Summary of Positioning Error in the East Direction on Test Data Sets
Our algorithm outperforms all of the baselines on the test data sets. Note that the median, minimum, and maximum errors in the east direction were unavailable for the attention-based neural network baseline.
| Error Metric (m) | Kalman Filter | Attention (Kanhere et al., 2022) | Loose GNN + Kalman Filter (Mohanty & Gao, 2022) | Our Approach |
|---|---|---|---|---|
| Mean | 4.6 | 5.9 | 3.5 | 1.1 |
| Median | 4.5 | - | 3.4 | 1.1 |
| Minimum | 1.2 | - | 2.1 | 0.6 |
| Maximum | 14.1 | - | 4.8 | 1.8 |
