[paper]

Overview

1. Installation

• Ubuntu 18.04.5 LTS
• CUDA 11.3
• Python 3.6.12
• pytorch == 1.10.1

2. Dataset

• Idiap Replay Attack [paper]
• OULU-NPU [paper]
• CASIA-MFSD [paper]
• MSU-MFSD [paper]

Data pre-processing: Follow the preprocessing steps in SAFAS.

3. Training

3.1 Running

Our implementaion of GAC-FAS is in optimizers/gacfas.py

Update configuration file and start training ICM2O by:

python train.py --config ./configs/ICM2O.yaml

Pre-trained weights are released.

3.2 Bag of tricks

Please consider following parameters while runing as it affects on final results (See our Suppl.)

• Random seed
• Leaning rate decay steps (40, 5)
• FC learning rate scale (1, 10)
• Logit scale (12, 16, 32)
• Weight decay (1e-4, 5e-4, 6e-4)
• ERM losses (BCE, CE: OMI2C)
• Color Jitter may help
• Balanced live vs. spoof data loader may help (only for OCI2M)
• Larger lr may help (1e-2: OMI2C)
