Pytorch Implementation of A Pyramid Architecture of GANs

---

This is a pytorch implementation for reproducing PAGAN results in the paper Learning Face Age Progression: A Pyramid Architecture of GANs.

Please note that this is not the official code and The code may still have errors for the results did not reach the original results in the paper.😩

Requirements

---

• Pytorch 1.0
• Python 3.6
• Visdom 0.1.8
• Pillow 6.0

Dataset

---

• CACD
• FGnet

Please pay attention to splitting CACD_dataset to train_dataset & val_dataset. and after make_label.py , move dataset to the path likedata_train/young(or elder1,elder2,elder3,val,test).

Pretrained Models

---

You can download pretrained vgg-face models from (http://www.robots.ox.ac.uk/~albanie/pytorch-models.html) and refer to this paper (https://arxiv.org/ftp/arxiv/papers/1709/1709.01664.pdf) to train age estimation networks, then move the two models to ./model_vgg.

It will require about 1.1 GB of disk space.

Running Models

---

you can run the shell script train.sh and test.sh.

Please note that modifying the path in the CONFIG when different age cluster.

Results

Here are some visualization results. And age estimation & face verification results by using face++ API.

• train:

  • age_cluster_1:
