Adaptive Forgetting Curves for Spaced Repetition Language Learning
Table 1: Evaluation of forgetting curve models. Pimsleur and Leitner are previous methods of modelling the forgetting curve.
['Model', 'MAE↓']
By modifying the loss function to include complexity as a parameter in the C-HLR+ model, we considerably improved the performance of our model. This was in line with our hypothesis that more complex words are forgotten faster and thus are an important feature in modelling the forgetting curve.
