BAIM enriches knowledge tracing item representations by deriving stage-level embeddings from Polya's four problem-solving stages and routing them adaptively per learner context, yielding consistent gains over pretraining baselines on two datasets.
The projec- tion network consists of a linear transformation Linear(4Dinput →D kt) followed by ReLU activa- tion and dropout
