Abstract
A method includes receiving interaction data including more than one interaction type and providing the interaction data to a first machine learning model to generate a vector representation defining similarity measures between subsets of the interaction data and update a knowledge graph. The method includes retrieving data associated with a user based on a target associated with a prediction associated with a capability level the user and providing inputs to multiple machine learning models to define relative complexity scores, pseudoguessing weights, and an item discrimination index, which are provided to a transformer trained on the knowledge graph to generate at least one prediction. The method includes providing the at least one prediction to a machine learning model to generate a plurality of simulations. The method includes identifying, based on the plurality of simulations, a prediction associated with a capability level of the user.
