Recent advances in technology have immensely increased available computing power and data storage capacity . At the same time, digitisation of previously analog aspects of business and life, has made vast amounts of data available for analysis. Every digital log entry can somehow be collected and analysed. This is the ideal breeding ground for machine learning!
The deep learning model used in the app has been trained on a few thousand x-ray images contained in the following dataset: Kermany Daniel, Zhang Kang, Goldbaum Michael (2018). Labeled Optical Coherence Tomography (OCT) and Chest X-Ray Images for Classification. Mendeley Data, v2, http://dx.doi.org/10.17632/rscbjbr9sj.2. The 2-layer convolutional neural network achieved accuracy exceeding 86% on the relevant test set of more than 500 x-rays. However, as mentioned below there are multiple limitations in the predictive power of the deep learning model. This model has not been clinically validated and thus it cannot be trusted for any kind of clinical use! Researchers may be interested to try the model’s accuracy.
