WebFeb 8, 2024 · The number of correct and incorrect predictions are summarized with count values and broken down by each class. A confusion matrix tells us four important things: True Positives (TP): The number of observations where the model predicted the observation is part of the target class (1), and they actually are (1). WebThat is perfectly okay because they are in the same equivalency class. So, it isn't really that they have a different sign, it is just a different representative for that equivalency class (in the rationals, it is similar to $\frac{1}{2}=\frac{2}{4}$; same number, just different representatives for that equivalency class).
