  • Patent number: 12182212
    Abstract: The present disclosure relates to a method and an apparatus, an electronic device and a storage medium for web search. The method includes: acquiring a steady-state visual evoked potential in EEG information, where the steady-state visual evoked potential is generated when a user gazes at a key on a query inputting keyboard in a visual spelling page; sending the steady-state visual evoked potential to a server, such that the server, based on the steady-state visual evoked potential, determines a character string inputted by the user, and a landing page corresponding to the character string; and in response to receiving the landing page sent by the server, displaying the landing page.

  • Patent number: 11323717
    Abstract: The present disclosure relates to encoding and decoding video by employing texture coding. In particular, a texture region is identified within a video picture and a texture patch is determined for the texture region. Moreover, a first set of parameters is derived specifying weighting factors for reconstructing spectral coefficients of the texture region by fitting the texture region in a spectral domain to a first function of the texture patch, the first function being defined by the first set of parameters. The texture patch and the first set of parameters are then included into a bitstream which is output by an encoder and provided in this way to the decoder which reconstructs the texture based on the patch and the function applied to the patch.

    Abstract: The present disclosure relates to encoding a decoding video employing texture coding. In particular, a texture region is identified within a video picture and a texture patch is determined for said region. Moreover, a set of parameters specifies luminance within the texture region (1001) by fitting the texture region samples to a two-dimensional polynomial function of the patch determined according to the set of parameters (1040); and/or motion within the texture region by fitting motion estimated between the texture region of the video picture and an adjacent picture to a two-dimensional polynomial The texture patch and the first set of parameters are then included into a bitstream which is output of the encoder and provided in this way to the decoder which reconstructs the texture based on the patch and the function applied to the patch.

  • Patent number: 10872303
    Abstract: In an example embodiment, a confidential data architecture is extended by providing components for reliably inferring confidential data insights (e.g., median salary) for cohorts with little or no actual submitted confidential data. This is performed by inferring confidential data values based on organizations that are considered to be peers to the organization of interest. This solution involves two parts: the generation of a novel, semantic representation (embedding) of organizations to be used to compute a similarity measure between any two organizations, and the use of the semantic representation to compute a peer organization group of a given company.

  • Publication number: 20200304797
    Abstract: A texture region is identified within a video picture, and a texture patch is determined for the region. Clustering is performed to identify a texture region within the video image. The clustering is further refined. In particular, one or more brightness parameters of a polynomial is determined by fitting the polynomial to the identified texture region. In the identified texture region, samples are detected with a distance to the fitted polynomial exceeding a first threshold. A refined texture region is identified as the texture region excluding one or more of the detected samples. The refined texture region is encoded separately from portions of the video image not belonging to the refined texture region.

  • Publication number: 20190129995
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for expanding search queries. A search system identifies, based on search parameters received from a client device, a target company identified in the search parameters. The search parameters include a search term comprising at least two keywords, a first one of the at least two keyword identifying the target company, and the second one of the at least two keywords identifying an employment position. The search system identifies a second company based on a set of peer scores indicating a probability of employees transitioning between companies. The peer scores are calculated based on historical movement data indicating employee transitions between companies. The search system generates an expanded search term comprising a new keyword identifying the second company and the second keyword identifying the employment position.
