可信的研究环境(TRE)S是安全和安全的环境,其中研究人员可以访问敏感数据。随着电子健康记录(EHR),医学成像和基因组数据等医疗数据的增长和多样性,通常在使用人工智能(AI)和机器学习子场(ML)的使用增加医疗领域。这产生了披露从TRES的新类型输出的希望,例如培训的机器学习模型。虽然特定的指导方针和政策存在于TRES中的统计披露控制,但它们并不令人满意地涵盖这些新类型的输出请求。在本文中,我们定义了在TRES内医疗保健机器学习的应用程序和披露的一些挑战。我们描述了各种漏洞,引入AI带来了TRES。我们还提供了与培训ML模型的披露相关的不同类型和风险水平的介绍。我们终于描述了开发和调整政策和工具的新研究机会,以安全地披露从TRES的机器学习输出。

This paper utilizes an anomaly detection algorithm to check if underwater gliders are operating normally in the unknown ocean environment. Glider pilots can be warned of the detected glider anomaly in real time, thus taking over the glider appropriately and avoiding further damage to the glider. The adopted algorithm is validated by two valuable sets of data in real glider deployments, the University of South Florida (USF) glider Stella and the Skidaway Institute of Oceanography (SkIO) glider Angus.

Objective. The impact of social determinants of health (SDoH) on patients' healthcare quality and the disparity is well-known. Many SDoH items are not coded in structured forms in electronic health records. These items are often captured in free-text clinical notes, but there are limited methods for automatically extracting them. We explore a multi-stage pipeline involving named entity recognition (NER), relation classification (RC), and text classification methods to extract SDoH information from clinical notes automatically. Materials and Methods. The study uses the N2C2 Shared Task data, which was collected from two sources of clinical notes: MIMIC-III and University of Washington Harborview Medical Centers. It contains 4480 social history sections with full annotation for twelve SDoHs. In order to handle the issue of overlapping entities, we developed a novel marker-based NER model. We used it in a multi-stage pipeline to extract SDoH information from clinical notes. Results. Our marker-based system outperformed the state-of-the-art span-based models at handling overlapping entities based on the overall Micro-F1 score performance. It also achieved state-of-the-art performance compared to the shared task methods. Conclusion. The major finding of this study is that the multi-stage pipeline effectively extracts SDoH information from clinical notes. This approach can potentially improve the understanding and tracking of SDoHs in clinical settings. However, error propagation may be an issue, and further research is needed to improve the extraction of entities with complex semantic meanings and low-resource entities using external knowledge.

Most research studying social determinants of health (SDoH) has focused on physician notes or structured elements of the electronic medical record (EMR). We hypothesize that clinical notes from social workers, whose role is to ameliorate social and economic factors, might provide a richer source of data on SDoH. We sought to perform topic modeling to identify robust topics of discussion within a large cohort of social work notes. We retrieved a diverse, deidentified corpus of 0.95 million clinical social work notes from 181,644 patients at the University of California, San Francisco. We used word frequency analysis and Latent Dirichlet Allocation (LDA) topic modeling analysis to characterize this corpus and identify potential topics of discussion. Word frequency analysis identified both medical and non-medical terms associated with specific ICD10 chapters. The LDA topic modeling analysis extracted 11 topics related to social determinants of health risk factors including financial status, abuse history, social support, risk of death, and mental health. In addition, the topic modeling approach captured the variation between different types of social work notes and across patients with different types of diseases or conditions. We demonstrated that social work notes contain rich, unique, and otherwise unobtainable information on an individual's SDoH.

The International Workshop on Reading Music Systems (WoRMS) is a workshop that tries to connect researchers who develop systems for reading music, such as in the field of Optical Music Recognition, with other researchers and practitioners that could benefit from such systems, like librarians or musicologists. The relevant topics of interest for the workshop include, but are not limited to: Music reading systems; Optical music recognition; Datasets and performance evaluation; Image processing on music scores; Writer identification; Authoring, editing, storing and presentation systems for music scores; Multi-modal systems; Novel input-methods for music to produce written music; Web-based Music Information Retrieval services; Applications and projects; Use-cases related to written music. These are the proceedings of the 3rd International Workshop on Reading Music Systems, held in Alicante on the 23rd of July 2021.

We summarize our TRECVID 2022 Ad-hoc Video Search (AVS) experiments. Our solution is built with two new techniques, namely Lightweight Attentional Feature Fusion (LAFF) for combining diverse visual / textual features and Bidirectional Negation Learning (BNL) for addressing queries that contain negation cues. In particular, LAFF performs feature fusion at both early and late stages and at both text and video ends to exploit diverse (off-the-shelf) features. Compared to multi-head self attention, LAFF is much more compact yet more effective. Its attentional weights can also be used for selecting fewer features, with the retrieval performance mostly preserved. BNL trains a negation-aware video retrieval model by minimizing a bidirectionally constrained loss per triplet, where a triplet consists of a given training video, its original description and a partially negated description. For video feature extraction, we use pre-trained CLIP, BLIP, BEiT, ResNeXt-101 and irCSN. As for text features, we adopt bag-of-words, word2vec, CLIP and BLIP. Our training data consists of MSR-VTT, TGIF and VATEX that were used in our previous participation. In addition, we automatically caption the V3C1 collection for pre-training. The 2022 edition of the TRECVID benchmark has again been a fruitful participation for the RUCMM team. Our best run, with an infAP of 0.262, is ranked at the second place teamwise.

机械系统自然地在描述其固有对称性的主束上演变。随之而来的配置歧管分解为对称组和内部形状空间,为许多机器人和生物系统的运动提供了深刻的见解。另一方面,差异平坦的属性已实现了各种机器人系统的有效,有效的计划和控制算法。然而,为任意机器人系统找到平坦输出的实际手段仍然是一个悬而未决的问题。在这项工作中,我们在这两个域之间展示了令人惊讶的新连接,这是首次使用对称性直接使用对称性来构建平面输出。我们为捆绑包的琐碎化提供了足够的条件,其中组变量本身是平坦的输出。我们将其称为几何扁平输出,因为它是均衡的(即保持对称性的),并且通常是全局或几乎全球的,因此通常不受其他平坦输出不享受的属性。在这样的琐碎化中,很容易解决运动计划问题,因为组变量的给定轨迹将充分确定精确实现此运动的形状变量的轨迹。我们为机器人系统提供了部分目录,该目录具有几何扁平输出,并为平面火箭,平面空中操纵器和四极管提供了示例。

Teleperation已成为全自动系统,以实现人类机器人的人体水平能力的替代解决方案。具体而言,全身控制的远程运行是指挥类人动物的有前途的无提手术策略,但需要更多的身体和心理努力。为了减轻这一限制,研究人员提出了共享控制方法,结合了机器人决策,以帮助人类完成低级任务,从而进一步减少了运营工作。然而,尚未探索用于全身级别的人型类人形端粒体的共享控制方法。在这项工作中,我们研究了全身反馈如何影响不同环境中不同共享控制方法的性能。提出了时间衍生的Sigmoid功能(TDSF),以产生障碍物的更直观的力反馈。进行了全面的人类实验,结果得出的结论是,力反馈增强了在不熟悉的环境中的全身端粒化表现,但可以在熟悉的环境中降低性能。通过触觉传达机器人的意图显示出进一步的改进,因为操作员可以将力反馈用于短途计划和视觉反馈进行长距离计划。
