  • CONSTRAINED DECODING AND RANKING OF LANGUAGE MODELS FOR CODE GENERATION
    Publication number: 20230325154
    Abstract: In various embodiments, a process for constrained decoding and ranking of language models for code generation includes receiving a natural language input specifying a desired computer task. The process includes using a machine learning trained converter to convert the natural language input to an output in a computer language, including by, based on a specified grammar for the computer language, limiting eligible options for a token to include in the output in the computer language. The process includes providing the output in the computer language for computer execution.

  • Graph decomposition for fraudulent transaction analysis
    Patent number: 11636487
    Abstract: In an embodiment, a process for graph decomposition includes initializing nodes and edges of a data graph for analysis using a computer, and performing message passing between at least a portion of the nodes of the data graph to determine a corresponding measure of interest for each node of at least a portion of the data graph. The process further includes receiving an identification of one or more nodes of interest in the data graph, performing message passing between at least a portion of the nodes of the data graph using at least the determined measures of interest to identify a corresponding subgraph of interest for each of the one or more nodes of interest in the data graph, and performing an analysis action using the one or more identified subgraphs of interest.

  • Computer memory management during real-time fraudulent transaction analysis
    Patent number: 11062316
    Abstract: Computer memory management during real-time fraudulent transaction analysis is disclosed. In an embodiment, a method includes receiving a transaction entry and determining whether the transaction entry is potentially fraudulent, including by determining whether the transaction entry is correlated with another transaction entry in the computer memory or an already-identified suspicious pattern of other transaction entries. The method further includes determining whether to evict the transaction entry from the computer memory based on the determination of whether the transaction entry is potentially fraudulent. The method includes providing a result of fraudulent transaction analysis performed using the computer memory that has been optimized.
