Normalization by a pooled sample from group
WebThis paper presents Group Normalization (GN) as a sim-ple alternative to BN. We notice that many classical features like SIFT [39] and HOG [9] are group-wise features and in … Webinvestigation can be achieved even when samples are pooled or if the variation among like samples is small, pooling samples may and can be very cost and time effective. …
