  • Patent number: 11947633
    Abstract: One or more computing devices, systems, and/or methods for oversampling for imbalanced test data are provided. A classifier is configured to classify data points as either belonging to a first class or a second class. A determination may be made that the first class and the second class are imbalanced where a first number of data points estimated to be part of the first class is a threshold amount less than a second number of data points estimated to be part of the second class. An oversampling ratio is determined for the first class. The oversampling ratio is used to select a sample set of data points for editorial labeling, where the sampling set of data points comprises a total number of data points below a threshold amount.

  • Patent number: 9532449
    Abstract: A double-sided patterned transparent conductive film includes an upper surface conductive layer (12) and a lower surface conductive layer (12). The upper surface conductive layer is a patterned trench network; the lower surface conductive layer is a full-surface trench network. A trench of the upper surface conductive layer is filled with conductive material (13), and a trench of the lower surface conductive layer is intermittently filled with conductive material (13). The double-sided patterned transparent conductive film has a high resolution, transmittance, independently adjustable square resistance and many other advantages, such that the transparent conductive film saves a cost of PET. According to the manufacturing method, the alignment is not needed for double-sided imprinting of a single flexible substrate, thus the process is simple, low cost, advantageous for industrial production.
