Integrated approaches in fusion data analysis

The concept of integrated data analysis in nuclear fusion requires the linkage of data and physical information. Summarizing the key steps for the analysis of transport in the core plasma, benefits of probabilistic modelling of single diagnostics are discussed. Concepts for full diagnostics models consisting of several diagnostics modules and linkage through mapping procedures are given in figures of Bayesian graphical models. Coupling to theory codes is demonstrated by the error estimation of neoclassical error analysis allowing a quantitative physical model validation. As an inverted use of the integrated data analysis approach, goals for the design of diagnostics and sets of diagnostics (meta‐diagnostics) are outlined.
