Moco

moco es una implementación en PyTorch de momentum contrast diseñada para el aprendizaje de representación visual auto-supervisado. Sirve como un framework basado en investigación para extraer características de imagen de alto nivel de datasets sin etiquetar, maximizando la similitud entre diferentes vistas de la misma imagen.

El sistema utiliza una arquitectura de codificador asimétrico que consiste en un codificador online de aprendizaje rápido y un codificador de momentum de evolución lenta para estabilizar el entrenamiento. Emplea un enfoque basado en diccionario que compara imágenes de consulta contra una cola dinámica de muestras negativas para aprender características visuales distintivas sin etiquetado humano manual.

El framework cubre el flujo de trabajo de aprendizaje contrastivo de extremo a extremo, incluyendo el aprendizaje de representación visual no supervisada y el análisis de imágenes sin etiquetar. Aprovecha operaciones de tensores aceleradas por GPU para cálculos de similitud de vectores de alta dimensión y entrenamiento de modelos.
