Please download latest shifu here.
After shifu downloading, build your first model with Shifu tutorial. More details about shifu can be found in our wiki pages.
Shifu is an open-source, end-to-end machine learning and data mining framework built on top of Hadoop. Shifu is designed for data scientists, simplifying the life-cycle of building machine learning models. While originally built for fraud modeling, Shifu is generalized for many other modeling domains.
One of Shifu's pros is an end-to-end modeling pipeline in machine learning. With only configurations settings, a whole machine pipeline can be built and model can be much more easy to develop and push to production. The pipeline defined in Shifu is in below:
Shifu provides a simple command-line interface for each step of the model building process, including
- Statistic calculation & variable selection to determine the most predictive variables in your data
- Variable normalization
- Distributed variable selection based on sensitivity analysis
- Distributed neural network model training
- Distributed tree ensemble model training
- Post training analysis & model evaluation
- Distributed Tensorflow on Shifu
Shifu’s fast Hadoop-based, distributed neural network / logistic regression / gradient boosted trees training can reduce model training time from days to hours on TB data sets. Shifu integrates with Pig workflows on Hadoop, and Shifu-trained models can be integrated into production code with a simple Java API. Shifu leverages Pig, Akka, Encog and other open source projects.
Guagua, an in-memory iterative computing framework on Hadoop YARN is developed as sub-project of Shifu to accelerate training progress.
