Regression Trees

Estimated time needed: 20 minutes In this lab you will learn how to implement regression trees using ScikitLearn. We will show what parameters are important, how to train a regression tree, and finally how to determine our regression trees accuracy. Objectives After completing this lab you will be able to: Train a Regression Tree Evaluate… Continue reading Regression Trees

This is an IPython notebook, backed by a ruby kernel.

I wrote a kernel in Ruby that adheres to the IPython messaging protocol. Then I modified IPython, with the help of minrk from #ipython, to instantiate my Ruby Kernel instead of its own Python kernel. The IPython KernelManager start the RubyKernel as a subprocess, and from that point communication occurs over ZeroMQ, exactly as if… Continue reading This is an IPython notebook, backed by a ruby kernel.
