Ioannis Sarafis, Christos Diou, Anastasios Delopoulos
Weighted SVM (or fuzzy SVM) is the most widely used SVM variant owning its effectiveness to the use of instance weights. Proper selection of the instance weights can lead to increa…
Learning Local Feature Aggregation Functions with Backpropagation
Angelos Katharopoulos, Despoina Paschalidou, Christos Diou +1
This paper introduces a family of local feature aggregation functions and a novel method to estimate their parameters, such that they generate optimal representations for classific…
