WebOct 16, 2024 · Hierarchical triplet loss (computed on a mini-batch of M ) can be formulated as, LM=12ZM ∑T z∈T M[∥∥xza−xzp∥∥−∥xza−xzn∥+αz]+. where T M is all the triplets in the mini-batch M, and ZM=A2lmA2tC1t is the number of triplets. Each triplet is constructed as T z=(xa,xp,xn), and the training triplets are generated as follows. WebExample selection techniques are relatively less studied. For the contrastive loss it is common to select from all posi-ble pairs at random [3,6,11], and sometimes with hard negative mining [27].
