17:10 < robertohueso> Hi everyone! :) I'm currently working on implementing the "Subspace Tree" from this paper http://papers.nips.cc/paper/3539-fast-high-dimensional-kernel-summations-using-the-monte-carlo-multipole-method.pdf

17:12 < robertohueso> So far I've been working on the implementation of this as a statistic that could work (at least) for KD-trees, but there's something in the paper that it's not very clear to me and if that's the case, it would probably require to implement a whole new tree data structure instead of just a statistic

17:14 < robertohueso> the problem is how many dimensions am I suposed to preserve on each level of the tree? From Figure 1 I can see they reduce 1 dimension per level in the tree. i.e. if a dataset has 20 dimensions, the tree's depth would be 20, is that right?

17:32 < rcurtin> hey robertohueso, sorry that I have been a bit out of touch. this week I am at the Kart World Championship

17:32 < rcurtin> but I should have some downtime this afternoon to answer :)

18:27 < robertohueso> That must be fun! are you competing?

18:27 < robertohueso> :)

18:43 < rcurtin> yeah, I am competing. In the first two races I got a 2nd place and a 3rd place (in a bad kart; they draw karts randomly for each race) so I am very happy with how it is going so far

18:46 < zoq> rcurtin: Did you beat the German Team?

19:12 < rcurtin> of course not :(

19:13 < rcurtin> they are incredible! there is also a Dutch guy who is crazy fast and a Belgian

19:13 < rcurtin> they were telling me that they have several kart tracks only a few kms from their house... I am jealous :)

19:51 < zoq> rcurtin: Not sure about the US, but I think Motorsport in Germany has a huge fanbase.

20:05 < rcurtin> yeah absolutely. there are fans in the US but it's generally NASCAR which is a very different style of racing

20:05 < rcurtin> Europeans love their motorsports :)

20:06 < zoq> soccer as well :)

21:31 < gmanlan> rcurtin: you there?

22:36 < rcurtin> gmanlan: maybe a little later tonight, still out for now
