The official implementation of "Edge-LLM: Enabling Efficient Large Language Model Adaptation on Edge Devices via Layerwise Unified Compression and Adaptive Layer Tuning and Voting".

Overview

We introduce a computation- and memory-efficient LLM tuning framework, called Edge-LLM, to facilitate affordable and effective LLM adaptation on edge devices. Specifically, Edge-LLM features three core components: (1) a layer-wise unified compression (LUC) technique to reduce the computation overhead by generating layer-wise pruning sparsity and quantization bit-width policies, (2) an adaptive layer tuning and voting scheme to reduce the memory overhead by reducing the backpropagation depth, and (3) a complementary hardware scheduling strategy to handle the irregular computation patterns introduced by LUC and adaptive layer tuning, thereby achieving efficient computation and data movements.

Installation

To run the code, please install the dependencies using

pip install -r requirements.txt 

Training and Evaluation

Layerwise Unified Compressed and Adaptive Layer Tuning

To launch the training of the whole Edge-LLM algorithm, please use the following command:

bash ./scripts/edge_llm_train.sh

We also provide the script to run each enablers of our proposed framework below

Quantize Model

In our implementation, we build our quantization mmethod on top of LLM-QAT. To try our proposed layer-wise pruning technique to prune the model, please use the following command to quantize and tune the model:

bash ./scripts/layer_wise_quantization.sh

Prune Model

In our implementation, we build our pruning method on top of SparseGPT. To only use our proposed layer-wise pruning technique to prune the model, please use the following command to prune and tune the model:

bash ./scripts/layer_wise_pruning.sh

Layerwise Unified Compressed Model

To test the model performance with only the layer-wise unified compression, please use the following command to compress and tune the model:

bash ./scripts/layer_wise_pruning_quantization.sh
