"DeepFace: Closing the Gap to Human-Level Performance in Face Verification"
最早的深度學習人臉辨識, 已有 metric learning 的觀念 (使用 siamese network)
但, 無權值共享的 CNN 帶來過多的參數, 3D alignment 也顯得過度複雜
- "Deep Face Recognition"
*http://cis.csuohio.edu/~sschung/CIS660/DeepFaceRecognition_parkhi15.pdf
著名的 VGG Face, 整套流程包含 face dataset 的建立
- "FaceNet: A Unified Embedding for Face Recognition and Clustering"
用 triplet loss 產生 128 維的 FaceNet embeddings (此向量空間內的距離代表人臉的相似程度), LFW 準確度超過 99%
網路結構:
- (A) "Very deep convolutional networks for large-scale image recognition. In International Conference on Learning Representations"
*https://arxiv.org/pdf/1409.1556/
經典的 VGG Network, 包含 VGG16, VGG19
- "Going Deeper With Convolutions"
http://openaccess.thecvf.com/content_cvpr_2015/papers/Szegedy_Going_Deeper_With_2015_CVPR_paper.pdf
GoogLeNet, 使用 3x3, 1x1 convolution 構成 inception 網路模組
- "Deep residual learning for image recognition"
http://openaccess.thecvf.com/content_cvpr_2016/papers/He_Deep_Residual_Learning_CVPR_2016_paper.pdf
residual network, 解決梯度消失問題, 讓訓練 100 (甚至1000) 層以上的深度學習變得容易
- "MobileNets: Efficient Convolutional Neural Networks for Mobile Vision Applications"
https://arxiv.org/abs/1704.04861
mobile net, 小而快的網路， 但犧牲準確度，
A. "Labeled Faces in the Wild: A Database for Studying Face Recognition in Unconstrained Environments"
