Quantifying and Expanding the Theoretical Capacity of Late-Interaction Retrieval Models

Innovation Summary

Quantifying and Expanding the Theoretical Capacity of Late-Interaction Retrieval Models: Leveraging our theoretical framework, we introduce Signed MaxSim which allows late-interaction models to exactly replicate any real-valued inner product, something we prove standard MaxSim is not.

Executive Summary

Quantifying and Expanding the Theoretical Capacity of Late-Interaction Retrieval Models: Leveraging our theoretical framework, we introduce Signed MaxSim which allows late-interaction models to exactly replicate any real-valued inner product, something we prove standard MaxSim is not. Why it matters: Overall signal 81/100 driven by novelty 100 and practical impact 84. Primary categories: ColBERT, Conjunctive Normal Form, MaxSim similarity, Signed MaxSim, inner product, k-sparse vectors. Community signal includes 2 upvote(s) and 1 comment(s), which helps separate durable interest from title-only curiosity. Implementation angle: Implementation potential scores 75/100; prioritize adaptation paths for internal agent, evaluation, or platform workflows. No linked repository is present, so expect more translation work before the ideas are production-ready. Technical depth scores 100/100, so a quick skim should focus on architecture, data, and evaluation sections before full adoption work. Caveat: No linked implementation is available yet, which raises integration cost and lowers reproducibility confidence.

Why It Matters

• Overall signal 81/100 driven by novelty 100 and practical impact 84.
• Primary categories: ColBERT, Conjunctive Normal Form, MaxSim similarity, Signed MaxSim, inner product, k-sparse vectors.
