[Scikit-learn-general] metric learning algorithms

2013-11-04 Thread CJ Carey
There was a thread back in April about including some metric learning algorithms in scikit-learn. ( http://www.mail-archive.com/scikit-learn-general@lists.sourceforge.net/msg06952.html ) The consensus at that time was to come up with some metric learning code in a separate project first, to get a

[Scikit-learn-general] Sequential Inference for DPMM

2013-11-04 Thread Tejas Kulkarni
Hello guys, Recently I did a lot of work on sequential monte carlo and online variational methods for dirichlet process mixture models among other things. I have never contributed to sklearn but was wondering if an online version of DPMM would be something of an interest to the community. Before I

[Scikit-learn-general] SGDRegressor.sparsify() => ValueError: dimension mismatch

2013-11-04 Thread Eustache DIEMERT
Hi List, I'm currently working on some performance documentation [1] and I wanted to micro-benchmark the dense vs sparse coefficients case. I created a self-contained script and wanted to bench it using line_profiler, but it seems that after the call to `sparsify()` my SGDRegressor can't predict

Hi Eustache, that's quite a bug - thanks for reporting - I fixed it and added a sparsify test to test_common.py - pushed directly to master. thanks, Peter 2013/11/4 Eustache DIEMERT > Hi List, > > I'm currently working on some performance documentation [1] and I wanted > to micro-benchmark t

Great, thanks Oliver! I'll have a look around and I'll try to analyse what I've already used in my past projects. I mainly asked to know if that was something important in particular that you'd like people to focus on, given that there is going to be a 1.0 release pretty soon. Looking forward to c
