    肺部疾病是世界上常见的异常。肺部疾病包括肺结核,气胸,心脏肥大,肺不张,肺炎,等。肺部疾病的及时预后至关重要。深度学习(DL)技术的进步对医学领域产生了重大影响并做出了贡献,特别是在利用医学成像进行分析方面,预后,和临床医生的治疗决策。用于放射学的许多当代DL策略关注于利用成像特征的数据的单一模态,而不考虑为临床一致的预后决策提供更有价值的补充信息的临床背景。此外,在多模态异构数据上执行机器学习(ML)或DL操作时,选择最佳数据融合策略至关重要。我们研究了利用DL技术从异质放射学胸部X射线(CXR)和临床文本报告中预测肺部异常的多模式医学融合策略。在这项研究中,我们从CXR和临床报告提出了两种有效的单峰和多模态子网络来预测肺异常.我们进行了全面的分析,并比较了单峰和多峰模型的性能。将所提出的模型应用于标准增强数据和生成的合成数据,以检查模型从新的和看不见的数据进行预测的能力。根据公开的印第安纳大学数据集和从私人医院收集的数据,对提出的模型进行了全面评估和检查。与单峰模型相比,所提出的多峰模型具有出色的结果。
    Pulmonary disease is a commonly occurring abnormality throughout this world. The pulmonary diseases include Tuberculosis, Pneumothorax, Cardiomegaly, Pulmonary atelectasis, Pneumonia, etc. A timely prognosis of pulmonary disease is essential. Increasing progress in Deep Learning (DL) techniques has significantly impacted and contributed to the medical domain, specifically in leveraging medical imaging for analysis, prognosis, and therapeutic decisions for clinicians. Many contemporary DL strategies for radiology focus on a single modality of data utilizing imaging features without considering the clinical context that provides more valuable complementary information for clinically consistent prognostic decisions. Also, the selection of the best data fusion strategy is crucial when performing Machine Learning (ML) or DL operation on multimodal heterogeneous data. We investigated multimodal medical fusion strategies leveraging DL techniques to predict pulmonary abnormality from the heterogeneous radiology Chest X-Rays (CXRs) and clinical text reports. In this research, we have proposed two effective unimodal and multimodal subnetworks to predict pulmonary abnormality from the CXR and clinical reports. We have conducted a comprehensive analysis and compared the performance of unimodal and multimodal models. The proposed models were applied to standard augmented data and the synthetic data generated to check the model\'s ability to predict from the new and unseen data. The proposed models were thoroughly assessed and examined against the publicly available Indiana university dataset and the data collected from the private medical hospital. The proposed multimodal models have given superior results compared to the unimodal models.

    蚊子监测数据可用于预测与人类疾病相关的蚊子分布和动态。这些数据通常由独立机构收集,并汇总到州和国家一级的门户网站,以表征广泛的空间和时间动态。这些较大的存储库还可以共享用于蚊子和/或疾病预测和预测模型的数据。假设,但并不总是得到证实,是各机构数据的一致性。报告中的细微差异对于预测模型的开发和最终解释可能很重要。使用来自亚利桑那州的蚊媒监测数据作为案例研究,我们发现各机构在诱捕行为的报告方式上存在差异.如果用户仅粗略熟悉蚊子监测数据,则报告中的不一致可能会干扰定量比较。如果它们在元数据中是明确的,则可以克服一些不一致,而如果它们在如何记录数据方面没有改变,则其他不一致可能产生有偏差的估计。建模者和矢量控制机构之间共享元数据和协作对于提高估计质量是必要的。努力改善共享,显示,比较来自多个机构的矢量数据正在进行中,但必须谨慎使用现有数据。
    Mosquito surveillance data can be used for predicting mosquito distribution and dynamics as they relate to human disease. Often these data are collected by independent agencies and aggregated to state and national level portals to characterize broad spatial and temporal dynamics. These larger repositories may also share the data for use in mosquito and/or disease prediction and forecasting models. Assumed, but not always confirmed, is consistency of data across agencies. Subtle differences in reporting may be important for development and the eventual interpretation of predictive models. Using mosquito vector surveillance data from Arizona as a case study, we found differences among agencies in how trapping practices were reported. Inconsistencies in reporting may interfere with quantitative comparisons if the user has only cursory familiarity with mosquito surveillance data. Some inconsistencies can be overcome if they are explicit in the metadata while others may yield biased estimates if they are not changed in how data are recorded. Sharing of metadata and collaboration between modelers and vector control agencies is necessary for improving the quality of the estimations. Efforts to improve sharing, displaying, and comparing vector data from multiple agencies are underway, but existing data must be used with caution.
