装有传感器，执行器和电子控制单元（ECU）的现代车辆可以分为几个称为功能工作组（FWGS）的操作子系统。这些FWG的示例包括发动机系统，变速箱，燃油系统，制动器等。每个FWG都有相关的传感器通道，可以衡量车辆操作条件。这种丰富的数据环境有利于预测维护（PDM）技术的开发。削弱各种PDM技术的是需要强大的异常检测模型，该模型可以识别出明显偏离大多数数据的事件或观察结果，并且不符合正常车辆操作行为的明确定义的概念。在本文中，我们介绍了车辆性能，可靠性和操作（VEPRO）数据集，并使用它来创建一种基于多阶段的异常检测方法。利用时间卷积网络（TCN），我们的异常检测系统可以达到96％的检测准确性，并准确预测91％的真实异常。当利用来自多个FWG的传感器通道时，我们的异常检测系统的性能会改善。

人类免疫系统（HIS）致力于保护人体免受感染，疾病和疾病的侵害。该系统可以激发网络安全专业人员设计基于人造免疫系统（AIS）的入侵检测系统（IDS）。这些生物学启发的算法使用自我/非自然和危险理论可以直接增强设计和实现。在本文中，我们包括研究建立AIS-IDS框架所必需的设计元素，并提出一个建筑以创建此类系统。

随着基于人工智能（AI）和机器学习（ML）技术的实用性的增长，对抗性攻击的威胁越来越大。有必要将这个生态系统的团队红色团结起来，以确定系统漏洞，潜在威胁，表征将增强系统鲁棒性并鼓励创造有效防御的属性。次要的需求是在不同的利益相关者，模型开发人员，用户和AI/ML安全专业人员等不同的利益相关者之间分享此AI安全威胁情报。在本文中，我们创建并描述了原型系统CTI4AI，以克服有条不紊地识别和共享AI/ML特定漏洞和威胁智能的需求。

现代人工智能（AI）启用了入侵检测系统（IDS）是复杂的黑匣子。这意味着安全分析师对IDS模型为何做出特定预测的原因几乎没有解释或澄清。解决此问题的一个潜在解决方案是基于可解释的人工智能（XAI）的当前能力研究和开发可解释的入侵检测系统（X-IDS）。在本文中，我们创建了一个基于自组织的X-IDS系统，能够产生解释性的可视化。我们利用SOM的解释性来创建全球和本地解释。分析师可以使用全局解释来了解特定IDS如何计算预测的一般想法。为单个数据点生成了局部说明，以解释为什么计算某个预测值的原因。此外，使用NSL-KDD和CIC-IDS-2017数据集评估了我们基于SOM的X-IDS在解释生成和传统准确性测试中评估。

人工智能（AI）和机器学习（ML）在网络安全挑战中的应用已在行业和学术界的吸引力，部分原因是对关键系统（例如云基础架构和政府机构）的广泛恶意软件攻击。入侵检测系统（IDS）使用某些形式的AI，由于能够以高预测准确性处理大量数据，因此获得了广泛的采用。这些系统托管在组织网络安全操作中心（CSOC）中，作为一种防御工具，可监视和检测恶意网络流，否则会影响机密性，完整性和可用性（CIA）。 CSOC分析师依靠这些系统来决定检测到的威胁。但是，使用深度学习（DL）技术设计的IDS通常被视为黑匣子模型，并且没有为其预测提供理由。这为CSOC分析师造成了障碍，因为他们无法根据模型的预测改善决策。解决此问题的一种解决方案是设计可解释的ID（X-IDS）。这项调查回顾了可解释的AI（XAI）的最先进的ID，目前的挑战，并讨论了这些挑战如何涉及X-ID的设计。特别是，我们全面讨论了黑匣子和白盒方法。我们还在这些方法之间的性能和产生解释的能力方面提出了权衡。此外，我们提出了一种通用体系结构，该建筑认为人类在循环中，该架构可以用作设计X-ID时的指南。研究建议是从三个关键观点提出的：需要定义ID的解释性，需要为各种利益相关者量身定制的解释以及设计指标来评估解释的需求。

Mixup is a popular data augmentation technique for training deep neural networks where additional samples are generated by linearly interpolating pairs of inputs and their labels. This technique is known to improve the generalization performance in many learning paradigms and applications. In this work, we first analyze Mixup and show that it implicitly regularizes infinitely many directional derivatives of all orders. We then propose a new method to improve Mixup based on the novel insight. To demonstrate the effectiveness of the proposed method, we conduct experiments across various domains such as images, tabular data, speech, and graphs. Our results show that the proposed method improves Mixup across various datasets using a variety of architectures, for instance, exhibiting an improvement over Mixup by 0.8% in ImageNet top-1 accuracy.

Multi-Scale and U-shaped Networks are widely used in various image restoration problems, including deblurring. Keeping in mind the wide range of applications, we present a comparison of these architectures and their effects on image deblurring. We also introduce a new block called as NFResblock. It consists of a Fast Fourier Transformation layer and a series of modified Non-Linear Activation Free Blocks. Based on these architectures and additions, we introduce NFResnet and NFResnet+, which are modified multi-scale and U-Net architectures, respectively. We also use three different loss functions to train these architectures: Charbonnier Loss, Edge Loss, and Frequency Reconstruction Loss. Extensive experiments on the Deep Video Deblurring dataset, along with ablation studies for each component, have been presented in this paper. The proposed architectures achieve a considerable increase in Peak Signal to Noise (PSNR) ratio and Structural Similarity Index (SSIM) value.

A major direction in differentially private machine learning is differentially private fine-tuning: pretraining a model on a source of "public data" and transferring the extracted features to downstream tasks. This is an important setting because many industry deployments fine-tune publicly available feature extractors on proprietary data for downstream tasks. In this paper, we use features extracted from state-of-the-art open source models to solve benchmark tasks in computer vision and natural language processing using differentially private fine-tuning. Our key insight is that by accelerating training, we can quickly drive the model parameters to regions in parameter space where the impact of noise is minimized. In doing so, we recover the same performance as non-private fine-tuning for realistic values of epsilon in [0.01, 1.0] on benchmark image classification datasets including CIFAR100.

Nostradamus, inspired by the French astrologer and reputed seer, is a detailed study exploring relations between environmental factors and changes in the stock market. In this paper, we analyze associative correlation and causation between environmental elements and stock prices based on the US financial market, global climate trends, and daily weather records to demonstrate significant relationships between climate and stock price fluctuation. Our analysis covers short and long-term rises and dips in company stock performances. Lastly, we take four natural disasters as a case study to observe their effect on the emotional state of people and their influence on the stock market.

Health metrics from wrist-worn devices demand an automatic dominant hand prediction to keep an accurate operation. The prediction would improve reliability, enhance the consumer experience, and encourage further development of healthcare applications. This paper aims to evaluate the use of physiological and spatiotemporal context information from a two-hand experiment to predict the wrist placement of a commercial smartwatch. The main contribution is a methodology to obtain an effective model and features from low sample rate physiological sensors and a self-reported context survey. Results show an effective dominant hand prediction using data from a single subject under real-life conditions.
