数据转换（DT）是将原始数据转换为支持特定分类算法的形式的过程，并有助于分析特殊目的的数据。为了提高预测性能，我们调查了各种数据变换方法。本研究在电信行业（TCI）中的客户流失预测（CCP）背景下进行，客户疲劳是一种常见的现象。我们提出了一种与CCP问题的机器学习模型相结合的数据转换方法的新方法。我们在公开的TCI数据集中进行了实验，并在广泛使用的评估措施方面评估了性能（例如，AUC，精确，召回和F测量）。在这项研究中，我们提出了全面的比较来肯定转化方法的影响。比较结果和统计检验证明，大多数所提出的基于数据转换的优化模型显着提高了CCP的性能。总的来说，通过这份手稿介绍了电信行业的有效和优化的CCP模型。

肺癌是最致命的癌症之一，部分诊断和治疗取决于肿瘤的准确描绘。目前是最常见的方法的人以人为本的分割，须遵守观察者间变异性，并且考虑到专家只能提供注释的事实，也是耗时的。最近展示了有前途的结果，自动和半自动肿瘤分割方法。然而，随着不同的研究人员使用各种数据集和性能指标验证了其算法，可靠地评估这些方法仍然是一个开放的挑战。通过2018年IEEE视频和图像处理（VIP）杯竞赛创建的计算机断层摄影扫描（LOTUS）基准测试的肺起源肿瘤分割的目标是提供唯一的数据集和预定义的指标，因此不同的研究人员可以开发和以统一的方式评估他们的方法。 2018年VIP杯始于42个国家的全球参与，以获得竞争数据。在注册阶段，有129名成员组成了来自10个国家的28个团队，其中9个团队将其达到最后阶段，6队成功完成了所有必要的任务。简而言之，竞争期间提出的所有算法都是基于深度学习模型与假阳性降低技术相结合。三种决赛选手开发的方法表明，有希望的肿瘤细分导致导致越来越大的努力应降低假阳性率。本次竞争稿件概述了VIP-Cup挑战，以及所提出的算法和结果。

肺癌是世界大多数国家的死亡原因。由于提示肿瘤的诊断可以允许肿瘤学家辨别他们的性质，类型和治疗方式，CT扫描图像的肿瘤检测和分割是全球的关键研究领域。本文通过在Lotus DataSet上应用二维离散小波变换（DWT）来接近肺肿瘤分割，以进行更细致的纹理分析，同时将来自相邻CT切片的信息集成到馈送到深度监督的多路仓模型之前。在训练网络的同时，学习速率，衰减和优化算法的变化导致了不同的骰子共同效率，其详细统计数据已经包含在本文中。我们还讨论了此数据集中的挑战以及我们选择如何克服它们。本质上，本研究旨在通过试验多个适当的网络来最大化从二维CT扫描切片预测肿瘤区域的成功率，导致骰子共同效率为0.8472。

心血管疾病是世界各地最常见的死亡原因。为了检测和治疗心脏相关的疾病，需要连续血压（BP）监测以及许多其他参数。为此目的开发了几种侵入性和非侵入性方法。用于持续监测BP的医院中使用的大多数现有方法是侵入性的。相反，基于袖带的BP监测方法，可以预测收缩压（SBP）和舒张压（DBP），不能用于连续监测。几项研究试图从非侵​​入性可收集信号（例如光学肌谱（PPG）和心电图（ECG））预测BP，其可用于连续监测。在这项研究中，我们探讨了自动化器在PPG和ECG信号中预测BP的适用性。在12,000岁的MIMIC-II数据集中进行了调查，发现了一个非常浅的一维AutoEncoder可以提取相关功能，以预测与最先进的SBP和DBP在非常大的数据集上的性能。从模拟-II数据集的一部分的独立测试分别为SBP和DBP提供了2.333和0.713的MAE。在40个主题的外部数据集上，模型在MIMIC-II数据集上培训，分别为SBP和DBP提供2.728和1.166的MAE。对于这种情况来说，结果达到了英国高血压协会（BHS）A级并超越了目前文学的研究。

近年来，基于生理信号的认证表现出伟大的承诺，因为其固有的对抗伪造的鲁棒性。心电图（ECG）信号是最广泛研究的生物关像，也在这方面获得了最高的关注。已经证明，许多研究通过分析来自不同人的ECG信号，可以识别它们，可接受的准确性。在这项工作中，我们展示了EDITH，EDITH是一种基于深入的ECG生物识别认证系统的框架。此外，我们假设并证明暹罗架构可以在典型的距离指标上使用，以提高性能。我们使用4个常用的数据集进行了评估了伊迪丝，并使用少量节拍表现优于先前的工作。 Edith使用仅单一的心跳（精度为96-99.75％）进行竞争性，并且可以通过融合多个节拍（从3到6个节拍的100％精度）进一步提高。此外，所提出的暹罗架构管理以将身份验证等错误率（eer）降低至1.29％。具有现实世界实验数据的Edith的有限案例研究还表明其作为实际认证系统的潜力。

心血管疾病是死亡率最严重的原因之一，每年在世界各地遭受沉重的生命。对血压的持续监测似乎是最可行的选择，但这需要一个侵入性的过程，带来了几层复杂性。这激发了我们开发一种通过使用光杀解功能图（PPG）信号的非侵入性方法来预测连续动脉血压（ABP）波形的方法。此外，我们探索了深度学习的优势，因为它可以通过使手工制作的功能计算无关紧要，这将使我们无法坚持理想形状的PPG信号，这是现有方法的缺点。因此，我们提出了一种基于深度学习的方法PPG2ABP，该方法可以从输入PPG信号中预测连续的ABP波形，平均绝对误差为4.604 mmHg，可保留一致的形状，大小和相位。但是，PPG2ABP的更惊人的成功事实证明，来自预测的ABP波形的DBP，MAP和SBP的计算值超过了几个指标下的现有作品，尽管没有明确培训PPG2ABP。

Pruning refers to the elimination of trivial weights from neural networks. The sub-networks within an overparameterized model produced after pruning are often called Lottery tickets. This research aims to generate winning lottery tickets from a set of lottery tickets that can achieve similar accuracy to the original unpruned network. We introduce a novel winning ticket called Cyclic Overlapping Lottery Ticket (COLT) by data splitting and cyclic retraining of the pruned network from scratch. We apply a cyclic pruning algorithm that keeps only the overlapping weights of different pruned models trained on different data segments. Our results demonstrate that COLT can achieve similar accuracies (obtained by the unpruned model) while maintaining high sparsities. We show that the accuracy of COLT is on par with the winning tickets of Lottery Ticket Hypothesis (LTH) and, at times, is better. Moreover, COLTs can be generated using fewer iterations than tickets generated by the popular Iterative Magnitude Pruning (IMP) method. In addition, we also notice COLTs generated on large datasets can be transferred to small ones without compromising performance, demonstrating its generalizing capability. We conduct all our experiments on Cifar-10, Cifar-100 & TinyImageNet datasets and report superior performance than the state-of-the-art methods.

In post-covid19 world, radio frequency (RF)-based non-contact methods, e.g., software-defined radios (SDR)-based methods have emerged as promising candidates for intelligent remote sensing of human vitals, and could help in containment of contagious viruses like covid19. To this end, this work utilizes the universal software radio peripherals (USRP)-based SDRs along with classical machine learning (ML) methods to design a non-contact method to monitor different breathing abnormalities. Under our proposed method, a subject rests his/her hand on a table in between the transmit and receive antennas, while an orthogonal frequency division multiplexing (OFDM) signal passes through the hand. Subsequently, the receiver extracts the channel frequency response (basically, fine-grained wireless channel state information), and feeds it to various ML algorithms which eventually classify between different breathing abnormalities. Among all classifiers, linear SVM classifier resulted in a maximum accuracy of 88.1\%. To train the ML classifiers in a supervised manner, data was collected by doing real-time experiments on 4 subjects in a lab environment. For label generation purpose, the breathing of the subjects was classified into three classes: normal, fast, and slow breathing. Furthermore, in addition to our proposed method (where only a hand is exposed to RF signals), we also implemented and tested the state-of-the-art method (where full chest is exposed to RF radiation). The performance comparison of the two methods reveals a trade-off, i.e., the accuracy of our proposed method is slightly inferior but our method results in minimal body exposure to RF radiation, compared to the benchmark method.

Accurate recognition of food items along with quality assessment is of paramount importance in the agricultural industry. Such automated systems can speed up the wheel of the food processing sector and save tons of manual labor. In this connection, the recent advancement of Deep learning-based architectures has introduced a wide variety of solutions offering remarkable performance in several classification tasks. In this work, we have exploited the concept of Densely Connected Convolutional Neural Networks (DenseNets) for fruit quality assessment. The feature propagation towards the deeper layers has enabled the network to tackle the vanishing gradient problems and ensured the reuse of features to learn meaningful insights. Evaluating on a dataset of 19,526 images containing six fruits having three quality grades for each, the proposed pipeline achieved a remarkable accuracy of 99.67%. The robustness of the model was further tested for fruit classification and quality assessment tasks where the model produced a similar performance, which makes it suitable for real-life applications.

In this paper, we assess the viability of transformer models in end-to-end InfoSec settings, in which no intermediate feature representations or processing steps occur outside the model. We implement transformer models for two distinct InfoSec data formats - specifically URLs and PE files - in a novel end-to-end approach, and explore a variety of architectural designs, training regimes, and experimental settings to determine the ingredients necessary for performant detection models. We show that in contrast to conventional transformers trained on more standard NLP-related tasks, our URL transformer model requires a different training approach to reach high performance levels. Specifically, we show that 1) pre-training on a massive corpus of unlabeled URL data for an auto-regressive task does not readily transfer to binary classification of malicious or benign URLs, but 2) that using an auxiliary auto-regressive loss improves performance when training from scratch. We introduce a method for mixed objective optimization, which dynamically balances contributions from both loss terms so that neither one of them dominates. We show that this method yields quantitative evaluation metrics comparable to that of several top-performing benchmark classifiers. Unlike URLs, binary executables contain longer and more distributed sequences of information-rich bytes. To accommodate such lengthy byte sequences, we introduce additional context length into the transformer by providing its self-attention layers with an adaptive span similar to Sukhbaatar et al. We demonstrate that this approach performs comparably to well-established malware detection models on benchmark PE file datasets, but also point out the need for further exploration into model improvements in scalability and compute efficiency.
