[Scikit-learn-general] LDBSCAN

2013-01-28 Thread Oğuz Yarımtepe
Hi, I am interested in LDBSCAN algorithm. It is an outlier detection algorithm that uses local outlier factor + DBSCAN. Can i use it via scikit or any way to implement it using scikit? Cheers -- Oğuz Yarımtepe http://about.me/oguzy --

[Scikit-learn-general] adaptive learning rate?

2013-01-28 Thread Ronnie Ghose
Is there an adaptive learning rate per feature in sklearn? Ex. - --adaptive: use per-feature adaptive learning rates; this is sensible for highly diverse and variable features from https://github.com/JohnLangford/vowpal_wabbit/wiki/Malicious-URL-example

Hi Ariel: There is one matlab implementation for spherical kmeans: http://www.mathworks.com/matlabcentral/fileexchange/28902-spherical-k-means for spherical kmeans and you can have a look at it :) That seems quite simple and may be easily transformed into a python function. Best, Wei On Fri, Jan

I would be much interested. There are a few initiatives out there to interface VW with python, e.g. https://github.com/shilad/PyVowpal I haven't tested this one myself but I have the feeling that it's a proof of concept rather than a long term solution. One important point to keep in mind is th
