A powerful, user-friendly program for deducing patterns and extracting useful information from large data sets.
ExploreHD implements the High Dimensional Model Representations (HDMR) technique pioneered by Prof. Herschel Rabitz and collaborators at Princeton University. HDMR explains the input-output behavior of a system using a hierarchical representation involving input variables acting individually and interacting in pairs as well as triples. The mathematical formulation of HDMR enables efficient global sensitivity analysis, readily providing information about how each input variable impacts each system output.
Whether the data comes from a computer model or experimental observation, ExploreHD helps you to understand and simplify the complex relationship between the inputs and outputs of your system. ExploreHD analyzes your data to determine the sensitivity of the system to the first, second and even third order interactions of the inputs, generating a Fully Equivalent Operational Model (FEOM) which captures the behavior of the system.
