In this work, we used the PyTorch framework for our proposed model training on an NVIDIA RTX 3090 GPU, and we selected area under curve (AUC), recall, and precision as the three main metrics to evaluate the model’s performance. During the network training process, we employed Xavier weight...

triplet loss 【前言】 最近,learning to rank 的思想逐渐被应用到很多领域,比如google用来做人脸识别(faceNet),微软Jingdong Wang 用来做 person-reid 等等。learning to rank中其中重要的一个步骤就是找到一个好的similarity function,而triplet loss是用的非常广泛的一种。 【理解triplet】 如上图所......
