Abstract Scope An approach called “virtual screening” uses a machine-learning technique to estimate the target property. After screening the whole library, verification process is required to examine the predictive power of the model. Models can be improved iteratively through Bayesian optimization process. The virtual screening is useful when real screening is not practical, i.e. when the production cost for the descriptors is too high to cover the whole library within the practical time. This is the same if one needs to explore too large space to cover exhaustively. Discovery of new low lattice-thermal-conductivity (LTC) crystals through the virtual screening technique will be shown as an example. We have established our own dataset of LTC computed by the first principles anharmonic force constant method as implemented in phonopy, an open source package for first principles phonon calculations. Candidates found by the virtual screening are validated by first principles LTC calculations.
