RestoreAI - Pattern-based Risk Estimation Of Remaining Explosives

2025-07-26

AI Summary

To address the low efficiency and coarse risk assessment in post-conflict landmine clearance, this paper proposes RestoreAI—a novel AI-driven risk prediction framework that introduces spatial distribution pattern modeling of landmines for the first time. Methodologically, it integrates three complementary pattern solvers: linear (PCA), nonlinear (principal curves), and Bayesian prior-based modeling—jointly characterizing mine clustering, linear emplacement patterns, and epistemic uncertainty in risk estimation. Experiments on real-world demining data demonstrate that the optimal solver improves single-step clearance efficacy by 14.37 percentage points and reduces total mission time by 24.45%, significantly accelerating safe land release. This work establishes a new paradigm for intelligent explosive ordnance risk assessment grounded in interpretable spatial pattern analysis.

Abstract

Landmine removal is a slow, resource-intensive process affecting over 60 countries. While AI has been proposed to enhance explosive ordnance (EO) detection, existing methods primarily focus on object recognition, with limited attention to prediction of landmine risk based on spatial pattern information. This work aims to answer the following research question: How can AI be used to predict landmine risk from landmine patterns to improve clearance time efficiency? To that effect, we introduce RestoreAI, an AI system for pattern-based risk estimation of remaining explosives. RestoreAI is the first AI system that leverages landmine patterns for risk prediction, improving the accuracy of estimating the residual risk of missing EO prior to land release. We particularly focus on the implementation of three instances of RestoreAI, respectively, linear, curved and Bayesian pattern deminers. First, the linear pattern deminer uses linear landmine patterns from a principal component analysis (PCA) for the landmine risk prediction. Second, the curved pattern deminer uses curved landmine patterns from principal curves. Finally, the Bayesian pattern deminer incorporates prior expert knowledge by using a Bayesian pattern risk prediction. Evaluated on real-world landmine data, RestoreAI significantly boosts clearance efficiency. The top-performing pattern-based deminers achieved a 14.37 percentage point increase in the average share of cleared landmines per timestep and required 24.45% less time than the best baseline deminer to locate all landmines. Interestingly, linear and curved pattern deminers showed no significant performance difference, suggesting that more efficient linear patterns are a viable option for risk prediction.
