WebNov 3, 2024 · Several margin-based losses have been proposed as alternatives of softmax loss in face recognition. However, two issues remain to consider: 1) They overlook the importance of hard sample mining for discriminative learning. 2) Label noise ubiquitously exists in large-scale datasets, which can seriously damage the model’s performance.
Web2003; Agarwal et al., 2005; Usunier et al., 2005), the bounds that we are aware of are not margin-based, and thus do not provide this useful type of discrimination between ranking algorithms in the separable case. Since we are providing a general margin-based bound for ranking in Section 3, we derive al-gorithms which create large margins. banco itau 3716Web2 days ago · OCAM calculates the loss based on the similarity information using these embedding vectors of length S.
