This video uses a pasta machine to show how neural networks work. Each time a photo goes through the machine, it becomes simpler and more pixelated — but you can still recognize what’s in it. This is similar to how Convolutional Neural Networks (CNNs) process images step by step.

Early layers in a CNN focus on simple patterns like edges or colors, rather than tiny details. By breaking the image down gradually, the network avoids getting overwhelmed by noise and learns to recognize the most important features first. Just like in the video, each layer simplifies the image a bit more, helping the system focus on the bigger picture.

In the end, even with fewer details, the main object — like a dog — stays recognizable. This is how CNNs can understand complex images and make accurate predictions. As the network continues to learn, it can also distinguish between different objects, like recognizing whether an image contains a dog or a cat. By focusing on the most important features, the CNN can identify the specific characteristics that differentiate a cat from a dog, even if the images become more abstract and pixelated.
