I didn't see sparse vector support. Assuming I didn't just overlook it, is it on the roadmap?

- aklein 13y agoDepends what you mean by sparse vector support. Maybe what you're interested in is best served by Series: val s = Series(Vec(1,2,3), Index(0,5,10)) This gives you s: org.saddle.Series[Int, Int] = [3 x 1] 0 -> 1 5 -> 2 10 -> 3 Then, for instance, s(5,10) res0: org.saddle.Series[Int,Int] = [2 x 1] 5 -> 2 10 -> 3
- MLnick 13y agoFor me at least, sparse vector support means you can do elementwise operations (on the non-sparse elements) and in particular linear algebra like vector dot-products and matrix-vector multiply.
- saintx 13y agoBy sparse vector support, do you mean the Sparse Fast Fourier Transform reported by MIT last year? http://www2.technologyreview.com/article/427676/a-faster-fourier-transform/ http://www2.technologyreview.com/article/427676/a-faster-fou...
