WebDec 1, 2024 · In this research, to jointly enforce inter-class separation and intra-class compactness, we add an additive angle mini-margin to the target angle associated with the cosine margin to formulate a novel loss function called additive cosine margin loss (ACML) for deep fashion style recognition. WebMar 28, 2024 · Based on this, the sample groups are considered as hard sample groups should satisfy the following rule: the cosine distance between the anchor and the positive sample is smaller than that between the anchor and the negative sample as shown in Fig. 2. The formulation is as follows: consine(f (xai),f (xpj)) Webadditive cosine margin. ArcFace [14], proposed by InsightFace, introduces another additive margin, which directly adds the margin to the angle instead of to the cosine, so that the farringdon indian
