Face recognition model training

Model training: In the paper, we employ MS1MV2 as the training dataset which can be downloaded from InsightFace (MS1M-ArcFace in DataZoo) Download MS1MV2 dataset from insightface on strictly follow the licence distribution

Unzip the dataset and place it in the data folder

Rename the config/config_xxxxxx.py to config/config.py

1. Train PocketNet with ArcFace loss
   • ./train.sh
2. Train PocketNet with template knowledge distillation
   • ./train_kd.sh
3. Train PocketNet with multi-step template knowledge distillation
   • ./train_kd.sh

Model	Parameters (M)	configuration	log	pretrained model
PocketNetS-128	0.92	Config	log	Pretrained-model
PocketNetS-256	0.99	Config	log	Pretrained-model
PocketNetM-128	1.68	Config	log	Pretrained-model
PocketNetM-256	1.75	Config	log	Pretrained-model

All code has been trained and tested using Pytorch 1.7.1

Face recognition evaluation

evaluation on LFW, AgeDb-30, CPLFW, CALFW and CFP-FP:

1. download the data from their offical webpages.
2. alternative: The evaluation datasets are available in the training dataset package as bin file
3. Rename the configuration file in config directory based on the evaluation model e.g. rename config_PocketNetM128.py to config.py to evaluate the PocketNetM128
4. set the config.rec to dataset folder e.g. data/faces_emore
5. set the config.val_targets for list of the evaluation dataset
6. download the pretrained model from link the previous table
7. set the config.output to path to pretrained model weights
8. run eval/eval.py
9. the output is test.log contains the evaluation results over all epochs

evaluation on IJB-B and IJB-C:

1. Please apply for permissions from NIST before your usage NIST_Request
2. run eval/IJB/runIJBEval.sh

Differentiable architecture search training

The code of NAS is available under NAS

To-do

• Add pretrained model
• Training configuration
• Add NAS code
• Add evaluation results
