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. WebAll these improved losses share the same idea: maximizing inter-class variance and minimizing intra-class variance. In this paper, we propose a novel loss function, namely large margin cosine loss (LMCL), to realize this idea from a different perspective.

It takes a different approach in adding a margin to softmax loss. Instead of multiplying m to θ like in L-Softmax and A-Softmax, it introduces the margin in an additive manner by changing the ψ(θ) to 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 jean burns gonzales tx

These methods incorporate a ﬁxed ad-ditive margin to all the classes, ignoring the class imbal-ance problem.

WebIn SphereFace [9], the margin m is multiplied to θ, so the angular margin is incorporated into the loss in a multiplicative way.In our proposed loss function, the margin is enforced by subtracting m from cos θ, so our margin is incorporated into the loss in an additive way, which is one of the most significant differences than [9].It is also worth mentioning that …
