Je participe à une compétition Kaggle pour illustrer mes cours de Big Data et un tutoriel Power BI. Le but est de reconnaître un oiseau à partir d’un enregistrement audio.
Le processus que j’ai choisi valorise l’originalité. Je commence par isoler les « motifs » des chants. Je les enregistre au format image, puis je les regroupe par espèce. Enfin, pour un enregistrement inconnu, j’évalue la probabilité qu’il corresponde à l’une des 182 espèces du dataset.
