MERID: Multimodal Exploration via Recursive Self-Improvement Agents for Major Depression Analysis

MERID is a framework that uses recursive self‑improvement agents to autonomously develop multimodal pipelines for detecting major depressive disorder. It aligns multimodal records with depression targets, jointly modifies representations, fusion, and predictors, and guides revisions through evidence‑guided evolution to validate improvements before inheritance. Experiments on depression benchmarks show MERID outperforms existing multimodal and agent‑based baselines, especially highlighting the importance of acoustic and linguistic cues.

Learning Meta-Skills for Agent Harness Design in Test-Time AI4AI

The paper introduces a method for a Builder model to learn meta-skills—principles that guide when and how to provide support—to improve the execution environments of a Target model during test time. By training on feedback from the Target on a development set, the Builder constructs harnesses for new tasks using a frozen skill bank. Experiments on Harness-Bench and NewtonBench show that using the full meta-skill bank boosts macro-average performance by 8.95 percentage points compared to no-skill construction and by 12.02 points over directly delivering the same skill bank to the Target.
