Hello Ryan, Kudos to you for this great project. One small issue.... I tried many many ways of specifying the blacklisted features in the file (csv, tsv, json) before I...
Hi Ryan -- this looks like a great project. I'm a big fan of Go. I would like to restrict the features (a.k.a. the independent variables available for the next...

BestSplitBigCatIter is too slow. Possibly investigate using fully randomized search earlier or "Stochastic Greedy Algorithms: A leaning based approach to combinatorial optimization" [1] as in rf-ace. [1] http://www.thinkmind.org/index.php?view=article&articleid=soft_v4_n12_2011_1
I made a small patch on my own fork to report a little bit more data with `-test` when `growforest` is finishing. It looks like this: ``` Error: 0.06121835978431722 Accuracy:...
I have this sweet matrix, but I have very little idea what it means :) ``` N:sold_price 0 0 0 NaN 0 0 N:current_list_price 3.3253227556326355e+13 3215 2.672728164839731e+15 2.672728164839731e+15 40 1.675...
