Abstract
(EN) Introduced here is an approach to training a model to perform facial recognition with a designed dataset-aware loss. This approach is particularly useful for large-scale, multi-dataset training since there are no prerequisites for label cleaning. Dataset-aware loss may be built upon the softmax function with a binary dataset indicator. Such an approach allows the dataset-aware loss to be readily combined with other losses to improve performance.
(FR) Est introduite ici une approche pour entraîner un modèle à effectuer une reconnaissance faciale avec une perte conçue comme compatible avec un jeu de données. Cette approche est particulièrement utile pour l'apprentissage à grande échelle et à multiples jeux de données puisqu'il n'existe aucun prérequis pour le nettoyage d'étiquettes. Une perte compatible avec un jeu de données peut être construite sur la fonction softmax avec un indicateur de jeu de données binaire. Une telle approche permet de combiner facilement la perte compatible avec un jeux de données avec d'autres pertes pour améliorer les performances.
