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. -- Olivier http://twitter.com/ogrisel - http://github.com/ogrisel ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
