[Scikit-learn-general] Associating a LabelEncoder with a Classifier?

2013-07-17 Thread Wifi Gi
I'm aware of how to use LabelEncoder to convert string classes to numeric and back again. However, in my applications, I frequently save my models to disk (by pickling them) and reload them when I want to use them. When I use predict(), it of course returns only numerical classes, and if you don't

You can pickle the label encoder too and use inverse_transform to transform the integer predictions back into strings. My 2 yens, Mathieu On Thu, Jul 18, 2013 at 3:56 AM, Wifi Gi prettyflyforawif...@gmail.comwrote: I'm aware of how to use LabelEncoder to convert string classes to numeric and
