Brushfire

Brushfire is an open-source Scala framework for distributed supervised learning of decision tree ensemble models, designed for flexibility and scalability in large data environments. It supports binary/multi-class classification, works with numeric and categorical features, and uses Hadoop/Scalding for distributed processing. Brushfire is intended for data scientists, machine learning engineers, and developers looking for customizable, extensible tree-based learning techniques in Scala, with advanced features such as k-fold cross validation, random forests, and feature importance calculations.
