datascience Classifying architectural elements using AI (ML and neural networks): problem statement I've recently finished the IBM's Avanced data science specialization and as capstone project I thought about being able identify the architectural elements present in an image: is it a column? A vault? Or a bell tower? Let's see what can we achieve! The problemSeveral moments in my live I faced
