Helping Customers in Distress: An LLM-powered Agent that Converses, Probes, and Routes

The paper presents an AI‑powered triaging agent for banks that uses large language models to conduct multi‑turn conversations, ask relevant questions, and classify customer cases for accurate routing to specialist teams. The system is integrated with policy, safety guardrails, and reasoning frameworks, and its performance is evaluated using synthetic digital twins that simulate realistic, labeled dialogues based on historical data. Results show a 30.6% increase in classification accuracy and high satisfaction from subject‑matter experts, demonstrating the effectiveness of targeted probing for scalable banking operations.

Same Stories, Different Journeys: Exploring Persona-Grounded Conversational Agents for Supporting Career Exploration with Peers' Posts

The paper introduces JobMate, a persona‑grounded conversational agent that transforms peer job‑seeking posts into interactive dialogues to aid career exploration. In a study with 24 participants, JobMate helped users select relevant cases, ask follow‑up questions, and articulate constraints, contrasting with a static browsing tool that left reconstruction to users. The authors discuss design implications for blending authentic peer experiences with generative AI.

Marginally Correct Tool Caches Can Reverse Group-Normalized Policy Updates

The paper investigates how marginally correct tool-result caching can affect group-normalized policy updates in reinforcement learning. Using a two-action model, the authors show that sharing a single stochastic result per group can reverse the expected direction of policy updates, leading to a wrong-direction region and a persistent update-variance floor as group size increases. They derive exact finite-group expressions, verify them across numerous configurations, and demonstrate that centering without group standard-deviation scaling preserves the correct update direction.

Resource-Efficient Distributed Recursive Gaussian Processes

The paper introduces two distributed recursive Gaussian process algorithms, ADMM‑RGP and PDMM‑RGP, designed for multi‑output regression in multi‑agent systems. It analyzes their stability and convergence, proposes parameter selection strategies to speed up convergence, and demonstrates that the methods reduce communication overhead while preserving estimation accuracy and consensus. Experiments on a real‑world wind dataset confirm the algorithms’ effectiveness across different communication graph connectivities.

ZO-COSMO: Index-Free One-Hop Mixing for Decentralized Zeroth-Order Optimization

The paper introduces ZO-COSMO, an index‑free one‑hop mixing scheme for decentralized zeroth‑order optimization that couples two‑query estimation with average‑preserving masked consensus. It characterizes the necessary one‑hop condition for sparse communication, derives sharp contraction bounds and convergence guarantees for core and sparse‑momentum updates, and demonstrates empirical gains on synthetic agents and Qwen LoRA workers, achieving notable accuracy improvements over traditional Rand‑k and all‑neighbor mixing methods.

Discover, Falsify, Revise: Auditing Input-Use Claims from Source Code to Predictive Contribution in Agent-Discovered Cell Models

The paper introduces CELLAUDIT, a method for auditing whether inputs claimed to influence predictive models actually do so. By testing if an input can enter the computation, whether predictions depend on it, and if that dependence improves observed responses, the authors evaluate agent-generated predictors on a morphology‑transcriptomics benchmark (BBBC047). Their findings show that many models claim compound contributions that are not supported by the data, and that falsification‑guided revisions can recover genuine input effects while improving performance.
