出了一种使用进化算法自动确定这些参数的方法。对该方法的评价表明,该方法在自然图像上具有较高的性能。

Wireless body area networks (WBAN) are innovative technologies that have been the anticipation greatly promote healthcare monitoring systems. All WBAN included biomedical sensors that can be worn on or implanted in the body. Sensors are monitoring vital signs and then processing the data and transmitting to the central server. Biomedical sensors are limited in energy resources and need an improved design for managing energy consumption. Therefore, DTEC-MAC (Diverse Traffic with Energy Consumption-MAC) is proposed based on the priority of data classification in the cluster nodes and provides medical data based on energy management. The proposed method uses fuzzy logic based on the distance to sink and the remaining energy and length of data to select the cluster head. MATLAB software was used to simulate the method. This method compared with similar methods called iM-SIMPLE and M-ATTEMPT, ERP. Results of the simulations indicate that it works better to extend the lifetime and guarantee minimum energy and packet delivery rates, maximizing the throughput.
无线身体区域网络(WBAN)是一种创新技术,有望极大地促进医疗保健监测系统的发展。所有WBAN都包括可以佩戴或植入体内的生物医学传感器。传感器正在监测生命体征,然后处理数据并传输到中央服务器。生物医学传感器的能源有限,需要改进设计以管理能源消耗。因此,基于集群节点中数据分类的优先级,提出了DTEC-MAC(Diverse Traffic with Energy Consumption MAC),并基于能量管理提供医疗数据。该方法使用基于下沉距离和剩余能量和数据长度的模糊逻辑来选择簇头。利用MATLAB软件对该方法进行了仿真。该方法与iM SIMPLE和M-ATTEMPT、ERP的类似方法进行了比较。仿真结果表明,它能更好地延长寿命,保证最小的能量和数据包传输速率,最大限度地提高吞吐量。
