Triplet loss embedding

WebApr 13, 2024 · Motivated by the success of the triplet constraint in audio and video studies , we propose a visual-audio modal triplet framework by adopting audio and visual modal triplet loss to supervise the learning process. For embedding a given instance e, we select embeddings of \(e^+\) and \(e^-\) to form a triplet \(tr=\left\{ e,e^+,e^-\right\} \). WebNov 29, 2016 · Purpose of L2 normalization for triplet network. Triplet-based distance learning for face recognition seems very effective. I'm curious about one particular aspect of the paper. As part of finding an embedding for a face, the authors normalize the hidden units using L2 normalization, which constrains the representation to be on a hypersphere.
