The code is heavily based on Rosinality's PyTorch implementation of StyleGAN2.
All experiments are conducted at 128x128 resolution.
To train the Decoupled AE-StyleGAN, we use the following training procedure:
python train_aegan.py \
--path data/ffhq \
--sample_cache data/sample_ffhq128_64.npy \
--which_latent w_plus \
--lambda_rec_w 0 \
--iter 200000 \
--size 128 \
--name ffhq_aegan_wplus_decoupled \
--log_every 500 \
--save_every 2000 \
--eval_every 2000 \
--dataset imagefolder \
--inception inception_ffhq128.pkl \
--n_sample_fid 10000 \
--decouple_d \
--lambda_rec_d 0 \
--g_reg_every 0 \
--batch 16 \
--lr 0.0025 \
--r1 0.2048 \
--ema_kimg 5 \
--which_metric fid_sample fid_recon --use_adaptive_weight --disc_iter_start 30000
To train the Joint AE-StyleGAN, we use the following training procedure:
python train_aegan.py \
--path data/ffhq \
--sample_cache data/sample_ffhq128_64.npy \
--iter 200000 \
--size 128 \
--name ffhq_aegan_wplus_joint \
--which_latent w_plus \
--lambda_rec_w 0 \
--log_every 500 \
--save_every 2000 \
--eval_every 2000 \
--dataset imagefolder \
--inception inception_ffhq128.pkl \
--n_sample_fid 10000 \
--lambda_rec_d 0.1 \
--lambda_fake_d 0.9 \
--lambda_fake_g 0.9 \
--joint \ # joint train G with D
--g_reg_every 0 \
--batch 16 \
--lr 0.0025 \
--r1 0.2048 \
--ema_kimg 5 \
--which_metric fid_sample fid_recon --use_adaptive_weight --disc_iter_start 30000
To train a StyleGAN2 (without R1 regularization), we use the following training procedure:
python train.py \
--path data/ffhq \
--iter 200000 \
--size 128 \
--name ffhq_gan \
--log_every 500 \
--save_every 2000 \
--eval_every 2000 \
--dataset imagefolder \
--inception inception_ffhq128.pkl \
--n_sample_fid 10000 \
--g_reg_every 0 \
--batch 16 \
--lr 0.0025 \
--r1 0.2048 \
--ema_kimg 5
To train a (reimplemented) Style-ALAE model, use the following command:
python train_alae.py \
--path data/ffhq \
--sample_cache data/sample_ffhq128_64.npy \
--iter 200000 \
--size 128 \
--name ffhq_alae_wtied_recw=1_mlpd=4 \
--which_latent w_tied \
--which_phi_e lin1 \
--n_mlp_d 4 \
--log_every 500 \
--save_every 2000 \
--eval_every 2000 \
--dataset imagefolder \
--inception inception_ffhq128.pkl \
--n_sample_fid 10000 \
--lambda_rec_w 1 \
--lambda_fake_d 1 \
--lambda_fake_g 1 \
--lambda_rec_d 0 \
--lambda_pix 0 \
--lambda_vgg 0 \
--lambda_adv 0 \
--g_reg_every 0 \
--batch 16 \
--lr 0.0025 \
--r1 0.2048 \
--ema_kimg 5 \
--which_metric fid_sample fid_recon
