Recent years witnessed the breakthrough of face recognition with deep convolutional neural networks. Dozens of papers in the field of FR are published every year. Some of them were applied in the industrial community and played an important role in human life such as device unlock, mobile payment, and so on. This paper provides an introduction to face recognition, including its history, pipeline, algorithms based on conventional manually designed features or deep learning, mainstream training, evaluation datasets, and related applications. We have analyzed and compared state-of-the-art works as many as possible, and also carefully designed a set of experiments to find the effect of backbone size and data distribution. This survey is a material of the tutorial named The Practical Face Recognition Technology in the Industrial World in the FG2023.

Objective: We aim to develop an open-source natural language processing (NLP) package, SODA (i.e., SOcial DeterminAnts), with pre-trained transformer models to extract social determinants of health (SDoH) for cancer patients, examine the generalizability of SODA to a new disease domain (i.e., opioid use), and evaluate the extraction rate of SDoH using cancer populations. Methods: We identified SDoH categories and attributes and developed an SDoH corpus using clinical notes from a general cancer cohort. We compared four transformer-based NLP models to extract SDoH, examined the generalizability of NLP models to a cohort of patients prescribed with opioids, and explored customization strategies to improve performance. We applied the best NLP model to extract 19 categories of SDoH from the breast (n=7,971), lung (n=11,804), and colorectal cancer (n=6,240) cohorts. Results and Conclusion: We developed a corpus of 629 cancer patients notes with annotations of 13,193 SDoH concepts/attributes from 19 categories of SDoH. The Bidirectional Encoder Representations from Transformers (BERT) model achieved the best strict/lenient F1 scores of 0.9216 and 0.9441 for SDoH concept extraction, 0.9617 and 0.9626 for linking attributes to SDoH concepts. Fine-tuning the NLP models using new annotations from opioid use patients improved the strict/lenient F1 scores from 0.8172/0.8502 to 0.8312/0.8679. The extraction rates among 19 categories of SDoH varied greatly, where 10 SDoH could be extracted from >70% of cancer patients, but 9 SDoH had a low extraction rate (<70% of cancer patients). The SODA package with pre-trained transformer models is publicly available at https://github.com/uf-hobiinformatics-lab/SDoH_SODA.

The task of response selection in multi-turn dialogue is to find the best option from all candidates. In order to improve the reasoning ability of the model, previous studies pay more attention to using explicit algorithms to model the dependencies between utterances, which are deterministic, limited and inflexible. In addition, few studies consider differences between the options before and after reasoning. In this paper, we propose an Implicit Relational Reasoning Graph Network to address these issues, which consists of the Utterance Relational Reasoner (URR) and the Option Dual Comparator (ODC). URR aims to implicitly extract dependencies between utterances, as well as utterances and options, and make reasoning with relational graph convolutional networks. ODC focuses on perceiving the difference between the options through dual comparison, which can eliminate the interference of the noise options. Experimental results on two multi-turn dialogue reasoning benchmark datasets MuTual and MuTual+ show that our method significantly improves the baseline of four pretrained language models and achieves state-of-the-art performance. The model surpasses human performance for the first time on the MuTual dataset.

Compared with model-based control and optimization methods, reinforcement learning (RL) provides a data-driven, learning-based framework to formulate and solve sequential decision-making problems. The RL framework has become promising due to largely improved data availability and computing power in the aviation industry. Many aviation-based applications can be formulated or treated as sequential decision-making problems. Some of them are offline planning problems, while others need to be solved online and are safety-critical. In this survey paper, we first describe standard RL formulations and solutions. Then we survey the landscape of existing RL-based applications in aviation. Finally, we summarize the paper, identify the technical gaps, and suggest future directions of RL research in aviation.

二进制神经网络(BNNS)对现实世界中嵌入式设备显示出巨大的希望。作为实现强大BNN的关键步骤之一,规模因子计算在减少其实价对应物的性能差距方面起着至关重要的作用。然而,现有的BNN忽略了实价重量和尺度因子的固有双线关系,从而导致训练过程不足引起的亚最佳模型。为了解决这个问题,提出了复发性双线性优化,以通过将固有的双线性变量关联到背面传播过程中,以改善BNNS(RBONN)的学习过程。我们的工作是从双线性角度优化BNN的首次尝试。具体而言,我们采用经常​​性优化和密度 - 列表来依次回溯稀疏的实价过滤器,该过滤器将经过充分的训练并基于可控的学习过程达到其性能限制。我们获得了强大的rbonn,在各种模型和数据集上的最先进的BNN上表现出令人印象深刻的性能。特别是,在对象检测的任务下,rbonn具有出色的概括性能。我们的代码在https://github.com/stevetsui/rbonn上进行开源。

无监督的域适应性(UDA)是最小化域间隙的方法。生成方法是最小化航空图像域间隙的常见方法,可改善下游任务的性能,例如跨域语义分割。对于航空图像,数字表面模型(DSM)通常在源域和目标域中可用。DSM中的深度信息将外部信息带入生成模型。但是,很少有研究利用它。在本文中,提出了深度辅助残留物(DRDG),其中使用深度监督损失(DSL)和深度周期一致性损失(DCCL)将深度信息带入生成模型。实验结果表明,DRDG在跨域语义分割任务中达到生成方法之间达到最新的精度。

我们考虑了自主渠道访问(AutoCA)的问题,其中一组终端试图以分布式方式通过常见的无线通道发现具有访问点(AP)的通信策略。由于拓扑不规则和终端的通信范围有限,因此对AutoCA的实用挑战是隐藏的终端问题,在无线网络中臭名昭著,可以使吞吐量和延迟性能恶化。为了应对挑战,本文提出了一种新的多代理深钢筋学习范式,该学习范式被称为Madrl-HT,在存在隐藏码头的情况下为Autoca量身定制。 MADRL-HT利用拓扑见解,并将每个终端的观察空间转变为独立于终端数量的可扩展形式。为了补偿部分可观察性,我们提出了一种外观机制,以便终端可以从载体感知的通道状态以及AP的反馈中推断出其隐藏终端的行为。提出了基于窗口的全球奖励功能,从而指示终端在学习过程中平衡终端的传输机会,以最大程度地提高系统吞吐量。广泛的数值实验验证了我们的解决方案基准测试的优越性能,并通过避免碰撞(CSMA/CA)方案对旧的载体 - 义值访问。

旨在找到合成靶分子的反应途径的循环合成计划在化学和药物发现中起着重要作用。此任务通常被建模为搜索问题。最近,数据驱动的方法吸引了许多研究兴趣,并显示了反递归计划的有希望的结果。我们观察到在搜索过程中多次访问了相同的中间分子,并且通常在先前基于树的方法(例如,或树搜索,蒙特卡洛树搜索)中独立处理。这样的裁员使搜索过程效率低下。我们提出了基于图的搜索策略,以消除任何中间分子的冗余探索。由于图形上的搜索比在树上更复杂,因此我们进一步采用图形神经网络来指导图形搜索。同时,我们的方法可以在图中搜索一批目标,并在基于树的搜索方法中删除目标间重复。两个数据集的实验结果证明了我们方法的有效性。尤其是在广泛使用的USPTO基准测试中,我们将搜索成功率提高到99.47%,以2.6分提高了先前的最新性能。

使用深度学习方法(DL)方法的结核病(TB)自动分割(TB) - 一致的病变(CXR)可以帮助减少放射科医生的努力,补充临床决策,并有可能改善患者治疗。文献中的大多数作品使用粗边界框注释讨论培训自动分割模型。但是,边界框注释的粒度可能导致在像素级别上包含相当一部分假阳性和负面因素,从而可能对整体语义分割性能产生不利影响。这项研究(i)评估了使用TB一致性病变的细粒注释和(ii)U-NET模型变体的培训和构造的好处CXR。我们使用多种集合方法(例如位和位或位,位 - 最大值和堆叠)评估了分割性能。我们观察到,与单个组成模型和其他集合方法相比,堆叠合奏表现出优异的分割性能(骰子得分:0.5743,95%置信区间:(0.4055,0.7431))。据我们所知,这是第一个应用合奏学习来改善细粒度元素一致性病变细分性能的研究。
