Machine learning "red dot": open-source, cloud, deep convolutional neural networks in chest radiograph binary normality classification. - PubMed - NCBI

To develop a machine learning-based model for the binary classification of chest radiography abnormalities, to serve as a retrospective tool in guiding clinician reporting prioritisation. The open-source machine learning library, Tensorflow, was used to retrain a final layer of the deep convolutional neural network, Inception, to perform binary normality classification on two, anonymised, public image datasets. Re-training was performed on 47,644 images using commodity hardware, with validation testing on 5,505 previously unseen radiographs. Confusion matrix analysis was performed to derive diagnostic utility metrics. This study demonstrates the application of a machine learning-based approach to classify chest radiographs as normal or abnormal.
