Gaudi-DASH

This repository contains the implementation of Direction-Aware SHrinking (DASH), a method for warm-starting neural network training without losing plasticity under stationary conditions in Intel Gaudi.

---

We also included code in verify.ipynb and verify_nvidia.ipynb that reports some issues encountered when applying the Sharpness-Aware Minimization (SAM) algorithm in eager/lazy mode with Intel Gaudi.

🛠️ Setup

To set up the environment, run:

conda env create -f env.yaml

🚀 Usage

Standard Training

To train the model, use:

python main.py --dataset [dataset] --model [model] --train_type [train_type] --optimizer_type [optimizer_type]

Available options:

• Datasets: cifar10, cifar100, svhn, imagenet
• Models: resnet18, vgg16, mlp
• Training types: cold, warm, warm_rm, reset, l2_init, sp, dash
• Optimizer types: sgd, sam

State-of-the-Art (SoTA) Training

For SoTA settings, use:

python main.py --dataset [dataset] --model resnet18 --train_type [train_type] --optimizer_type [optimizer_type] \
    --sota True --weight_decay 5e-4 --learning_rate 0.1 --batch_size 128 --max_epoch 260

Available options for SoTA settings:

• Datasets: cifar10, cifar100, imagenet
• Model: resnet18
• Training types and optimizer types: Same as standard training

Tiny-ImageNet Training

To use dataset = imagenet:

1. Download the dataset from http://cs231n.stanford.edu/tiny-imagenet-200.zip or use wget:

wget http://cs231n.stanford.edu/tiny-imagenet-200.zip

2. Create a folder named data:

mkdir data

3. Unzip the downloaded Tiny-ImageNet dataset to the data folder

unzip tiny-imagenet-200.zip -d data/

4. Launch tiny-imagenet_preprocess.py to preprocess the test data:

python tiny-imagenet_preprocess.py

📈 Synthetic Experiment

For our synthetic experiment described in Section 4, please refer to the Discrete_Feature_Learning.ipynb file.
