Triplet ñàkk ak jàng metric
Triplet loss dafay jàngal reso neuronal bi ñu def mbir yu nuru yu jege seen biir ak mbir yu wuute yu sori seen biir ci benn espace embedding.
Résumé
It is the foundation behind face recognition, image search, and recommendation systems that need to compare things rather than just classify them.
