UnverifiedArcFace is a deep metric learning method optimized specifically for face recognition that outperforms general visual encoders in face identity feature extraction accuracy by introducing an additive angular margin loss function.68% similarUnverifiedUsing detected keypoints to rotate and scale a face into a standard pose (face alignment) before extracting feature vectors can greatly improve feature stability.66% similarUnverified该方法依赖高质量可微的人脸相似度模型作为奖励来源，单步计算成本较高，对画风、构图等奖励信号不明确的属性未必适用61% similar
