I tried to search "random forest" on CPAN but got no good luck. https://en.wikipedia.org/wiki/Random_forest
For framework we currently use MXNet, which has API for Python/C++/R, but no Perl. http://mxnet.io/ Thanks. 2017-02-12 2:54 GMT+08:00 James Alton <jamesalton...@gmail.com>: > If you want to learn about machine learning and the first thing you think > is: "What Perl libraries are there for this?", you might be going about it > all wrong. > > *The best machine learning libraries are all written for Python*.
