Systems and methods are described which relate to machine learning model validation. A first machine learning model may be trained to dependent variable data for a first population. A second machine learning model may be trained to simulate dependent variable data for the first population. The second machine learning model may then be applied to student activity data of a second population having different characteristics from the first population to produce simulated dependent variable data. The first machine learning model may then generate predictions for the second population, which may be validated via comparison to the simulated dependent variable data. A given simulated dependent variable value may be generated by the second machine learning model at a specific time T, where some features input to the machine learning model may be derived from datapoints occurring before Tand others being derived from datapoints occurring after T.

Systems and methods for validation of artificial intelligence models

Systems and methods of the present invention provide for storing textbook data, a glossary, and problems within a database; identifying a problem's guided solution, and a keyword within the solution matching an entry within the glossary, from which a skill tag is associated. The disclosed system then automatically generates an assessment including an assessment problem associated with the skill. If an incorrect response is received for the assessment problem, the database is updated to associate a user that input the response with the assessment problem and a skill. The system then automatically generates a customized exercise assignment associated in the database with the skill.
