Histogram of the results on the test set and error on the transit position found by the network. Top panel: histogram of the result of the neural network applied to the test data. Most of the 1-labeled light curves with an exocomet transit yield a probability close to 1, while there are only a few false positives (0-labeled light curves yielding a high probability). Above the chosen threshold, there is more than two order of magnitude between the number of true positives and false positive. Bottom panel: mean error of the position of the transit as a function of the probability of the presence of a transit assigned by the network to the light curves. This error is a few hours at most for the transits identified by the algorithm.
