Rethinking Next-Visit Diagnosis Prediction Beyond Aggregate Metrics: Retrieval--Memory Multi-Agent Adjudication

arXiv:2611.03826v1 Announce Type: new Abstract: Next-visit diagnosis prediction forecasts the diagnoses documented at a patient's next encounter, turning retrospective electronic health records into prospective clinical prediction. However, conventional aggregate evaluation obscures its multifaceted nature: distributionally, models must handle variable-size diagnosis sets and long-tailed labels; temporally, they must distinguish persistent, newly recorded, and recurrent diagnoses; and both vary with observed history depth. We introduce an evaluation framework along these dimensions and apply it to rule-based heuristics, LLM-based prompting, retrieval, memory, and multi-agent approaches. This reveals that repeating the last visit outperforms most LLM-based approaches overall despite predicting no new or recurrent diagnoses, and that retrieval and memory exhibit distinct profiles whose relative strengths vary across temporal transitions and backbones. Motivated by this, we propose LONGINUS, a retrieval-memory multi-agent adjudication framework combining evidence retrieved from patient records with structured memory of the patient trajectory. Using cross-view agreement as a reliability heuristic, it preserves shared predictions and adjudicates disagreements without revealing their source. Across MIMIC-III and MIMIC-IV with four LLM backbones, LONGINUS achieves the best transition-specific performance among LLM-based methods in nearly all settings while remaining competitive with them on aggregate metrics.

v1.19.0 - Trace Your Workflows, Layer by Layer

Dify 1.19.0 enhances observability with nested workflow tracing, allowing users to follow execution steps inside Workflow Tools, inspect LLM calls, and maintain context across nested invocations. The release also enables portable app packages via App packages, improves Agent file uploads and previews, introduces Skill Hub automation through CLI commands, and upgrades the bundled plugin daemon to version 0.6.14-local. Key changes include support for format v2 app packages, enhanced security, improved editing workflows, and updated environment variables and API endpoints.

A new arXiv paper proposes an intelligent agent framework for traceable multimodal emotion reasoning, supporting evidence verification and prompt repair without weight updates.

On October 26, 2026, arXiv published a preprint paper (ID 2610.31685v1) that proposes a traceable multimodal emotion‑reasoning intelligent agent architecture based on frozen large models. By leveraging modality‑specific perception agents, an integration agent, an MLLM critic, and an evidence‑verification stage, the framework achieves error attribution and adaptive optimization of the prompt space, improving the F‑score for emotion recognition across several open‑source multimodal large models (with 2B–38B parameters) by 0.6–2.2 points on the MER2025 dataset.

Why it matters：This study addresses the trade-off between high instruction fine-tuning costs and the non‑debuggable pipeline of intelligent agents in current multimodal emotion‑reasoning systems by proposing the first end-to-end interpretable framework that integrates evidence citation, certainty verification, failure attribution, and targeted prompt repair. All improvements are implemented without modifying model weights and have been empirically validated across four open-source MLLMs of varying scales, demonstrating both methodological innovation and practical engineering utility.

Deep Insight: How AWS’s Open-Source Multi-Agent System Addresses Five Major Production-Grade Challenges

AWS Solutions Architecture Team has launched Deep Insight, an open-source multi-agent system designed for automated CSV data analysis and natural-language report generation. It systematically addresses five common challenges in production environments—agent orchestration, role-based model selection, stable operation, secure code execution, and observability—and has been validated in real-world scenarios such as LG Electronics and the re:Invent 2025 TechRecon.
