  • COMPUTER-READABLE RECORDING MEDIUM, ABNORMALITY DETERMINATION METHOD, AND ABNORMALITY DETERMINATION DEVICE
    Publication number: 20200074281
    Abstract: A learning device performs learning by an autoencoder, using waveform data with changes over time that is obtained from an intrinsic movement of an object. The learning device performs persistent homology conversion to calculate a change in the number of connected component according to a threshold change in a value direction for the waveform data. The learning device determines abnormality based on a determination result of a learner to which output data of the autoencoder obtained from the waveform data and output data obtained from the persistent homology conversion are input, and in which machine learning about abnormality of the waveform data has been performed.

  • Computing of a resulting closed triangulated polyhedral surface from a first and a second modeled objects
    Patent number: 8854367
    Abstract: The invention is directed to a computer-implemented process, in a computer-aided geometric design system, for computing a resulting closed triangulated polyhedral surface from a first and a second modeled objects. The first modeled object is modeled by a first closed triangulated polyhedral surface and the second modeled object is modeled by a second closed triangulated polyhedral surface.
