structing knowledge with a safety hierarchy

  • general / safe concepts
  • specific / unsafe concepts

why Hyperbolic space?

  • 유클리드 공간은 깊은 계층관계 표현에 어려움, high distortion
  • 하이퍼볼릭 공간은 원점에 거리에 지수적으로 비례해 규모가 증가함, low distortion

hysac : hyperbolic safety-aware CLIP

  • safe text < safe image < unsafe text < unsafe image

hyperbolic safety-aware contrastive loss을 통해 contrastive learning, contrastive loss와 entailment loss

hyperbolic entailment cones for hierarchical safety
