InsCD, namely Instant Cognitive Diagnosis (Chinese: 时诊), is a highly modularized python library for cognitive diagnosis in intelligent education systems. This library incorporates both traditional methods (e.g., solving IRT via statistics) and deep learning-based methods (e.g., modelling students and exercises via graph neural networks).

📰 News

• [2024.8.31] InsCD toolkit v1.2 is released. What's New: We implement two new models: symbolic cognitive diagnosis model (SymbolCD) and hypergraph cognitive diagnosis model (HyperCD)
• [2024.7.14] InsCD toolkit v1.1 is released and available for downloading.
• [2024.4.20] InsCD toolkit v1.0 is released.

🚀 Getting Started

Installation

Git and install with pip:

git clone https://github.com/ECNU-ILOG/InsCD.git
cd <path of code>
pip install .

or install the library from pypi

pip install inscdkit==1.3.1

⚠️ Note: Installing DGL

InsCD depends on DGL (Deep Graph Library). The installation of DGL varies depending on your operating system, PyTorch version, and whether you are using a GPU.

Please refer to the official DGL installation guide and choose the command that matches your environment:

Quick Example

The following code is a simple example of cognitive diagnosis implemented by inscd. We load build-in datasets, create cognitive diagnosis model, train model and show its performance:

inscd_run --model NCDM --datahub_name Math1

If you want to use multi-GPU parallel training, please use the following command-line:

accelerate launch -m inscd_run --model NCDM --datahub_name Math1

For other optional parameters, please use the format --[key]=[value].

🛠 Implementation

We incoporate classical, famous and state-of-the-art methods published or accepted by leading journals and conferences in the field of psychometric, machine learning and data mining. The reason why we call this toolkit "modulaized" is that we not only provide the "model", but also divide the model into two parts (i.e., extractor and interaction function), which enables us to design new models (e.g., extractor of Hypergraph with interaction function of KaNCD). To evaluate the model, we also provide vairous open-source datasets in online or offline scenarios.

🤔 Frequent Asked Questions

Problem: Why can't I download datasets when using built-in dataset classes (e.g., NeurIPS20 in inscd.datahub)?

Since these datasets are saved in the Google Driver, they may be not available in some countries and regions. You can use proxy and add the following commands in your terminal:

export http_proxy = 'http://<IP address of proxy>:<Port of proxy>'
export https_proxy = 'http://<IP address of proxy>:<Port of proxy>'
export all_proxy = 'socks5://<IP address of proxy>:<Port of proxy>'

Problem: WandB fails to connect or hangs due to network issues?

You can disable WandB's network usage by setting the following environment variable:

export WANDB_MODE=offline

💡 Note: These settings are only effective for the current terminal session.
