TwoRavens is a Web application for statistical modeling. Given a dataset, it automatically identifies interesting relationships and builds models to predict outcomes. Researchers impart substantive knowledge to define new problems and build better models to help solve their research question.


The project has 3 core applications:

Live Demos

Demo TwoRavens D3M
Demo TwoRavens for Event Data
Demo Metadata Service
