Historical High-z GRBs. Click a GRB to load features and calculate machine-z and the high-z classification.
Please note machine-z and high-z classification may take few minutes to calculate.
The receiver operating characteristic (ROC) curve for the high-z classifier using the best 8 features.
Performance curves for high-z classifier. The top panel (a) compares the fraction of bursts recommended for follow up and the fraction requested from the classifier. The middle panel (b) shows the purity of the burst sample selected for follow-up (the fraction of bursts that were followed up that are actually at high redshift). The bottom panel (c) shows the efficiently of the classifier (the fraction of all high-redshift bursts that were followed up).
Comparison of corrected machine-z predictions with true redshift. The correlation coefficient between the two quantities is 0.57.
Distribution of relative differences between machine-z predictions and true redshifts.
Please see the following publication for more details on machine-z and the high-z classifier.
