Mainly the role of the working gas and its pressure, toroidal electric field orientation and breakdown electric field will be investigated. The physical background is rather known but application of learning machines can help to extract more interesting information. \par {\bf Reports:} \href{/Education/ExperimentMenu/BreakdownStudies/13MO/Report_MO}{ Learning machines report } {\bf Example of use:} \begin{verbatim} ./predict_breakdown.py --train --plot ./predict_breakdown.py --test --Ub=400 --Ucd=500 --pressure=27.84 --Tcd=0.01 ./predict_breakdown.py --outliers \end{verbatim} {\bf Links to files :} \begin{itemize} \item \href{predict_breakdown.py}{predict\_breakdown.py} - the algorithm itself \item \href{data_object.py}{data\_object.py} - class Data \item \href{data_breakdown.npz}{data\_breakdown.npz} - data from shot 5000 to 10700 - see \href{/SW/data_mining}{data\_mining} for more details \end{itemize} \includegraphics[scale = 0.5]{graf.gif}
