Alzheimer's disease (AD), a kind of dementia, is marked by progressive cognitive and behavioural problems that appear in middle or late life. Alzheimer's disease must be detected early in order to create more effective therapies. Dr. Alois Alzheimer was the first doctor in the medical field to notice an unusual state of change in the brains of his deceased patients with mental illness, which marked the start of Alzheimer's study. Machine learning (ML) techniques nowadays employ a variety of probabilistic and optimization strategies to allow computers to learn from vast and complex datasets. Because of the limited number of labelled data and the prevalence of outliers in the current datasets, accurate dementia prediction is extremely difficult. In this research, we propose a sustainable framework for dementia prediction based on ML techniques such as Support Vector Machine, Decision Tree, AdaBoost, Random Forest, and XGmodel. All the experiments, in this literature, were conducted under the same experimental conditions using the longitudinal MRI Dataset.
阿尔茨海默病(AD)是痴呆症的一种,其特征是在中年或晚年出现渐进式认知和行为问题。为了创造更有效的治疗方法,阿尔茨海默病必须及早发现。阿洛伊斯·阿尔茨海默博士是医学界第一个注意到他的已故精神疾病患者的大脑发生了一种不寻常的变化的医生,这标志着阿尔茨海默病研究的开始。如今,机器学习(ML)技术采用各种概率和优化策略,使计算机能够从庞大而复杂的数据集中学习。由于标记数据的数量有限,并且当前数据集中普遍存在异常值,因此准确的痴呆症预测非常困难。在本研究中,我们提出了一个基于ML技术(如支持向量机、决策树、AdaBoost、随机森林和xg模型)的可持续痴呆预测框架。本文献中的所有实验都是在相同的实验条件下使用纵向MRI数据集进行的。

Blockchain-based cryptocurrency has attracted the immersive attention of individuals and businesses. With distributed ledger technology (DLT) consisting of growing list of record blocks and securely linked together using cryptography, each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. The timestamp proves that the transaction data existed when the block was created. Since each block contains information about the block previous to it, they effectively form a chain, with each additional block linking to the ones before it. Consequently, blockchain transactions are irreversible in that, once they are recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks. The blockchain-based technologies have been emerging with a fleet speed. In this paper, the trustworthy Artificial Intelligence will be explored for blockchain-based cryptocurrency where the prohibitive price leap creates a challenge for financial analysis and prediction.
基于区块链的加密货币吸引了个人和企业的沉浸式关注。分布式账本技术(DLT)由不断增长的记录块列表组成,并使用加密技术安全地链接在一起,每个块包含前一个块的加密散列、时间戳和交易数据。时间戳证明在区块创建时存在交易数据。由于每个区块都包含前一个区块的信息,因此它们有效地形成了一个链,每个额外的区块都链接到它之前的区块。因此,区块链交易是不可逆的,因为一旦它们被记录下来,任何给定块中的数据都不能在不改变所有后续块的情况下进行追溯性更改。基于区块链的技术以飞快的速度出现。在本文中,将探索基于区块链的加密货币的可信赖人工智能,其中令人望而却步的价格飞跃为财务分析和预测带来了挑战。

Robust Discriminative Non-Negative Matrix Factorization with Maximum Correntropy Criterion 基于最大熵准则的鲁棒判别非负矩阵分解

Non-negative matrix factorization (NMF) is an effective dimension reduction tool widely used in pattern recognition and computer vision. However, conventional NMF models are neither robust enough, as their objective functions are sensitive to outliers, nor discriminative enough, as they completely ignore the discriminative information in data. In this paper, we proposed a robust discriminative NMF model (RDNMF) for learning an effective discriminative subspace from noisy dataset. In particular, RDNMF approximates observations by their reconstructions in the subspace via maximum correntropy criterion to prohibit outliers from influencing the subspace. To incorporate the discriminative information, RDNMF builds adjacent graphs by using maximum correntropy criterion based robust representation, and regularizes the model by margin maximization criterion. We developed a multiplicative update rule to optimize RDNMF and theoretically proved its convergence. Experimental results on popular datasets verify the effectiveness of RDNMF comparing with conventional NMF models, discriminative NMF models, and robust NMF models.
非负矩阵分解(NMF)是一种有效的降维工具,广泛应用于模式识别和计算机视觉。然而,传统的NMF模型鲁棒性不够强,因为其目标函数对异常值敏感,而判别性也不够强,因为它们完全忽略了数据中的判别信息。本文提出了一种鲁棒判别NMF模型(RDNMF),用于从噪声数据集中学习有效的判别子空间。特别是,RDNMF通过最大熵准则在子空间中的重建来近似观测值,以禁止异常值影响子空间。为了融合判别信息,RDNMF采用基于最大相关系数准则的鲁棒表示构建相邻图,并采用边界最大化准则对模型进行正则化。提出了一种优化RDNMF的乘法更新规则,并从理论上证明了其收敛性。在常用数据集上的实验结果验证了RDNMF与传统NMF模型、判别NMF模型和鲁棒NMF模型的有效性。

Family conflicts between parents and their children are nothing new and are something experienced by many in such situations [1]. These conflicts can even be exacerbated by cultural differences that exist between the two parties, especially in cases where the parents and child were raised in different countries, cultures and/or generations [2]. This description illustrates my personal experiences of conflict with my parents, which is what inspired me to create this app: The Problem Solver app. The app differs from other methods that could be applied to resolve these conflicts in that it facilitates more direct communication between the two conflicting parties, which would hopefully result in a more rapid and successful conflict resolution [3]. Naturally, there were challenges I faced in the making of the app, but I was eventually able to work through these and build a working product. I will also explore some related works and research into this topic that were helpful in supporting the idea that cultural differences between differently raised generations can have an impact on familial relations [4]. Then, I give a general overview of the system of the app and finally delve into possible limitations of the app and further steps I could take in the development of the app.
父母和孩子之间的家庭冲突并不是什么新鲜事,很多人在这种情况下都经历过[1]。双方之间存在的文化差异甚至会加剧这些冲突,特别是在父母和孩子在不同的国家、文化和/或世代中长大的情况下[2]。这一描述说明了我与父母发生冲突的个人经历,这也是我创造这个应用程序的灵感:问题解决者应用程序。这个应用程序与其他解决这些冲突的方法不同,它促进了冲突双方之间更直接的沟通,从而有望更快、更成功地解决冲突[3]。当然,在制作这款应用的过程中我也遇到了一些挑战,但我最终还是克服了这些困难,制作出了一款可行的产品。我还将探讨一些相关的工作和研究,这些工作和研究有助于支持不同世代之间的文化差异会影响家庭关系的观点[4]。然后,我对应用程序的系统进行了总体概述,最后深入研究了应用程序可能存在的局限性以及我在应用程序开发中可以采取的进一步步骤。

In explainable AI (XAI) for deep learning, saliency maps, heatmaps, or attention maps are commonly used to identify important regions for the classification of images of explanations. Recent research has shown that many common XAI methods do not accurately identify the regions that human experts consider important. We propose averaging explanations from ensembles of learners to increase the accuracy of explanations. Our technique is general and can be used with multiple deep learning architectures and multiple XAI algorithms. We show that this method decreases the difference between regions of interest of XAI algorithms and those identified by human experts. Furthermore, we show that human experts prefer the explanations produced by ensembles to those of individual networks.
在深度学习的可解释人工智能(XAI)中,显著性图、热图或注意力图通常用于识别解释图像分类的重要区域。最近的研究表明,许多常见的XAI方法不能准确地识别人类专家认为重要的区域。我们建议从学习者集合中平均解释,以提高解释的准确性。我们的技术是通用的,可以用于多种深度学习架构和多种XAI算法。我们表明,这种方法减少了XAI算法与人类专家识别的感兴趣区域之间的差异。此外,我们表明,人类专家更喜欢由整体产生的解释而不是单个网络产生的解释。

Word Predictability is Based on Context - and/or Frequency 单词的可预测性是基于上下文和/或频率的

In this paper we present an experiment carried out with BERT on a small number of Italian sentences taken from two domains: newspapers and poetry domain. They represent two levels of increasing difficulty in the possibility to predict the masked word that we intended to test. The experiment is organized on the hypothesis of increasing difficulty in predictability at the three levels of linguistic complexity that we intend to monitor: lexical, syntactic and semantic level. To test this hypothesis we alternate canonical and non-canonical versions of the same sentence before processing them with the same DL model. The result shows that DL models are highly sensitive to presence of non-canonical structures and to local non-literal meaning compositional effect. However, DL are also very sensitive to word frequency by predicting preferentially function vs content words, collocates vs infrequent word phrases. To measure differences in performance we created a linguistically based “predictability parameter” which is highly correlated with a cosine based classification but produces better distinctions between classes.
在本文中,我们提出了一个用BERT对两个领域的少量意大利语句子进行的实验:报纸和诗歌领域。它们代表了预测我们想要测试的掩蔽词的难度增加的两个层次。本实验是在我们打算监测的三个语言复杂性水平(词汇、句法和语义水平)的可预测性难度增加的假设上组织的。为了验证这一假设,我们在使用相同的DL模型处理相同句子之前,交替使用同一句子的规范和非规范版本。结果表明,深度学习模型对非正则结构的存在和局部非字面意义组成效应高度敏感。然而,深度学习对词频也非常敏感,通过优先预测功能词与内容词、搭配词与不常用的词短语。为了衡量性能差异,我们创建了一个基于语言的“可预测性参数”,它与基于余弦的分类高度相关,但可以更好地区分类别。

Cartoons are an important art style, which not only has a unique drawing effect but also reflects the character itself, which is gradually loved by people. With the development of image processing technology, people's research on image research is no longer limited to image recognition, target detection, and tracking, but also images In this paper, we use deep learning based image processing to generate cartoon caricatures of human faces. Therefore, this paper investigates the use of deep learning-based methods to learn face features and convert image styles while preserving the original content features, to automatically generate natural cartoon avatars. In this paper, we study a face cartoon generation method based on content invariance. In the task of image style conversion, the content is fused with different style features based on the invariance of content information, to achieve the style conversion.
动画片是一种重要的艺术风格,它不仅具有独特的绘画效果,而且还能反映人物本身,逐渐受到人们的喜爱。随着图像处理技术的发展,人们对图像的研究已经不再局限于图像识别、目标检测、跟踪,而是对图像的研究。本文采用基于深度学习的图像处理技术生成人脸卡通漫画。因此,本文研究利用基于深度学习的方法,在保留原始内容特征的情况下,学习人脸特征并转换图像样式,自动生成自然的卡通化身。本文研究了一种基于内容不变性的人脸卡通生成方法。在图像样式转换任务中,基于内容信息的不变性,将内容与不同的样式特征融合在一起,实现样式转换。

In recent years, we have seen a huge increase in air conditioning usage [4]. However, much of this energy put into air conditioning is being wasted, which contributes to a far less environmentally friendly world and is inconvenient for many [5][6]. This paper develops a smart vent and a mobile app to regulate temperatures in different rooms of a home to create an efficient solution to save energy. This conservation of energy allows both the environment to be preserved as well as the financial burden of families in need to be alleviated. Controlled studies of the system provide evidence of the system's automated ability to be energy efficient.
近年来,我们看到空调的使用量大幅增加。然而,大部分用于空调的能源被浪费了,这导致了一个远不环保的世界,并给许多人带来了不便。本文开发了一个智能通风口和一个移动应用程序来调节家中不同房间的温度,以创造一个有效的节能解决方案。这种节约能源的做法既可以保护环境,也可以减轻有需要的家庭的经济负担。对该系统的受控研究提供了该系统自动化节能能力的证据。

Deep learning has been increasingly used in various applications such as image and video recognition, recommender systems, image classification, image segmentation, medical image analysis, natural language processing, brain–computer interfaces, and financial time series. In deep learning, a convolutional neural network (CNN) is regularized versions of multilayer perceptrons. Multilayer perceptrons usually mean fully connected networks, that is, each neuron in one layer is connected to all neurons in the next layer. The full connectivity of these networks makes them prone to overfitting data. Typical ways of regularization, or preventing overfitting, include penalizing parameters during training or trimming connectivity. CNNs use relatively little pre-processing compared to other image classification algorithms. Given the rise in popularity and use of deep neural network learning, the problem of tuning hyperparameters is increasingly prominent tasks in constructing efficient deep neural networks. In this paper, the tuning of deep neural network learning (DNN) hyper-parameters is explored using an evolutionary based approach popularized for use in estimating solutions to problems where the problem space is too large to get an exact solution.
深度学习已经越来越多地应用于图像和视频识别、推荐系统、图像分类、图像分割、医学图像分析、自然语言处理、脑机接口和金融时间序列等各种应用中。在深度学习中,卷积神经网络(CNN)是多层感知器的正则化版本。多层感知器通常意味着完全连接的网络,即一层中的每个神经元都连接到下一层的所有神经元。这些网络的完全连接使它们容易产生过拟合数据。典型的正则化或防止过拟合的方法包括在训练期间惩罚参数或修剪连通性。与其他图像分类算法相比,cnn使用的预处理相对较少。随着深度神经网络学习的普及和应用,超参数的整定问题日益成为构建高效深度神经网络的重要任务。在本文中,深度神经网络学习(DNN)超参数的调优使用一种基于进化的方法进行了探索,这种方法被广泛用于估计问题空间太大而无法获得精确解的问题的解。
