Unless you dataset is really big (e.g. ~1e6 samples), you will need to
pass through your chunked dataset many times when using partial_fit
before reaching convergence.

The fit method is implemented by using the same underlying method is
for partial_fit so you should get the same results of accuracy if you
reuse the same hypeparamaters in the constructor such as alpha.
