Description

Large-scale log data from the Mnemosyne flashcard software, used by the article to compare memory models. After filtering, the authors select a random subset that "contains 859 , 591 interactions, 2, 742 users, and 88 , 892 items". Each interaction carries a self-reported 0-5 grade, which the authors discretize into binary recall, and models are compared by ten-fold cross-validated AUC and a held-out test set.

Design Implications

Context

Requirements

• Filtering out users and items with fewer than five interactions.
• Discretizing self-reported grades into binary recall outcomes and scaling review intervals to days.

Constraints

Target Learners

• Users of the Mnemosyne flashcard software

Target Learning Goals

• Validating memory models of recall as a function of reinforcement and delay

Claims

• In Mnemosyne flashcard log data, adding a delay term improves the recall-prediction performance of exponential forgetting curve memory models. [+W]
• In Mnemosyne log data, exponential forgetting curve models that include a delay term perform comparably to 1PL-IRT, the best-performing benchmark model. [+W]
• In Mnemosyne log data, item-specific difficulty parameters outperform a global difficulty for lower and higher Leitner decks, while global difficulty performs better for intermediate decks. [+W]
• In Mnemosyne log data, setting memory strength equal to an item's Leitner deck position predicts recall better than number of past reviews, which beats constant strength. [+W]
