Machine learning for the identification of molecular conformationsWe can overcome the information gap by acquiring large amounts of data while manipulating the molecule a small region around its current conformation. As long as this manipulation is fully reversible, the conformation is essentially not changed. We will implement machine learning solutions (such as (un)supervised learning, kernel ridge regression, support vector machines etc.) for the various data analysis tasks required in this context. Supervised machine learning which, based on wavelet analysis, detects discontinuities in the experimental signals that indicate (irreversible) conformational relaxations. Unsupervised machine learning to structure small segments of experimental data into larger units. Acquiring large amounts of simulation data using a reliable and accurate molecular mechanics model. Supervised machine learning (support vector machine) to determine the shape of the region within which manipulation is reversible for experimental and simulated data. Kernel regression to interpolate measured and simulated data in each region. An algorithm to assign experimental regions to simulated ones on a bipartite graph via measurements of manifold distances. This creates a map of all possible manipulation processes.
