  • Publication number: 20210056355
    Abstract: In an embodiment, a method for generating contrastive information for a classifier prediction comprises receiving image data representative of an input image, using a deep learning classifier model to predict a first classification for the input image, evaluating the input image using a plurality of classifier functions corresponding to respective high-level features to identify one or more of the high-level features absent from the input image, and identifying, from among the high-level features absent from the input image, a pertinent-negative feature that, if added to the input image, will result in the deep learning classifier model predicting a second classification for the modified input image, the second classification being different from the first classification. In an embodiment, the method includes creating a pertinent-positive image that is a modified version of the input image that has the first classification and fewer than all superpixels of the input image.

  • Publication number: 20200226459
    Abstract: A processor receives input data and provides the input data to a first neural network including a first neural network model. The first neural network model has a first numerical precision level. A first feature vector is generated from the input data using the first neural network. The input data is provided to a second neural network including a second neural network model. The second neural network model has a second numerical precision level different from the first numerical precession level. A second feature vector is generated from the input data using the second neural network. A difference metric is computed between the first feature vector and the second feature vector. The difference metric is indicative of whether the input data includes adversarial data.

    Abstract: The multiple winding inductor assembly includes a first core piece, a second core piece, a first conductor, and a first core assembly. The first core assembly includes a third core piece and a second conductor. The first and second conductors, together with the first, second, and third core pieces, form multiple inductors that, when working individually, do not cause mutual inductance on those not at work, thereby avoiding energy consumption. In addition, the inductor assembly may be extended in only one direction when cascading more inductors, facilitating circuit design and layout, and the configuration of the inductor assembly on the circuit board.
