The combination of big data and deep learning is a world-shattering technology that can make a great impact on any industry if used in a proper way. With the availability of large volume of health care datasets and progressions in deep learning techniques, systems are now well equipped in diagnosing many health problems. Utilizing the intensity of substantial historical information in electronic health record (EHR), we built up, a conventional predictive temporal model utilizing recurrent neural systems (RNN) like LSTM and connected to longitudinal time stepped EHR. Experience records were contribution to RNN to anticipate the analysis and prescription classes for a resulting visit during heart disappointment (e.g. diagnosis codes, drug codes or method codes). In this paper, we also investigated whether use of deep learning to model temporal relations among events in electronic health records (EHRs) would enhance the model performance in predicting initial diagnosis of heart failure (HF) compared to some of the traditional methods that disregard temporality. By examining these time stamped EHRs, we could recognize the associations between various diagnosis occasions and finally predicate when a patient is being analyzed for a disease. In any case, it is hard to access the current EHR data straightforwardly, since almost all data are sparse and not standardized. Along these lines, we proposed a robust model for prediction of heart failure. The fundamental commitment of this paper is to predict the failure of heart by means of a neural network model based on patient's electronic medicinal information. In order to, demonstrate the diagnosis events and prediction of heart failure, we used the medical concept vectors and the essential standards of a long short-term memory (LSTM) deep network model. The proposed LSTM model uses SiLU and tanh as activation function in the hidden layers and Softmax in output layer in the network. Bridgeout is used as a regularization technique for weight optimization throughout the network. Assessments subject to the real-time data exhibit the favorable effectiveness and feasibility of recommended model in the risk of heart failure prediction. The results showed improved accuracy in heart failure detection and the model performance is compared using the existing deep learning models. Enhanced prior detection could expose novel chances for deferring or anticipating movement to analysis of heart failure and diminish cost.
大数据和深度学习的结合是一项具有颠覆性的技术,如果使用得当,可以对任何行业产生重大影响。随着大量医疗保健数据集的可用性和深度学习技术的进步,现在系统已经能够很好地诊断许多健康问题。利用电子健康记录(EHR)中的大量历史信息强度,我们构建了一个利用递归神经网络(RNN)(如 LSTM)的传统预测时间模型,并将其连接到纵向时间步 EHR。经验记录被贡献给 RNN,以预测心力衰竭(例如诊断代码、药物代码或方法代码)就诊期间的分析和处方类别。在本文中,我们还研究了使用深度学习对电子健康记录(EHR)中的事件之间的时间关系进行建模是否会提高模型在预测心力衰竭(HF)初始诊断方面的性能,与一些忽略时间性的传统方法相比。通过检查这些带有时间戳的 EHR,我们可以识别各种诊断事件之间的关联,最终预测患者何时正在接受疾病分析。无论如何,直接访问当前的 EHR 数据是很困难的,因为几乎所有数据都是稀疏的,而且没有标准化。因此,我们提出了一种用于预测心力衰竭的稳健模型。本文的基本目标是通过基于患者电子医疗信息的神经网络模型来预测心力衰竭的失败。为了演示心力衰竭的诊断事件和预测,我们使用了医疗概念向量和长短期记忆(LSTM)深度网络模型的基本标准。所提出的 LSTM 模型在网络的隐藏层中使用 SiLU 和 tanh 作为激活函数,在输出层中使用 Softmax。Bridgeout 被用作整个网络中权重优化的正则化技术。基于实时数据的评估展示了所建议模型在心力衰竭预测风险中的良好有效性和可行性。结果表明,心力衰竭检测的准确性得到了提高,并且使用现有的深度学习模型对模型性能进行了比较。提前检测可以为推迟或预测心力衰竭分析的机会提供新的机会,并降低成本。
