What Is CosFace?
CosFace is a sophisticated algorithm designed to enhance face recognition systems by addressing the challenge of distinguishing between similar facial features. It operates by introducing an angular margin during the training of deep neural networks, effectively increasing the separation between different face classes in the cosine space. This technique is particularly effective in ensuring that the system remains robust even when encountering faces that are closely related in appearance, thereby improving the overall recognition performance across varied datasets.
