Quick Start

conda env create igpruning python=3.10

git clone https://github.com/ictnlp/IG-Pruning.git
cd IG-Pruning
pip install -r requirements.txt

Mask Candidate Discovery

A semantic clustering-based mask discovery stage that identifies diverse, high-quality mask candidates while capturing global information through rapidly converging trainable masks.

bash scripts/main_result/sample_cluster.sh

Dynamic Routing at Inference

A lightweight inference-time routing mechanism that requires no additional training of the base model parameters, enabling efficient dynamic adaptation to varying inputs.

bash scripts/main_result/sample_cluster.sh

Evaluation

To evaluate the performace, we use lm-evaluation-harness.

bash scripts/main_result/eval_mask.sh
