Concept

Dataset (Using deep reinforcement learning for personalizing review sessions on e-learning platforms with spaced repetition)

In this research synthetic dataset was used. The simulators: Half-Life Regression (HLR), GPL (General-Power Law) , Exponential Forgetting Curve (EFC) were used to generate the data. The data had following representation: {q, a, t, d}:

  1. q - most recent item shown to the student
  2. a - [0, 1] incorrect/correct answer
  3. t - timestamp
  4. d - delay between most recent item and before (Set to 5s)

For LSTM the data was generated by EFC. The data was generated in 3 different ways:

  1. Random Sample: exercises and answers by students were randomly collected
  2. Random Policy Tutor: the exercises were chosen by the policy at random while student answer weren't
  3. Supermemo Tutor: Supermemo algorithm was used
