Hi Simon, just in case you are looking for a Julia-based deep learning framework, there is Mocha.jl (https://github.com/pluskid/Mocha.jl), which is very well designed and documented, and a pleasure to use. cheers, rene Am 16.01.2015 um 19:27 schrieb Simon Danisch sdani...@gmail.com:

[julia-users] What does (1,2,(3,4)...) mean?

Hi, I wanted to append the tuple (3,4) to the tuple (1,2), expecting (1,2,3,4) as output: julia a = (1,2,(3,4)...) (1,2,(3,4)...) It turns out I have to use tuple(1,2,(3,4)...) == (1,2,3,4). I understand (1,2,3,4) and (1,2,(3,4)), but what does the output (1,2,(3,4)...), which has type

Hi, perhaps Quick-Shift clustering might be interesting as well [1]. It is easy to implement, fast, and in contrast to k-means / k-medoids (which it generalizes) has the very appealing property that the initial, hierachical data-structure has to be computed only once - you can then investigate
