M$^3$Exam: Benchmarking Multimodal Memory for Realistic User-Agent Interactions

2023-10-10 · Source: cs.CL updates on arXiv.org · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Robotics & Autonomous Systems · Depth: Expert, extended

Summary

M3Exam is a novel query-centric multimodal conversational memory benchmark designed to evaluate language agents in realistic user-agent interactions. It addresses limitations of existing benchmarks by focusing on reasoning over authentic multimodal files and interpreting implicit user information across multiple sessions. The benchmark features 239 multi-session conversations, 15 persona scenarios, 3,025 rounds, 1,799 multimodal artifacts, and 5,150 evaluation questions. Initial benchmarking of Multimodal Large Language Models (MLLMs) and memory systems on M3Exam reveals significant challenges in cross-modal grounding, cross-session reasoning, and the efficiency of accumulating multimodal context, with the strongest frontier MLLM achieving only 0.549 overall. To address these issues, the paper introduces M3Proctor, a modality-aware memory method that improves accuracy by 13% and reduces index-construction time and retrieved tokens by over 70% by consuming raw visual sources only on demand.

Key takeaway

For Machine Learning Engineers developing multimodal conversational agents, current systems face significant challenges in handling cross-modal reasoning and implicit information inference over long-term histories. You should explore modality-aware memory methods like M3Proctor, which improves accuracy by 13% and drastically cuts token consumption and index-construction time. Implementing such cascaded retrieval strategies can enhance agent performance on complex, realistic interactions while optimizing operational costs.

Key insights

Realistic user-agent interactions demand multimodal memory benchmarks that evaluate cross-modal grounding and implicit inference.

Principles

• Multimodal memory requires storing, retrieving, and reasoning over fragmented text, images, and documents.
• Indiscriminately injecting raw visual sources inflates token budgets and buries decisive evidence.

Method

M3Proctor detects query modality bias, re-ranks evidence, and uses a cost-aware cascade to consume raw visual sources only on demand.

In practice

• Project raw modalities into searchable textual surrogates with modality tags.
• Dynamically detect query bias to determine if raw visual sources are needed.
