Padding is a key concept in convolutional layers that affects how the filters interact with the input data. There are two primary types of padding: 'same' and 'valid'. 'Same' padding adds zero-valued pixels around the input image, ensuring that the output dimensions are the same as the input dimensions. This is particularly useful when you want to preserve the spatial dimensions of the input throughout the network. 'Valid' padding, on the other hand, means no padding is added, resulting in smaller output dimensions. This can be beneficial for reducing the size of the data as it flows through the network. The choice between 'same' and 'valid' padding depends on the specific requirements of your model and the nature of the data you're working with. Understanding the impact of padding on output dimensions is crucial for effectively designing and optimizing convolutional layers.
