论文摘要
肺部疾病在世界各地很常见。其中包括慢性阻塞性肺部疾病,肺炎,哮喘,结核病,纤维化等。及时诊断为肺部疾病。为此,已经开发了许多图像处理和机器学习模型。现有的深度学习技术的不同形式,包括卷积神经网络(CNN),香草神经网络,基于视觉几何组的神经网络(VGG)和胶囊网络,用于肺部疾病预测。基本CNN的旋转,倾斜度或其他异常图像方向的基本CNN的性能较差。因此,我们通过将VGG,数据增强和空间变压器网络(STN)与CNN相结合,提出了一个新的混合深度学习框架。这种新的混合方法在这里称为具有CNN(VDSNET)的VGG数据STN。作为实现工具,使用了Jupyter笔记本,TensorFlow和Keras。新模型应用于从Kaggle存储库收集的NIH胸部X射线图像数据集。考虑了数据集的完整和示例版本。对于完整数据集和示例数据集,VDSNET根据许多指标,包括精度,召回,F0.5分数和验证精度,均优于现有方法。对于完整数据集的情况,VDSNET的验证精度为73%,而Vanilla Grey,Vanilla RGB,Hybrid CNN和VGG以及修改后的胶囊网络的精度分别为67.8%,69%,69.5%,69.5%,60.5%和63.8%。当使用示例数据集而不是完整数据集时,VDSNET需要较低的培训时间,而付出了较低的验证精度。因此,拟议的VDSNET框架将简化专家和医生对肺部疾病的检测。
Lung disease is common throughout the world. These include chronic obstructive pulmonary disease, pneumonia, asthma, tuberculosis, fibrosis, etc. Timely diagnosis of lung disease is essential. Many image processing and machine learning models have been developed for this purpose. Different forms of existing deep learning techniques including convolutional neural network (CNN), vanilla neural network, visual geometry group based neural network (VGG), and capsule network are applied for lung disease prediction.The basic CNN has poor performance for rotated, tilted, or other abnormal image orientation. Therefore, we propose a new hybrid deep learning framework by combining VGG, data augmentation and spatial transformer network (STN) with CNN. This new hybrid method is termed here as VGG Data STN with CNN (VDSNet). As implementation tools, Jupyter Notebook, Tensorflow, and Keras are used. The new model is applied to NIH chest X-ray image dataset collected from Kaggle repository. Full and sample versions of the dataset are considered. For both full and sample datasets, VDSNet outperforms existing methods in terms of a number of metrics including precision, recall, F0.5 score and validation accuracy. For the case of full dataset, VDSNet exhibits a validation accuracy of 73%, while vanilla gray, vanilla RGB, hybrid CNN and VGG, and modified capsule network have accuracy values of 67.8%, 69%, 69.5%, 60.5% and 63.8%, respectively. When sample dataset rather than full dataset is used, VDSNet requires much lower training time at the expense of a slightly lower validation accuracy. Hence, the proposed VDSNet framework will simplify the detection of lung disease for experts as well as for doctors.
