Webb1 jan. 2024 · LwF.MC refers to a multi-class classification using the LwF [9] algorithm which is discussed in the next section. The mentioned algorithm uses the distillation loss during learning, as iCaRL does, but without the need for an exemplar-set. Webb对于该保存哪些数据的问题，iCaRL 的样本管理可以分为两部分：取样器和剔除器取样器将计算同一个类别中（指在存储容器中的数据），当前样本特征向量与样本平均特征向量的距离（其实讲不太准确），对距离从小到大排序，将距离最小的前m个确定为需要存储的

Webb(LwF, iCARL) where the network is learned from scratch. In this paper, we propose a method which performs rehearsal with features. Unlike existing feature-based methods, we do not generate feature descriptors from class statistics. We preserve and adapt feature descriptors to new feature spaces as the network is trained incrementally. Webb14 apr. 2024 · 获取验证码. 密码. 登录 teradrive reviews
