Quick Start

We provide Math1 as sample datasets to validate the HyperCDM. You can reproduce the results by directly running main.py, i.e.

python main.py

Run with other datasets

Step 1. prepare dataset

Refer to the sample dataset, you should prepare the following files:

├─dataset
│  └─Your_dataset
│          config.json
│          data.csv   
│          q.csv

Specifically, config.json records all necessary settings of dataset like the number of students, and the format of config.json is shown as following:

{
  "dataset": [String, the name of the dataset],
  "q_file": [string, the relative path of Q matrix],
  "data": [string, the relative path of response logs],
  "student_num": [int, the number of students],
  "exercise_num": [int, the number of exercises],
  "knowledge_num": [int, the number of knowledge concepts]
}

data.csv consists of response logs in the following format:

[int, student_id1],[int, question_id1],[0/1, response to question_id1]
[int, student_id1],[int, question_id2],[0/1, response to question_id2]
...
[int, student_idn],[int, question_idm],[0/1, response to question_idm]

q.csv contains the relevant between questions and knowledge attributes. Each entry in the $i$-th row and the $j$-th column means whether the $i$-th question involves the $j$-th knowledge attributes.

Step 2. coding

Refer to the main.py, you can change the path to different configuration file.

Step 3. run code

python main.py
