Eureka-Moments in Transformers:
Multi-Step Tasks Reveal Softmax Induced Optimization Problems

This is the code accompanying our ICML 2024 paper Eureka-Moments in Transformers: Multi-Step Tasks Reveal Softmax Induced Optimization Problems.

Examples of Eureka-Moments.

Installation

We recommend using anaconda to set up the environment. Run

conda create -n eureka python=3.9
conda activate eureka

conda install pytorch==1.12.1 torchvision==0.13.1 -c pytorch
conda install matplotlib
conda install conda-forge::tensorboard
conda install tensorboardx
conda install conda-forge::python-dateutil
pip install timm==0.4.12
pip install "Pillow<10.0.0"

to create and activate your conda environment.

Download FashionMnist and MNIST and place them in the data folder

Using the code

To train a vanilla ViT on our main dataset use

python main.py --lr=5e-4 --min-lr=1e-6 --mnist_task spacial_decision_indicator_digit_1_2_fashion --data-set MNIST_spacial_decision --output_dir <your_out_path> 

To train a ViT with NormSoftmax on our main dataset use

python main.py --lr=1e-5 --min-lr=1e-6 --mnist_task spacial_decision_indicator_digit_1_2_fashion --data-set MNIST_spacial_decision --attention_type=norm_softmax --output_dir <your_out_path> 

To train a ViT with HT on our main dataset use

python main.py --lr=1e-4 --min-lr=1e-6 --mnist_task spacial_decision_indicator_digit_1_2_fashion --data-set MNIST_spacial_decision --temperature_annealing=True --start_temperature=3.0 --end_temperature=0.125 --temperature_schedule='half_cosine' --output_dir <your_out_path> 

To log gradients and attention maps use also

--return_attention=True --qkv_grad_plot=True --log_attention=True --log_abs_gradient=True
