Latest Patents

One of Zappella's latest patents is titled "Semantic coherence analysis of deep neural networks." This patent discloses methods and apparatus for interpreting a deep neural network (DNN) using a Semantic Coherence Analysis (SCA)-based interpretation technique. In this invention, a multi-layered DNN trained for one task is analyzed using the SCA technique to select a layer that produces salient features for another task. The DNN layers are tested with samples labeled with a set of concept labels, and the output features are gathered and analyzed according to these concepts. The output is scored with a semantic coherence score, indicating how well the layer separates the concepts. A layer is selected based on its semantic coherence score, and in some embodiments, a support vector machine (SVM) or additional neural network may be added to generate classification results.

Another notable patent is the "Data retrieval system." This system allows users to select different aspects of data objects to match with similar aspects of other data objects. A user inputs a search data object and a value, and a neural network computes features for the search object at multiple layers corresponding to different aspects. A descriptor is generated for the search object from features output at a specific layer position determined by the value. The descriptor is then compared to corresponding descriptors for objects in a collection to select those that include similar aspects. This innovative approach enables users to explore different aspects of an object to find related objects.
