A wide enough NN can represent any arbitrary binary function, but it's not obvious that one can learn it.

- labelbias 6y agoYet the best NNs are deep, not wide.
- benibraz 6y agoWhat do you mean by 'the best'? Deeper architectures are popular because they quiet easy to train. They do work well in practice on many tasks (especially vision) but they have their limits. Infinite wide networks are a newly active field and has recently shown some promising results, theoretically [1, 2] and empirically [3].
