  • Patent number: 11961281
    Abstract: Techniques for training a machine-learning model are described. In an example, a computer generates a first pseudo-label indicating a first mask associated with a first object detected by a first machine-learning model in a first training image. A transformed image of the first training image can be generated using a transformation. Based on the transformation, a second pseudo-label indicating a second mask detected in the transformed image and corresponding to the first mask can be determined. A second machine-learning model can be trained using the second pseudo-label. The trained, second machine-learning model can detect a third mask associated with a second object based on a second image.

  • Patent number: 11845969
    Abstract: The present invention relates to a process of converting carbon dioxide using a combination of a carbon dioxide mineralization and the metabolism of sulfur-oxidizing microorganisms. According to the process, a carbonate produced in the carbon dioxide mineralization reaction can be converted to a useful substance without supplying an external additional energy source (light, electrical energy, etc.) and mineral resources (metal ions). In addition, the process can be continuously performed by recycling metal ions necessary for the carbon dioxide mineralization reaction.
