Instance reweighting
Constrained Class reWeighting. Instance reweighting assigns lower weights to instances with higher losses. We further extend this intuition to assign importance weights over all possible class labels. Standard training uses a one-hot label vector as the class weights, assigning a weight of 1 to the labeled class and 0 to all other classes. Nettet28. jun. 2014 · Visual domain adaptation, which learns an accurate classifier for a new domain using labeled images from an old domain, has shown promising value in computer vision yet still been a challenging problem. Most prior works have explored two learning strategies independently for domain adaptation: feature matching and instance …
