  • Publication number: 20220351090
    Abstract: Disclosed is a federated learning method for decision tree-oriented horizontal. The method comprises the following steps: all participants searching for a quantile sketch of each feature in a data feature set based on dichotomy; the participants constructing a local histogram for each feature by using locally held data features according to the quantile sketch; adding noise satisfying differential privacy to all local histograms, and sending the local histograms to a coordinator after processing through the secure aggregation method; the coordinator merging the local histograms of each feature into a global histogram, and training a root node of a first decision tree according to the histogram; the coordinator sending information of the node to other participants; and all participants updating the local histograms and repeating the above process for training to obtain the trained decision trees.

  • Patent number: 11488551
    Abstract: To increase the spatial resolution of a liquid crystal display (LCD) device, instead of emitting colors of an image (e.g., the three primary colors) in a single frame, the colors of an image are emitted sequentially. For example, if the colors of the image are red, blue, and green, the colors are emitted sequentially at a rate three times the desired frame rate of the display. The colors are emitted from a backlight unit (BLU) that produces pulses of colored light successively. By emitting colors sequentially, the number of subpixels in a pixel can be decreased or eliminated. Thus, among other advantages, the size of each pixel can decrease and the spatial resolution of the display device (e.g., pixels per inch) can increase.
