MADS: Model Analysis & Decision Support Documentation Research Downloads Contact menu MADS mads@lanl.gov Documentation Research Downloads Contact MADS Model Analysis & Decision Support open-source high-performance computational framework for data- & model-based analyses in Julia and C MADS can perform: Sensitivity Analysis Parameter Estimation Model Inversion and Calibration Uncertainty Quantification Model Selection and Model Averaging Model Reduction and Surrogate Modeling Machine Learning and Blind Source Separation Decision Analysis and Support MADS can be internally or externally coupled with any existing model simulator. MADS includes built-in analytical solutions for groundwater flow and contaminant transport. MADS includes built-in test functions. MADS includes verification and example problems. MADS performs automatic bookkeeping of model results for efficient restarts and reruns. MADS has been successfully applied to perform analyses related to environmental management. MADS is released in two compatible versions: MADS v1.0 written in Julia (actively developed) MADS v1.1.14 written in C/C++ (continued support) Documentation & Examples Julia version C version search close -- Theory & Research Publications Vesselinov, V.V., Mudunuru, M., Karra, S., O'Malley, D., Alexandrov, B.S., Unsupervised Machine Learning Based on Non-Negative Tensor Factorization for Analyzing Reactive-Mixing, Journal of Computational Physics, 2018 (in review).
