Principled and Scalable Diversity-Aware Retrieval via Cardinality-Constrained Binary Quadratic Programming

Dimensions overall score 7.0

• A principled and scalable method for diversity-aware retrieval in RAG, offering theoretical guarantees and significant speedups. We propose a principled formulation of diversity retrieval as a cardinality-constrained binary quadratic programming (CCBQP), which explicitly balances relevance and semantic diversity through an interpretable trade-off parameter.problem 35%

• ScienceToStartup currently rates this 7.0/10 on the public viability pass. Extensive experiments demonstrate that our method consistently dominates baselines on the relevance-diversity Pareto frontier, while achieving significant speedup. Code availability is flagged in the production record; the public repository link still needs proof alignment.result 35%
