Equation and definition of evaluation parameters.

Term	Equation/Definition
Sensitivity/Recall	$\frac{T P}{T P + F N} \times 100$
Specificity	$\frac{T N}{T N + F P} \times 100$
Accuracy	$\frac{T P + T N}{T P + T N + F P + F N} \times 100$
Precision	$\frac{T P}{T P + F P} \times 100$
F1-score	$2 \times (\frac{R e c a l l \times P r e c i s i o n}{R e c a l l + P r e c i s i o n}) \times 100$
True Positive (TP)	observed pecking = recorded pecking
True Negative (TN)	observed non-pecking = recorded non-pecking
False Positive (FP)	observed non-pecking ≠ recorded pecking
False Negative (FN)	observed pecking ≠ recorded non-pecking
