This repo contains the scripts used to perform the experiments in this blog post. If you're using this code or our results, please cite it appropriately.
You will find
- a script to train cifar10 to >94% accuracy in 30 epochs without Test Time Augmentation or 18 with.
- a script to finetune a pretrained resnet50 on the Standford cars dataset to 90% accuracy in 60 epochs.
- a script to train an AWD LSTM (or QRNN) to the same perplexity as the Saleforce team that created them but in just 90 epochs.
- the fastai library is necessary to run all the models. If you didn't pip-install it, don't forget to have a simlink pointing to it in the directory where you clone this repo.
- pytorch 0.4.0 is necessary to have the implementation of amsgrad inside Adam.
- additonaly, the QRNNs model requires the cupy library.
Run the script get_data.sh that will download and organize the data needed for the models
- this should train cifar10 to 94.25% accuracy (on average):
python train_cifar10.py 3e-3 --wd=0.1 --wd_loss=False
- this should train cifar10 to 94% accuracy (on average) but faster:
python train_cifar10.py 3e-3 --wd=0.1 --wd_loss=False --cyc_len=18 --tta=True
- this should get 90% accuracy (on average) without TTA, 91% with:
python fit_stanford_cars.py '(1e-2,3e-3)' --wd=1e-3 --tta=True
- this should train an AWD LSTM to 68.7/65.5 perplexity without cache pointer, 52.9/50.9 with
python train_rnn.py 5e-3 --wd=1.2e-6 --alpha=3 --beta=1.5
- this should train an AWD QRNN to 69.6/66.7 perplexity without cache pointer, 53.6/51.7 with
python train_rnn.py 5e-3 --wd=1e-6 --qrnn=True
