Je travaille sur un projet de classification d’images m\u00e9dicales, plus pr\u00e9cis\u00e9ment des radiographies pulmonaires, pour d\u00e9tecter la pr\u00e9sence de pneumonie. J’ai d\u00e9j\u00e0 une base de donn\u00e9es assez cons\u00e9quente d’images annot\u00e9es, et j’ai exp\u00e9riment\u00e9 avec diff\u00e9rents mod\u00e8les de r\u00e9seaux de neurones convolutifs (CNN) pr\u00e9-entra\u00een\u00e9s, comme ResNet50 et VGG16, en utilisant le transfer learning. Cependant, j’observe que les performances de mes mod\u00e8les plafonnent, et j’aimerais explorer des techniques d’augmentation de donn\u00e9es plus sophistiqu\u00e9es que les transformations de base (rotations, translations, zoom).<\/p>\n

<\/p>\n

Plus pr\u00e9cis\u00e9ment, je me demande : Quelles techniques d’augmentation de donn\u00e9es, au-del\u00e0 des rotations et translations de base, sont les plus efficaces pour am\u00e9liorer la performance des mod\u00e8les de classification d’images m\u00e9dicales (radiographies pulmonaires en particulier) dans le cadre de la d\u00e9tection de pneumonie, et comment puis-je les impl\u00e9menter efficacement en Python, en consid\u00e9rant les sp\u00e9cificit\u00e9s des images m\u00e9dicales (e.g., l’importance de pr\u00e9server la structure anatomique et la n\u00e9cessit\u00e9 d’\u00e9viter d’introduire des artefacts qui pourraient ressembler \u00e0 des pathologies)? Y a-t-il des biblioth\u00e8ques Python sp\u00e9cifiques ou des bonnes pratiques \u00e0 suivre pour ce type d’augmentation de donn\u00e9es appliqu\u00e9es au domaine m\u00e9dical?<\/strong><\/p>\n
