Medical internet of things leads to revolutionary improvements in medical services, also known as smart healthcare. With the big healthcare data, data mining and machine learning can assist wellness management and intelligent diagnosis, and achieve the P4-medicine. However, healthcare data has high sparsity and heterogeneity. In this paper, we propose a Heterogeneous Transferring Prediction System (HTPS). Feature engineering mechanism transforms the dataset into sparse and dense feature matrices, and autoencoders in the embedding networks not only embed features but also transfer knowledge from heterogeneous datasets. Experimental results show that the proposed HTPS outperforms the benchmark systems on various prediction tasks and datasets, and ablation studies present the effectiveness of each designed mechanism. Experimental results demonstrate the negative impact of heterogeneous data on benchmark systems and the high transferability of the proposed HTPS.

医疗物联网带来了医疗服务的革命性进步,被称为智能医疗。通过大型医疗数据,数据挖掘和机器学习可以辅助健康管理和智能诊断,实现P4-medicine。然而,医疗数据有很高的稀疏性和异构性。本文提出了一种基于异构转移学习的预测系统,即 Heterogeneous Transferring Prediction System(HTPS)。特征工程机制将数据集转换为稀疏和密集的特征矩阵,嵌入网络中的自编码器不仅嵌入特征,还从异构数据集中转移知识。实验结果表明,所提出的 HTPS 在各种预测任务和数据集上优于基准系统,拆分研究展示了每个设计机制的有效性。实验结果展示了异构数据对基准系统的负面影响和所提出的 HTPS 的高转移能力。
