GMOCAT-CODE

Official Code for paper "GMOCAT: A Graph-Enhanced Multi-Objective Method for Computerized Adaptive Testing" (KDD 2023)

requirements:

Python, PyTorch, dgl

how to run codes

We have provided the preprocessed dataset assist2009 so that we can directly run experiments on IRT with assist2009. To run GMOCAT, please run train_gcat.sh.

how to run codes from scratch

1. put raw data in raw_data/.
2. run preprocessing.py and construct_graphs.py.
3. run pretrain.sh.
4. run the selection algorithms train_gcat.sh.
