and when called on you're able to apply these in a, in a, in a meaningful way to an important problem, right? And in fact, um, the way we design CS230 is actually a microcosm of this. Where, um, you know, you learned about neural nets. Um, then about topics like Batch Norm, ConvNets, sequence models, right? I'm just gonna say RNNs. So, actually you've a breadth within the field of deep learning. And then what happens is, well, then, and the reason I want you to work on the project is so that you can pick one of these areas.
