7.3. Performance Evaluation Metrics

The performance of AI models in precision agriculture is commonly assessed using the following metrics:

• Mean Absolute Error (MAE):

$$MAE={\displaystyle \frac{1}{n}}\sum \mid y_i-{\widehat{y}}_i\mid$$

(4)

where $y_i$is the actual value, ${\widehat{y}}_i$is the predicted value, and $n$is the number of samples. MAE measures the average magnitude of errors in predictions without considering direction.

• Root Mean Squared Error (RMSE):

$$RMSE=\sqrt{{\displaystyle \frac{1}{n}}\sum (y_i-{\widehat{y}}_i{)}^2}$$

(5)

RMSE penalizes larger errors more than MAE, useful for emphasizing significant prediction deviations [78].

• Coefficient of Determination ($R^2$):

$$R^2=1-{\displaystyle \frac{\sum (y_i-{\widehat{y}}_i{)}^2}{\sum (y_i-\bar{y}{)}^2}}$$

(6)

where $\bar{y}$is the mean of actual values. $R^2$indicates the proportion of variance explained by the model values closer to 1 signify better predictive performance [81].

• Accuracy, Precision, Recall, and F1-Score: (for classification tasks like pest outbreak prediction)

$$\mathrm{Precision}={\displaystyle \frac{TP}{TP+FP}}, \mathrm{Recall}={\displaystyle \frac{TP}{TP+FN}}$$

(7)

$$F1=2\times {\displaystyle \frac{\mathrm{Precision}\times \mathrm{Recall}}{\mathrm{Precision}+\mathrm{Recall}}}$$

(8)

where TP, FP, and FN are true positives, false positives, and false negatives respectively [82].
