You can specify how losses get reduced to a single value by using a reducer : from pytorch_metric_learning import reducers reducer = reducers.SomeReducer() loss_func = losses.SomeLoss(reducer=reducer) loss = loss_func(embeddings, …
人脸识别的loss设计经过了若干年的发展，从最开始的softmax loss， 到centerloss ，到 triplet loss 再到现在的 arcface loss 和 circle ， ... pytorch的原文介绍如上图所示，我们使用的pytorch的混合精度实现，也有nvidia的apex实现，有兴趣的可以瞧瞧，个人觉得pytorch ...
In this paper, we propose an Additive Angular Margin Loss (ArcFace) to obtain highly discriminative features for face recognition. The proposed ArcFace has a clear geometric interpretation due to the exact correspondence to the geodesic distance on the hypersphere. We present arguably the most extensive experimental evaluation of all the recent ...
