Dynamic Mode Decomposition is a way to break down a complicated problem into smaller, easier to understand pieces. It works by looking at how things change over time. It takes a signal, like the sound from a car, and breaks it into smaller bits that tell you more about what is going on. For example, if you have a car that is making a strange noise, you can use Dynamic Mode Decomposition to find out which parts are causing the noise and why. This can be very helpful when it comes to figuring out what is wrong with a car.
