  • Patent number: 11514321
    Abstract: Entity record pairs are extracted from a selected cluster of entity records. Attribute value pairs are obtained from the entity record pairs. Labels are assigned to the attribute value pairs based at least in part on entity-level similarity scores of the entity records from which the attribute value pairs were obtained. A machine learning model is trained, using a data set which includes at least some attribute value pairs to which the labels are assigned, to generate attribute similarity scores for pairs of attribute values.

  • Publication number: 20220342214
    Abstract: Techniques for artifact mitigation in an optical system are disclosed. Light associated with a world object is received at the optical system, which is characterized by a world side and a user side. Light associated with a virtual image is projected onto an eyepiece of the optical system, causing a portion of the light associated with the virtual image to propagate toward the user side and light associated with an artifact image to propagate toward the world side. A dimmer of the optical system positioned between the world side and the eyepiece is adjusted to reduce an intensity of the light associated with the artifact image impinging on the dimmer and an intensity of the light associated with the world object impinging on the dimmer.

  • Patent number: 11469101
    Abstract: Embodiments of the present application provide a semiconductor structure and a manufacturing method therefor. A buffer layer is disposed on a substrate layer, and the buffer layer includes a first buffer layer and a second buffer layer. By doping a transition metal in the first buffer layer, a deep level trap may be formed to capture background electrons, and diffusion of free electrons toward the substrate may also be avoided. By decreasing a doping concentration of the transition metal in the second buffer layer, a tailing effect is avoided and current collapse is prevented. By doping periodically the impurity in the buffer layer, the impurity may be as an acceptor impurity to compensate the background electrons, and then a concentration of the background electrons is reduced. By using the periodic doping method, dislocations, caused by doping, in the buffer layer may be effectively reduced.
