Hi, this is currently used in Theano! In fact, it is a John S. that implemented it in NumPy to allow fast gradient of the advanced indexing in Theano. It allow code like: matrix1[vector1, vector2] += matrix2 where there is duplicate indices in the vector In looking at the code, I saw it use at

[Numpy-discussion] ANN: pandas 0.11.0 released!

2013-04-23 Thread Wes McKinney
hi all, We've released pandas 0.11.0, a big release that span 3 months of continuous development, led primarily by the intrepid Jeff Reback and y-p. The release brings many new features, performance and API improvements, bug fixes, and other goodies. Some highlights: - New precision indexing fie

Re: [Numpy-discussion] ANN: NumPy 1.7.1 release

2013-04-23 Thread Frédéric Bastien
Hi, A big thanks for that release. I also think it would be useful to do a release candidate about this. This release changed the behavior releated to python long and broke a test in Theano. Nothing important, but we could have fixed this before the release. The numpy change is that a python lon

[Numpy-discussion] Vectorized percentile function in Numpy (PR #2970)

2013-04-23 Thread Jonathan Helmus
Back in December it was pointed out on the scipy-user list[1] that numpy has a percentile function which has similar functionality to scipy's stats.scoreatpercentile. I've been trying to harmonize these two functions into a single version which has the features of both. Scipy PR 374[2
