Model identification and Q-matrix incremental inference in cognitive diagnosis
作者：
Highlights：
• Joint estimate the Q matrix, item parameters and attribute-mastery-pattern.
• Online estimate the Q matrix, item parameters and attribute-mastery-pattern.
• The modified online estimation algorithm can further improve the recover ratio.
• The algorithms can recover the true Q matrix based on a good or a bad input.
• Relative to the original method, the revised algorithms can be more likely to use.
