Abstract: Embodiments of the present invention provide an approach for applying cognitive diagnostic modeling (CDM) and deep learning algorithms to improve knowledge transfer (KT) progress. Specifically, the approach aims to improve the process of transferring knowledge by breaking down a learning task into smaller subtasks that are related to a specific learning goal. The provided responses for each subtask are then evaluated using a deep learning algorithm, which generates a continuous score based on the difference between the provided response and the expected response. Each continuous score is then converted into a binary value to obtain a set of binary values. Based on the set of binary values, a diagnostic report is generated that reflects the progress of knowledge transfer for the assigned learning task. This approach allows for a more detailed and accurate assessment of the learning process, which can help to identify areas where further improvement is needed.
