New Shapley Value Method Addresses Cyclic Priorities in LLM Valuation

Researchers have introduced the generalized priority-aware Shapley value (GPASV), a new method for valuing complex systems, particularly useful in machine learning contexts. Existing Shapley value methods face limitations with non-binary or cyclic priority data, which GPASV overcomes by using arbitrary directed weighted priority graphs. The paper provides an axiomatic characterization, computational methods, and applies GPASV to evaluate LLM ensembles using the cyclic Chatbot Arena preference graph, demonstrating how different priority balances yield varied valuations.
