Original Data Samples Enhanced
Data augmentation using 'provider.py' effectively solves insufficient original data, improving generalization ability with random rotation, scale scaling, and position migration.
Case Study: Training Convergence Success
Scenario: PointNet++ training for subway station spatial segmentation achieved rapid convergence.
Challenge: Ensuring high data quality and model robustness.
Solution: 137 rounds of training led to a peak accuracy of 0.765708, with average loss stabilizing at 0.428847. This demonstrates excellent training effect.
Results: The model quickly converged, with both training mean loss and accuracy curves stabilizing, indicating high data quality and robust learning. Complex stations like sample 1 (exchange station with multiple lines) showed high prediction quality.
