[Scikit-learn-general] onehotencoder and data load

2014-12-15 Thread Pagliari, Roberto
When using OneHotEncoder, is it possible to have one integer per feature as the output, as opposed to binary representation? Also, when using OneHotEncoder, what would be the method to load data (.csv) with mixed type (number and categorical)? Thanks, --

Thanks all, I am just thinking to build an anomaly (novelty) detector using one class SVM with manual inspection to detected anomaly as a feedback to update the normal model. i will think of something else :) Regards, AdyWP ---

Hey all. Afaik we don't currently have continuous integration for OS X. A colleague just told me that travis does that in closed beta and you just have to ask. Olivier, do you want to look into that? Otherwise I can. Cheers, Andy --

Yes, unfortunately that's the nature of SVM. I However, there have been implementations with on-line learning capabilities for SVM that are (promised to be) nearly as accurate as the batch learning variant. Maybe the partial_fit could be a useful task for the GitHub "issue" list. Here would be
