SegXAL: Explainable Active Learning for Semantic Segmentation in Driving Scene Scenarios

AI models require massive amounts of labeled data, which is expensive and time-consuming to create. SegXAL addresses this by using active learning to identify which unlabeled images are most important to label, potentially reducing annotation costs while maintaining model performance in autonomous driving scenarios.

Explainability is essential for real-world AI deployment. The paper demonstrates that showing why an AI model makes decisions—through visual error masks and uncertainty measures—helps human experts understand and trust the system, rather than treating it as a "black box."

Humans and AI should work together, not separately. SegXAL implements a "human-in-the-loop" approach where machine learning systems actively ask human experts for help on uncertain cases, combining human judgment with AI efficiency rather than replacing one with the other.

Uncertainty matters as much as accuracy. The model uses entropy-based uncertainty measures to identify where it's least confident, allowing it to ask for human feedback precisely where it's needed most—a more efficient strategy than random labeling.

Collaborative intelligence can improve safety-critical applications. For autonomous driving scenarios, this approach enables AI systems to acknowledge their limitations and seek human expertise on edge cases, which is crucial for responsible deployment in real-world driving situations.
