Scoring and classification of the S/N and CNN. Top and middle: frequency distributions of aggregated scores assigned to the negative group (red) against the positive group (blue) for both methods. The scores represent the predicted likelihood of a given spectrum to belong to the positive group. The probabilistic scores assigned by the CNN provide a better separation of the groups (i.e. “conspicuity”) than S/N scores. Classification predictions are set by a threshold for a FDR at 5%. Lower: maximal amount of planets recovered in the mock data by the S/N, perceptron (PCT) and both CNNs, within a maximal FDR of 5%.
