Term

True Positive (TP) An object that has been correctly predicted to be in a specific galaxy class. -
True Negative (TN) An object is correctly predicted not to belong to a class. -
False Positive (FP) An object that is falsely predicted to belong to a galaxy class. -
False Negative (FN) An object that is falsely predicted not to belong to a galaxy class. -

Performance metric

Accuracy The ratio of the correct predictions to the total predictions made by the classifier.
Precision The number of objects correctly predicted to belong to a class divided by the total objects that the classifier predicted to belong to that class.
Recall The objects correctly predicted to belong to a class divided by all the objects that belong to that specific class.
F1-score The harmonic mean of precision and recall.
