[ANN] blog post benchmarking julia vs R Gaussian mixture models

hi all!

I wrote up a quick blog post on my first experiences with the GaussianMixtures.jl package by @davidavdav. My main alternative would be an R implementation, hence the benchmark is comparing 2 R with 2 julia implementations. Julia outperforms R (surprise? :smile:). Comments most welcome!

wow, the R code is a monster compared to the julia bit

yes. well, I couldn’t claim that’s the best possible R code, but I couldn’t figure out how to do the repeat without this spread function. There may be better ways. Also, to be fair, I had another 3 lines of not shown julia code defining the logsumexp function :wink:
