[Verse 1] When your model makes predictions every day How do you know if it's performing the right way Four key metrics help you see what's true Precision recall F-one and A-U-C too [Chorus] True positives true negatives count them all False positives false negatives watch them fall In the matrix of confusion find your way Precision recall guide you every day A-U-C shows the curve and F-one finds the balance Measuring AI success with mathematical talents [Verse 2] Precision asks of all you said were right How many truly belonged in that light If you predicted positive one hundred times But only sixty were correct in their signs Then sixty percent precision is your score Quality matters when you're keeping score [Chorus] True positives true negatives count them all False positives false negatives watch them fall In the matrix of confusion find your way Precision recall guide you every day A-U-C shows the curve and F-one finds the balance Measuring AI success with mathematical talents [Verse 3] Recall asks of all that should be found How many did your model track down If ninety cases needed to be caught But you only spotted sixty that you sought Then sixty over ninety is your rate Completeness matters don't be running late [Bridge] F-one score combines them both in harmony Two times precision times recall you see Divided by precision plus recall The harmonic mean that balances it all When precision's high but recall is low F-one will help the true performance show [Verse 4] A-U-C R-O-C draws a special line True positive rate as threshold you define Area under curve from zero up to one Perfect model gets a score of one-point-none Confusion matrix shows the full array Two by two grid lights up the way [Chorus] True positives true negatives count them all False positives false negatives watch them fall In the matrix of confusion find your way Precision recall guide you every day A-U-C shows the curve and F-one finds the balance Measuring AI success with mathematical talents [Outro] Now you know the metrics that matter most Precision recall help you make the boast F-one and A-U-C complete the set Model evaluation goals are met
