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 and modern generative methods, WisePanda increases Top-50 matching
accuracy from 34% and 38% to 52% with statistical significance among more than one
thousand candidate fragments, accelerating archaeologists's efficiency in rejoining fragmented bamboo
slips.
