An Approach Driven Ranking System for Risky Gaits

作者：

Highlights：

• We developed a system to prevent falls by ranking risky gaits.

• Interval-valued intuitionistic fuzzy sets are used to model experts knowledge.

• Gaits are evaluated and optimistic, pessimistic and neutral rankings are provided.

• A new measure score helps in ranking risk of falling of the subjects.

• Entropy measure incorporating hesitancy factor is extended to interval valued region.
