  • AI and Climate Change
    Deeplearning.ai
    2023
    Au cours de cette formation, j'ai eu l'opportunité de mener deux études pratiques visant à acquérir des compétences avancées dans l'utilisation de modèles d'IA pour des projets liés au changement climatique. 1 - Prédiction de production d'énergie éolienne : Lors du premier projet, j'ai développé une expertise en prédiction de la production d'énergie éolienne à l'aide de modèles d'IA séquentiels. J'ai appris à créer et à formaliser des datasets spécifiques pour ce domaine, puis à entraîner un modèle Keras afin de réaliser des prédictions précises. Le but de cet exercice etant d'optimiser l'utilisation des énergies renouvelables et de réduire l'utilisation d'autres sources d'énergie plus polluantes. 2 - Surveillance de la biodiversité à l'aide de pièges photographiques : Dans le cadre du deuxième projet, j'ai acquis des compétences avancées en ajustement et en augmentation de données pour la surveillance de la biodiversité à l'aide d'images de pièges photographiques. J'ai également appris à fine-tuner un modèle NASNet et à le combiner de manière efficace avec le modèle MegaDetector pour développer une application complète de surveillance de la faune.
