Yoda Response: Of course, Avi. One instance where I applied Object-Oriented Programming (OOP) concepts in Python was during the development of the VGG-19 model for landmark detection. I encapsulated the model's architecture within a class, which included methods for forward and backward propagation. This approach allowed me to manage the model's parameters and operations efficiently. Additionally, I utilized inheritance to create subclasses for different types of layers, making the code modular and easier to maintain. Encapsulation helped in keeping the internal workings of the model hidden, exposing only the necessary interfaces for training and evaluation.
