[Pharo-dev] Random forest in Pharo

Hi, did anyone implement a Random Forest algorithm in Pharo? https://en.wikipedia.org/wiki/Random_forest -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." --Winston Churchill

[Pharo-dev] Broken examples (GLMExamplesBrowser) issue 16111

I think some examples in GLMExamplesBrowser In Pharo5.0 are broken. see fogbugz issue "16111 Collections being passed as a whole into blocks, instead of each individual object" The confusion about "display-block" and "format-block" is sorted out, so we could close the issue. But it seems the

Re: [Pharo-dev] binary serialization

Good morning, Max. Thank you for the example. I got a little confused, between migrations and substitutions. My issue with no-arg blocks, I believe, is the inability to access my scope object to maintain the object tables. I'm attempting to write my own Materializer, Decoder and

Re: [Pharo-dev] Random forest in Pharo

Not sure you would get enough performance on Pharo per se. Xe may be better off leveraging a multicore enabled external lib. Like caret and doMC on R. Le 14 oct. 2015 17:49, "Serge Stinckwich" a écrit : > I don't think so. > > I followup your message on SciSmalltalk

Robert, As far as I can remember, the problem of substitutions at materialziation time was because... as you may have read, Fuel first serializes "objects" and then the references. At materialization, it first creates the objects and then, on a second step, sets the references betwen objects. So

[Pharo-dev] Corporate sponsored popularity

Just a passing thought... When comparing the popularity of programming languages, maybe technological features are less important than sponsorship by a large tech corporation. Anyhow I don't mind that the masses haven't discovered Pharo. I enjoy it.

So to summarise the great thing about NB is that it does assembly code with pharo syntax, the bad thing about NB is that it does assembly code with pharo syntax. Of course there are not that many people around to be sane enough to write assembly , so of course it will be removed at some point.
