Provided is a system that includes at least one processor programmed or configured to receive an XML data file, wherein the XML data file includes data associated with one or more input parameters of a machine learning model, generate a code generation template based on the data associated with one or more input parameters of the machine learning model included in the XML file, where the code generation template includes one or more keys associated with one or more parameters of a transaction aggregate for an account of a user, and generate a file of executable code based on the code generation template, wherein the file of executable code includes instructions that, when executed by at least one processor, causes at least one processor to retrieve transaction aggregate data associated with the transaction aggregate for the account of the user. A method and computer program product are also provided.

System, method, and computer program product for generating code to retrieve aggregation data for machine learning models

A method for receiving text files, each having data defined in various format types. The text files are received without a reference to a schema defining the text files. A description file for each of the text files describing one of the format types is received and the description file includes a separate file from a corresponding text file. Before processing the text file and absent receiving the schema, the method identifies a data structure of the description file, the data structure comprising one or more parameters and definitions of the various format types. Each of the text files is processed and during processing of each of the text files, dynamically generating, at run-time, one or more reader engines to read the data in the text files and dynamically extracting, at run-time, data based on the identified data structure. The method generates an output file with the extracted data.
