Using our system we have tested 6,160 different combinations of SDO/HMI data as input data, and simulated the prediction of GOES X-ray flux for 2 years (2011-2012) with one-hour cadence. We have found that direct comparison of the true skill statistics (TSS) is ill-posed, and used the standard scores ($z$) of the TSS to compare the performance of the various prediction strategies. The best strategies we have found for predicting X, $\\geq$M and $\\geq$C class flares are better than the average of the 6,160 strategies by 2.3$\\sigma$, 2.1$\\sigma$, 3.8$\\sigma$ confidence levels, respectively. The best three's TSS values were $0.745\\pm0.072$, $0.481\\pm0.017$, and $0.557\\pm0.043$, respectively.", "revisions": [ { "version": "v1", "updated": "2015-07-29T04:15:02.000Z" } ], "analyses": { "keywords": [ "fully automated predictor", "x-ray flux", "solar flares", "best threes tss values", "true skill statistics" ], "note": { "typesetting": "TeX", "pages": 43, "language": "en", "license": "arXiv", "status": "editable" } } }
