  • Publication number: 20200265074
    Abstract: An approach is provided for searching multilingual documents. A first classification is determined that includes a first document and other document(s) by minimizing a first distance between a first numerical fixed length vector for the first document and other numerical fixed length vector(s) for other document(s). Based on a query and a natural language detected in the query, a second document is selected. A second stream modeling the second document is encoded as a second numerical fixed length vector. Based on a distance between the first and second numerical fixed length vectors being less than a threshold, the first classification is identified as including the second document. Documents in the first classification are ranked and presented as having content matching the second document's content. At least one of the ranked documents is expressed in a natural language different from the natural language of the second document.

  • Patent number: 10748281
    Abstract: A method and system of detecting abnormalities captured in a medical image are provided. A medical image is received having one or more lesions and one or more interferences. One or more convolution layers are applied to the medical image to create one or more feature maps, respectively. A region proposal network (RPN) is applied to each of the one or more feature maps to create a bounding box around each lesion and interference. For each bounding box, an object in the bounding box is classified as a lesion, an interference, or a background. Each object that is incorrectly classified as a lesion but determined to be an interference, is stored as a hard-negative example to be part of a training set for a next application of the RPN.

  • Publication number: 20200260097
    Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes processing circuitry that can decode coded information of a transform block (TB) from a coded video bitstream. The coded information can indicate a region of the TB on which a secondary transform is applied. The region can include a first sub-region having transform coefficients calculated by the secondary transform and a second sub-region. The processing circuitry can determine, for a transform coefficient in the TB, whether a neighboring transform coefficient used to determine the transform coefficient is located in the second sub-region. When the neighboring transform coefficient is determined to be located in the second sub-region, the processing circuitry can determine the transform coefficient according to a default value for the neighboring transform coefficient and reconstruct a sample in the TB based on the transform coefficient for the sample.
