Proxy anchor loss代码
WebbRanked List Loss使用的采样策略很简单，就是损失函数不为0的样本，具体来说，对于正样本，损失函数不为0意味着它们与anchor之间的距离大于 α − m \alpha-m α − m, 类似的，对于负样本，损失函数不为0意味着它们与anchor之间的距离小于 α \alpha α ，相当于使得同一类别位于一个半径为 α − m \alpha-m α − ... WebbAbstract. The recent proxy-anchor method achieved outstanding performance in deep metric learning, which can be acknowledged to its data efficient loss based on hard example mining, as well as far lower sampling complexity than pair-based approaches. In this paper we extend the proxy-anchor method by posing it within the continual learning ...

The former class can leverage fine-grained semantic relations between data points, but slows convergence in general due to its high training complexity. does heat rash spreadWebbGiven a selected data point as an anchor, proxy-based losses consider its relations with proxies.
