"Gradient Boosted Trees? Deep Learning? In less than 5 minutes? You Bet!"
New Machine Learning Algorithms
We’ve added 4 new algorithms for machine learning, and I am still having a hard time figuring out which one I like the most:
- Gradient Boosted Trees
- Deep Learning
- Generalized Linear Models
- A brand-new implementation of Logistic Regression
Naturally, I gave them a test run on some data sets, and was pretty freakin’ impressed with the prediction accuracy, automatic tuning capabilities, and runtimes. On the well-known Sonar data set, for example, I consistently achieved performance results of 78% to 80% without any parameter tuning. This is a nice bump over other algorithms which only get up to 70% to 75% after heavy optimization circles.
This lift in performance can in part be attributed to the fact that these algorithms tune themselves. They are designed to find the best parameter settings for optimizing prediction accuracy. This not only delivers better accuracy; but also reduces some of the effort required for tuning these bad boys.
