How to run

Experiment 1

python main.py --lr=0.1 --num_epoch=10 --opt=sgd --err_type=strict --model_type=original

Experiment 2

python main.py --lr=0.1 --num_epoch=10 --opt=sgd --err_type=fixed_pred --num_iter=5 --model_type=original --eta=1

Experiment 3

python main.py --lr=0.001 --num_epoch=5 --opt=adam --err_type=fixed_pred --num_iter=20 --model_type=modified --train_batch_size=1000 --test_batch_size=1000 

For other options, take a look at main.py file.
