Setups

The requiring environment is as bellow:

• Linux
• Python 3+
• PyTorch 1.2.0
• Scikit-learn 0.21.3
• Scipy 1.3.1
• Numpy 1.17.2

Running AKT.

Here are some examples for using AKT-Rasch model (on ASSISTments2009 and ASSISTments2017 datasets):

python main.py --dataset assist2009_pid --model akt_pid 
python main.py --dataset assist2017_pid --model akt_pid 

Here is an example for using AKT-NonRasch model (on all datasets):

python3 main.py --dataset assist2015 --model akt_cid

Errata

Thanks to Rui Zou and Xuhao Li for pointing out a bug in line 306 of akt.py. It has been fixed now.
