Bamboo slips were a key medium for recording philosophy, law, and daily life in ancient East Asia. Their
durability has preserved valuable content for millennia, offering deep insights into early civilizations.
However, many slips have been fragmented into thousands of pieces, posing a major challenge to
reconstruction. We present WisePanda, the first physics-driven deep learning framework for rejoining
fragmented bamboo slips. Designed to support archaeologists, WisePanda features an interpretable pipeline
trained on fracture-based synthetic data and provides Top-k predictions to assist expert analysis.
Restoration of fragmented bamboo slips.
Compared to the leading curve matching method, WisePanda increases Top-50 matching accuracy from 36% to
52% among more than one thousand candidate fragments.
Archaeologists using WisePanda have experienced substantial efficiency improvements (approximately 20 times faster) when
rejoining fragmented
bamboo slips, demonstrating the powerful impact of this collaborative research tool.
