| NDArray (vs Numpy): | |
| + Can use GPU | |
| + Can use with autograd. | |
| + More NN specific functions (convolutions, etc) | |
| + Contiguous memory, better use of the cache, more performant. | |
| - Less functions implemented (although can often make with NDArray) | |
| Gluon NN (vs NDArray) | |
| + Handles parameters for you (uses same functions under the hood) |
