Publication number: 20230135401Abstract: In an example, a particular type of deep learning model is used in the global model of the GDMix model: a Factorization Machine. A Factorization Machine combines a Support Vector Machine (SVM) and Matrix Factorizations. It has the advantage of modeling data with huge sparsity well, while maintaining a linear time complexity. A modification may be further made to the Factorization Machine by introducing L2 norm reduction. This acts to divide calculations made by the Factorization Machine into a portion that can be precomputed and a portion that cannot be precomputed. The portion that can be precomputed is then precomputed in an offline manner. As such, when the model is operated in an online manner, the Factorization Machine only needs to compute the portion that cannot be precomputed, reducing the number of operations that need to performed at runtime and greatly improving processing speed over prior machine learned models.Type: ApplicationFiled: October 28, 2021Publication date: May 4, 2023Inventors: Qiang Xiao, Haichao Wei, Jun Shi, Huiji Gao

Publication number: 20220318499Abstract: Computer-implemented machine learning-based techniques for assisted electronic message composition in a vertical messaging context. The vertical messaging context may be any electronic messaging context in which senders repetitively compose electronic messages to send to recipients where the messages are not identical but nonetheless have common tone, sentiment, content, and structure. The techniques assist users that compose electronic messages in a particular vertical messaging context in composing those messages quickly, with few or no grammatical errors, and with a likelihood of being positively received by the recipients of the messages.Type: ApplicationFiled: March 31, 2021Publication date: October 6, 2022Inventors: Qiang XIAO, Haichao WEI, Praveen Kumar BODIGUTLA, Huiji GAO, Arya G.

Patent number: 11314792Abstract: Systems and methods are provided for digital assistant configuration and functionality. For example, systems and methods provide for receiving a query from a user via a computing device, processing language in the query to identify a plurality of elements associated with the query, and analyzing the plurality of elements associated with the query to determine an intent of the query by mapping the plurality of elements associated with the query to a list of predetermined intents by comparing the plurality of elements associated with the query to each intent in the list of predetermined intents to generate a score for each intent in the list of predetermined intents. Systems and methods further provide for determining a subset of the predetermined intents based on the score for each intent in the list of predetermined intents, and providing recommendations related to the query based on the subset of predetermined intents.Type: GrantFiled: March 15, 2017Date of Patent: April 26, 2022Assignee: SAP SEInventors: Priyanka Khaitan, Haichao Wei, Kevin Hsu, Mitchell Clark

Patent number: 11170058Abstract: In an example, one or more tokens in a freeform search query are identified, each token corresponding to a search term or combination of neighboring search terms in the freeform search query. A graph structure and flat data corresponding to the graph structure are obtained. A search for results relevant to the identified one or more tokens is performed using a first search process, the first search process using the graph structure and flat data to rank search results according to a first ranking order and populate a why found table. Pieces of data corresponding to the results relevant to the identified one or more tokens are joined using the why found table, forming a view and one or more patterns of operators and terms, in a pattern database, matching the one or more operators and one or more surrounding terms in the freeform search query are found.Type: GrantFiled: December 19, 2019Date of Patent: November 9, 2021Assignee: SAP SEInventors: Haichao Wei, Priyanka Khaitan

Patent number: 10726072Abstract: In an example, data in a non-flat format and metadata corresponding to the data are obtained from a first database. The data is flattened into flat data and augmented with the metadata. One or more pieces of the flat data are scanned to locate a first piece of flat data having a first attribute with attribute values that are a subset of attribute values of a second attribute of a second piece of flat data. A link is then created between the first attribute of the first piece of flat data and the second attribute of the second piece of flat data. A graph structure is generated, the graph structure containing a plurality of nodes, each node corresponding to a data type of the flat data and corresponding to one or more pieces of data in the flat data of the corresponding data type.Type: GrantFiled: January 25, 2018Date of Patent: July 28, 2020Assignee: SAP SEInventors: Haichao Wei, Priyanka Khaitan

Patent number: 10713310Abstract: In an example, a graph structure and flat data corresponding to the graph structure are obtained, the graph structure containing a plurality of nodes. Stop words are removed from one or more search terms to obtain modified search terms. For each of the modified search terms, the pieces of data from the flat data are searched to locate one or more matching pieces of data from the flat data, wherein a piece of data from the flat data matches if it contains at least one attribute with a value that is similar to the modified search term. This information is used to calculate fuzzy match scores for each matching piece of data from the flat data.Type: GrantFiled: January 25, 2018Date of Patent: July 14, 2020Assignee: SAP SE WalldorfInventors: Haichao Wei, Priyanka Khaitan
