Confusion matrix of multinomial outcomes for AFL-GBM analysis of both thresholds to validate reference testing data (10%) after training with actual data for toxin levels and predicted levels using the model (90%).
| AFL (n = 62) | High > 20 ppb | Low ≤ 20 ppb | Total predicted | High > 5 ppb | Low ≤ 5 ppb | Total predicted | |
|---|---|---|---|---|---|---|---|
| High | Low | High | Low | ||||
| Prediction | High | 0 (0.00%) | 0 (0.00%) | 0 (0.00%) | 2 (3.22%) | 2 (3.22%) | 4 (6.45%) |
| Low | 2 (3.22%) | 60 (96.77%) | 62 (100%) | 4 (6.45%) | 54 (87.10%) | 58 (93.55%) | |
