Neural network-based assessment engine for the determination of a knowledge state

A system comprising:

• a memory to store instructions associated with a neural network model;
• and
• a processing device, operatively coupled to the memory, to execute the instructions associated with the neural network model to perform operations comprising:
• determining an initial knowledge state of a student relating to a subject;
• generating a vector representation of a set of items associated with the subject;
• executing, by the neural network model, an assessment comprising at least a portion of the set of items relating to the subject;
• providing a first item of the set of items to the student;
• receiving, from the student, a first response to the first item;
• generating an updated vector representation based on the first response to the first item;
• and
• generating, based on the updated vector representation and the initial knowledge state, a first set of probabilities associated with an updated knowledge state of the student corresponding to the set of items relating to the subject.

A non-transitory computer readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• determining, by a neural network model executed by the processing device, an initial knowledge state of a student relating to a subject;
• generating a vector representation of a set of items associated with the subject;
• executing, by the neural network model, an assessment comprising at least a portion of the set of items relating to the subject;
• providing a first item of the set of items to the student;
• receiving, from the student, a first response to the first item;
• generating an updated vector representation based on the first response to the first item;
• and
• generating, based on the updated vector representation and the initial knowledge state, a first set of probabilities associated with an updated knowledge state of the student corresponding to the set of items relating to the subject.
