WebBased on this analysis we propose two strategies for training using normalized features. The ˙rst is a modi˙cation of softmax loss, which optimizes cosine similarity instead of inner-product. The second is a reformulation of metric learning by introducing an agent vector for each class.

Table 1 gives the statistics of the Amazon reviews datasets used in our experiment. It can be observed from Table 1 that the ratio of the number of positive reviews to negative reviews, i.e., imbalance ratio (IR), is …
Webfeatures with softmax loss are prone to be separable, rather than to be discriminative for face recognition. Margin-based Softmax. To enhance the feature discrimi-nation for face recognition, several margin-based softmax loss functions (Liu et al.,2024;Wang et al.,2024e;b;Deng et al.,2024) have been proposed in recent years. In summary, WebCosine Based Softmax Loss has a variety of CosFace, ArcFace, etc., but the gradient direction to be updated is the same. The essential difference between these is the length of the gradient, which greatly influences the optimization of the model. Slope length
WebJun 20, 2024 · The cosine-based softmax losses and their variants achieve great success in deep learning based face recognition. However, hyperparameter settings in these losses have significant influences on the optimization path as well as the final recognition performance. Manually tuning those hyperparameters heavily relies on user experience … WebJul 27, 2024 · The softmax loss is typically adept in separating different classes, but not good at making features of the same class compact. To address this, several loss functions are proposed based on the same intuition: maximizing inter-class variance or/and minimizing intra-class variance.
