Data Integration, cross-modality, evidence synthesis, Machine Learning in medicine
the figure below shows a variety of plots from different papers on deep learning (see at the bottom) focusing on data integration. Data integration is essential to extract all the information, including causality, about a certain subject.
(Various Deep Learning Approaches for data integration: arXiv:1909.06442; arXiv:1907.05628; arXiv:1905.08721; arXiv:1905.06515; arXiv:1905.00534; arXiv:1904.06316; Medical Imaging 2019: Image Processing 10949, 109491L; arXiv:1901.03906; arXiv:1901.03419; BioRxiv, 801605; arXiv:1809.10341; International Conference on Theory and Application of Diagrams, 390-398; Bioinformatics 34 (17), 2944-2950; Nature communications 8 (1), 2045)
Methods Integration: relationship between computational modeling and machine learningThe figure below shows on the right, examples of modeling techniques ( a computational/mathematical model is a representation of the essential aspects of an existing system (or a system to be constructed) which presents knowledge of that system in usable form' (Eykhoff, 1974). On the left there are methodologies, implemented in software, to analyse Big data, showing the ability to automatically learn and improve from experience without being explicitly programmed. At the bottom some relevant publications from the group.
