One of the biggest challenges in many fields of studies, such as COVID-19, is to analyze a complex mix of experimental and simulation data, which relies primarily on the intuition of trained experts. Many advanced analysis techniques are often difficult to integrate, leading to a confusing patchwork of analysis snippets too cumbersome for data exploration. To simplify data analysis, LLNL scientists developed a web-based software system that consists a combination of techniques from statistics, machine learning, topology, and visualization. The NDDAV (N-dimensional data analysis and visualization) framework integrates traditional analysis approaches with state-of-the art techniques and custom capabilities which are linked into an interactive environment that enables an intuitive exploration of a wide variety of hypotheses while relating the results to concepts familiar to the users. NDDAV’s modular design provides easy extensibility and customization for different applications, like COVID-19. The NDDAV framework allows for integration of trained expert intuition while analyzing complex mixtures of experimental and simulation data leading to faster, more easily understandable data analysis and visualization.
