In neural networks, what does the term "deep learning" typically refer to?

• A network with more than 2 total layers (including input and output)
  

• A network with 2 or more hidden layers (excluding input and output)
  

• A network with only 1 hidden layer
  

• Any neural network trained using gradient descent

In the context of classification and geometry, what is true about a hyperplane?

• A hyperplane always has three dimensions regardless of the space it is in

• A hyperplane is the same as the input space

• A hyperplane has one dimension less than the space it is in and helps divide that space

• A hyperplane can only exist in 3D space
