In ear of smart cities, intelligent medical image recognition technique has become a promising way to solve remote patient diagnosis in IoMT. Although deep learning-based recognition approaches have received great development during the past decade, explainability always acts as a main obstacle to promote recognition approaches to higher levels. Because it is always hard to clearly grasp internal principles of deep learning models. In contrast, the conventional machine learning (CML)-based methods are well explainable, as they give relatively certain meanings to parameters. Motivated by the above view, this paper combines deep learning with the CML, and proposes a hybrid intelligence-driven medical image recognition framework in IoMT. On the one hand, the convolution neural network is utilized to extract deep and abstract features for initial images. On the other hand, the CML-based techniques are employed to reduce dimensions for extracted features and construct a strong classifier that output recognition results. A real dataset about pathologic myopia is selected to establish simulative scenario, in order to assess the proposed recognition framework. Results reveal that the proposal that improves recognition accuracy about two to three percent.
在智慧城市的背景下,智能医学图像识别技术已成为解决物联网医疗(IoMT)中远程患者诊断问题的一种很有前景的方法。尽管基于深度学习的识别方法在过去十年中取得了巨大发展,但可解释性一直是将识别方法提升到更高水平的主要障碍。因为总是很难清楚地掌握深度学习模型的内部原理。相比之下,基于传统机器学习(CML)的方法具有良好的可解释性,因为它们为参数赋予了相对明确的含义。受上述观点的启发,本文将深度学习与CML相结合,提出了一种物联网医疗中的混合智能驱动医学图像识别框架。一方面,利用卷积神经网络为初始图像提取深度和抽象特征。另一方面,采用基于CML的技术对提取的特征进行降维,并构建一个强大的分类器来输出识别结果。选择一个关于病理性近视的真实数据集来建立模拟场景,以评估所提出的识别框架。结果表明,该方案将识别准确率提高了约两到三个百分点。
