This is a face recognition for tracking network based on Resnet, with support for training and evaluation on Ascend910, GPU and CPU.
ResNet (residual neural network) was proposed by Kaiming He and other four Chinese of Microsoft Research Institute. Through the use of ResNet unit, it successfully trained 152 layers of neural network, and won the championship in ilsvrc2015. The error rate on top 5 was 3.57%, and the parameter quantity was lower than vggnet, so the effect was very outstanding. Traditional convolution network or full connection network will have more or less information loss. At the same time, it will lead to the disappearance or explosion of gradient, which leads to the failure of deep network training. ResNet solves this problem to a certain extent. By passing the input information to the output, the integrity of the information is protected. The whole network only needs to learn the part of the difference between input and output, which simplifies the learning objectives and difficulties.The structure of ResNet can accelerate the training of neural network very quickly, and the accuracy of the model is also greatly improved. At the same time, ResNet is very popular, even can be directly used in the concept net network.

Face Recognition For Tracking uses a Resnet network for performing feature extraction.
We use about 10K face images as training dataset and 2K as evaluating dataset in this example, and you can also use your own datasets or open source datasets (e.g. Labeled Faces in the Wild)
The directory structure is as follows:
.
└─ dataset
├─ train dataset
├─ ID1
├─ ID1_0001.jpg
├─ ID1_0002.jpg
...
├─ ID2
