Lyrics

[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
