CurricularFace: Adaptive Curriculum Learning Loss for Deep Face Recognition - 论文学习 研究背景 卷积神经网络(CNNs)在人脸识别方面的成功主要得益于:海量的训练数据、网络架构、loss function。目前,设计有效的损失函数来增强识别能力是训练深脸神经网络的关键。 目前最先进的人脸识别方法主要采用基于softmax分类损失...
In this pa- per, we propose a novel loss function, namely large mar- gin cosine loss (LMCL), to realize this idea from a different perspective. More specifically, we reformulate the softmax loss as a cosine loss by L2 normalizing both features and weight vectors to remove radial variations...
Above: a wave generated using the cosine function. A cosine wave is the mirror image of a sine wave. Table of common cosine values: Common values of the cosine function x (°)x (rad.)sine(x) 0°01 30°π/60.866025 45°π/40.707107 ...
应该越来越接近loss值的全局最小值。当它逐渐接近这个最小值时,学习率应该变得更小来使得模型不会超调且尽可能接近这一点。余弦退火(Cosineannealing)利用余弦函数来降低学习率,随着迭代...在训练时,梯度下降苏算法可能陷入局部最小值,而不是全局最小值。梯度下降算法可以通过突然提高学习率,来“跳出”局部最小值并...
