There are a number of different packages for plotting in Julia, and there's probably one to suit your needs and tastes. This section is a quick introduction to one of them, Plots.jl, which is interesting because it talks to many of the other plotting packages.
Do you know of a good library for gradient boosting tree machine learning? preferably: with good algorithms such as AdaBoost, TreeBoost, AnyBoost, LogitBoost, etc with configurable weak classifiers

Get the model using the gbm. For the classification, we use the bernoulli distribution. As the author suggested, normally, we should choose small shrinkage ,such between 0.01 and 0.001; the number of trees, n.trees , is between Summary of the model results, with the importance plot of predictors.
Generalised boosted models, as proposed by and extended by , has been implemented for R as the gbm package by Greg Ridgeway.This is a much more extensive package for boosting than the boost package.
The plots are well written, and sometimes you feel like you're twisting your brain into a knot, trying to figure out the paradoxes. But most importantly it's kind-hearted and beautiful. No doubt 'Doctor Who' will remain a fan-favorite for many years to come.
Using plot_min_depth_distribution, we then get the plot of minimum depth distribution: > GC2_RF_MDD head(GC2_RF_MDD) tree variable minimal_depth 1 1 age 4 2 1 amount 3 3 1 checking 0 4 1 coapp 2 5 1 depends 8 6 1 duration 2 >windows(height=100,width=100) > plot_min_depth_distribution(GC2_RF_MDD,k=nrow(GC2_TestX)) [ 107 ] Random Forests
