Output Files

OUTPUT FILE

• XXX_Prediction.csv :
  Currently, it is ordered by KC, student (and preserving the record order within a KC-student), which may not be the same as the original ordering in test set (unless you just have one HMM in test set).

  • actualLabel: actual student responses(correct or incorrect).
  • predLabel: predicted student responses.
  • predProbCorrect: predicted probability of getting correct responses.
  • priorProbKnown: predicted probability of known/mastered before updating by current observed correctness.
  • posteriorProbKnown: predicted probability of known/mastered after updating by current observed correctness (before doing transition to next hidden state).
  • student
  • kc: a skill.
  • problem
  • step

• XXX_Evaluation.csv :
  Evaluation files including:

  • predictive performance metrics on test set
  • plausibility metrics (see our EDM15 paper).
  • training information.

• XXX_Parameters.csv :
  This file maintains the HMM basic parameters and feature coefficients.

• Runtime.log :
  This file contains the basic runtime information (configuration, log likelihood changes, etc.).
