Abstract: A non-transitory computer readable storage medium with instructions executed by a processor maintains a collection of data access connectors configured to access different sources of unstructured data. A user interface with prompts for designating a selected data access connector from the data access connectors is supplied. Unstructured data is received from the selected data access connector. Numeric vectors characterizing the unstructured data are created from the unstructured data. The numeric vectors are stored and indexed.

Abstract: A non-transitory computer readable storage medium has instructions executed by a processor to maintain a repository of machine learning directed acyclic graphs. Each machine learning directed acyclic graph has machine learning artifacts as nodes and machine learning executors as edges joining machine learning artifacts. Each machine learning artifact has typed data that has associated conflict rules maintained by the repository. Each machine learning executor specifies executable code that executes a machine learning artifact as an input and produces a new machine learning artifact as an output. A request about an object in the repository is received. A response with information about the object is supplied.
