Healthcare and academic entities, as well as companies, use machine learning in order to develop personalised, preventive, predictive and participatory medicine, including medical tools. For example, ML is used for drug repurposing or digital pathology (analysis of pathology slide images). In research performed in Israel, a deep learning algorithm trained on a linked data set of mammograms and electronic health records was found to be able to assess breast cancer at a level comparable to radiologists and to have the potential to substantially reduce missed diagnoses of breast cancer.
